Section I. Course Objectives
Introduction
Diabetes now affects nearly 24 million people in the United States, an increase of more than 3 million in approximately two years, according to new 2007 prevalence data estimates released by the Centers for Disease Control and Prevention (CDC). This means that nearly 8 percent of the U.S. population has diabetes.1
In addition to the 24 million with diabetes, another 57 million people are estimated to have pre-diabetes, a condition that puts people at increased risk for diabetes. Among people with diabetes, those who do not know they have the disease decreased from 30 percent to 25 percent over a two-year period.
The new estimates have both good news and bad news. While it is concerning to know that more people are developing diabetes it is good to see that more people have a greater awareness that they have diabetes. The efforts to increase awareness are working and more people are better prepared to manage this disease and its complications.
Diabetes is a disease associated with high levels of blood glucose resulting from defects in insulin production that causes sugar to build up in the body. It is the seventh leading cause of death in the country and can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations.
Among adults, diabetes increased in both men and women and in all age groups, but still disproportionately affects the elderly. Almost 25 percent of the population 60 years and older had diabetes in 2007.
Meal planning and food selection is an integral part in keeping blood glucose at a healthy level which will prevent or slow down diabetes problems. Health care practitioners should make every effort to creare awareness and encourage screening for diabetes, so more prople can be diagnosed and treated. Early detection and treatment will prevent or delay onset of complications and ensure a better quality of life.

Section II. Diabetes Types, Causes, Risk Factors, and Physiology
Understanding Diabetes
Diabetes is a disease in which the body either doesn't produce insulin, or it doesn't properly use insulin, or both. Insulin is a hormone produced by the pancreas that metabolizes glucose, which is the source of energy for cells in the body.
There are three main types of diabetes:
Type I affects about 10 percent of all diabetes. The body doesn't produce insulin, so extra insulin is needed for it to metabolize any carbohydrates that are eaten.
Insulin cannot be taken orally, so it must taken by injection or by insulin pump, which is a tiny device that connects to the body with plastic tubing and feeds a constant drip of insulin.
With type II diabetes, which is much more common, the body generally produces some insulin, but it isn't able to process it properly. Type II is often associated with obesity, and part of the difficulty for type II diabetics is that the extra insulin, which is circulating unused in the body, also causes the body to hold on to fat cells. A fine balance must be found between managing insulin sensitivity and losing weight.
Most type II diabetics are able to take oral drugs that allow their body to properly use the insulin they produce. Obesity is a known risk factor for type II diabetes, and its incidence has increased as obesity rates have climbed.
The key to good diabetes control is blood sugar, or glucose, management. And the reality is that poor glucose control dramatically increases the risk for health complications related to heart and blood vessel disease: heart attacks, stroke, blindness and peripheral vascular disease, when blood flow to the limbs becomes impaired -- sometimes resulting in amputation.
All of these problems can develop when a trio of factors -- blood glucose, blood pressure and cholesterol levels -- are not kept within recommended ranges. That's why the concept of "control" is such an important aspect of being diabetic.
The goal is to mimic what the body would do if it were producing insulin. Normally the body would make smaller, steady amounts of insulin between meals and overnight. This is called the basal rate. And the body would produce larger amounts when someone eats in order to burn off the carbohydrates. This is called a bolus.
Diabetics who inject insulin generally use two types: a slower-acting product that manages the basal rate, and a quicker-acting bolus insulin when they eat food. The bolus and basal rates work to keep blood sugars constantly in control.
Insulin pumps do much the same thing. These are small devices connected to the body by a small tube. The pump can be used to drip insulin into the body to maintain the basal rate, then give extra boluses with meals.
Diabetes Test
In diagnosing diabetes, physicians primarily depend upon the results of specific glucose tests. However, test results are just part of the information that goes into the diagnosis of diabetes. Doctors also take into account your physical exam, presence or absence of symptoms, and medical history. Some people who are significantly ill will have transient problems with elevated blood sugars which will then return to normal after the illness has resolved. Also, some medications may alter your blood glucose levels (most commonly steroids and certain diuretics (water pills)). The two main tests used to measure the presence of blood sugar problems are the direct measurement of glucose levels in the blood during an overnight fast, and measurement of the body's ability to appropriately handle the excess sugar presented after drinking a high glucose drink.2
Fasting Blood Glucose (Blood Sugar) Level
The "gold standard" for diagnosing diabetes is an elevated blood sugar level after an overnight fast (not eating anything after midnight). A value above 140 mg/dl on at least two occasions typically means a person has diabetes. Normal people have fasting sugar levels that generally run between 70-110 mg/dl.
The Oral Glucose Tolerance Test
An oral glucose tolerance test is one that can be performed in a doctor's office or a lab. The person being tested starts the test in a fasting state (having no food or drink except water for at least 10 hours but not greater than 16 hours). An initial blood sugar is drawn and then the person is given a "glucola" bottle with a high amount of sugar in it (75 grams of glucose), (or 100 grams for pregnant women). The person then has their blood tested again 30 minutes, 1 hour, 2 hours and 3 hours after drinking the high glucose drink.
For the test to give reliable results, the individual must be in good health (not have any other illnesses, not even a cold). Also, they should be normally active (for example, not lying down or confined to a bed like a patient in a hospital) and taking no medicines that could affect their blood glucose. The morning of the test, they should not smoke or drink coffee. During the test, they need to lie or sit quietly.
The oral glucose tolerance test is conducted by measuring blood glucose levels five times over a period of 3 hours. In a person without diabetes, the glucose levels in the blood rise following drinking the glucose drink, but then fall quickly back to normal (because insulin is produced in response to the glucose, and the insulin has a normal effect of lowing blood glucose.) In a diabetic, glucose levels rise higher than normal after drinking the glucose drink and come down to normal levels much slower (insulin is either not produced, or it is produced but the cells of the body do not respond to it).
As with fasting or random blood glucose tests, a markedly abnormal oral glucose tolerance test is diagnostic of diabetes. However, blood glucose measurements during the oral glucose tolerance test can vary somewhat. For this reason, if the test shows that they have mildly elevated blood glucose levels, the doctor may run the test again to make sure the diagnosis is correct.
Glucose tolerance tests may lead to one of the following diagnoses:3Type I Diabetes
Symptoms, Diagnosis, & Treatments of Type 1 Diabetes
Type 1 Diabetes is much less common than Type 2 Diabetes and typically affects younger individuals. Type 1 Diabetes usually begins before age 40 although there are exceptions. In the United States, the peak age at diagnosis is around 14. Type 1 Diabetes is associated with deficiency (or lack) of insulin. It is not known why, but the pancreatic islet cells quit producing insulin in the quantities needed to maintain a normal blood glucose level. Without sufficient insulin, the blood glucose rises to levels which can cause some of the common symptoms of hyperglycemia. These individuals seek medical help when these symptoms arise, but they often will experience weight loss developing over several days associated with the onset of their diabetes. The onset of these first symptoms may be fairly abrupt or more gradual.
Incidence of Type 1 Diabetes
It has been estimated that the yearly incidence of Type 1 diabetes developing is 3.7 to 20 per 100,000. More than 700,000 Americans have this type of diabetes. This is about 10 percent of all Americans diagnosed with diabetes...the other 90 percent have Type 2 Diabetes.
Causes of Type 1 Diabetes
Type 1 Diabetes usually develops due to an autoimmune disorder. This is when the body's immune system behaves inappropriately and starts seeing one of it's own tissues as foreign. In the case of Type 1 Diabetes, the islet cells of the pancreas that produce insulin are seen as the "enemy" by mistake. The body then creates antibodies to fight the "foreign" tissue and destroys the islet cells ability to produce insulin. The lack of sufficient insulin thereby results in diabetes. It is unknown why this autoimmune diabetes develops. Most often it is a genetic tendency. Sometimes it follows a viral infection such as mumps, rubella, cytomegalovirus, measles, influenza, encephalitis, polio or Epstein-Barr virus. Certain people are more genetically prone to this happening although why this occurs is not know. Thus, two people may be infected with the same virus and only one of them who is genetically prone will go on to develop diabetes. Other less common ( very rare) causes of Type 1 Diabetes include injury to the pancreas from toxins, trauma, or after the surgical removal of the majority (or all) of the pancreas.
Hereditary Tendencies in Type 1 Diabetes
Type 1 Diabetes tends to have less tendency to have other family members affected with diabetes than Type 2. In the first large family study of diabetes, less than 4% of parents and 6% of siblings of a person with diabetes also had diabetes. In studies with identical twins less than 50% of the siblings of a person with diabetes also had diabetes versus almost 100% of siblings of people with Type 2 Diabetes. Children of Type 1 diabetic fathers are more likely to develop Type 1 autoimmune diabetes than children of Type 1 diabetic mothers.
Treatment of Type 1 Diabetes
Type 1 Diabetes must be treated with insulin shots. This involves injecting insulin under the skin -- in the fat -- for it to get absorbed into the blood stream where it can then access all the cells of the body which require it. Insulin cannot be taken as a pill because the juices in the stomach would destroy the insulin before it could work. Remember, insulin is a hormone, and like all other hormones, insulin is a protein and therefore it has a very important 3-dimentional structure which is destroyed by the acid in the stomach. Even if it did make it through the stomach, the digestive enzymes secreted by the digestive part of the pancreas would digest the insulin protein molecule. Scientists are looking for new ways to give insulin. But today, shots are the most widely used method. Some new insulin pumps are being developed and tested.Type II Diabetes
Type 2 Diabetes is more common than Type 1 Diabetes. Whereas Type 1 Diabetes was characterized by the onset in young persons (average age at diagnosis = 14), Type 2 Diabetes usually develops in middle age or later. This tendency to develop later in life has given rise to the term "adult onset diabetes". The typical Type 2 Diabetes patient is overweight although there are exceptions. In contrast to Type 1 Diabetes, symptoms often have a more gradual onset. Type 2 Diabetes is associated with insulin resistance rather than the lack of insulin like seen in Type 1 Diabetes. This often is obtained as a hereditary tendency from one's parents. Insulin levels in these patients are usually normal or higher than average but the body's cells are rather sluggish to respond to it. This lack of insulin activity results in higher than normal blood glucose levels.
Incidence of Type 2 Diabetes:
Type 2 Diabetes is the most common type of diabetes. This disease exists in all populations, but prevalence varies greatly, i.e., 1% in Japan, and greater than 40% in the Pima Indians of Arizona. In whites the figure is somewhere between 1-2 percent of the entire population. The high incidence of Type 2 Diabetes in certain groups such as the Pima Indians appears to be a relatively recent development that followed a change in the type of food intake (from relatively little food to plenty of food). With this came the development of obesity within their culture which results in diabetes developing in those that are genetically predisposed. This "urbanization phenomenon" has been most carefully studied in nonwhite populations, but is probably ethnically and racially nonspecific. In other words, obesity tends to promote diabetes in those genetically predisposed regardless of where they live and what their racial background is.
Hereditary aspects of Type 2 diabetes
Type 2 diabetes tends to be fairly hereditary in contrast to Type 1 diabetes. Approximately 38% of siblings and one third of children of people with type 2 diabetes will develop diabetes or abnormal glucose metabolism at some point. The degree of obesity also seems to be a factor with a larger percentage of diabetes developing in those who are more obese. Studies with identical twins showed that 90-100% of the time when diabetes developed in one it would also develop in the other compared with 50% in Type 1 Diabetes.
Causes of Type 2 Diabetes
Development of Type 2 diabetes seems to be multi-factorial...that is, there are a number of issues to blame. Genetic predisposition seems to be the strongest factor. Obesity and high caloric intake seem to be another. Twenty percent of people with this Type 2 Diabetes have antibodies to their islet cells which are detectable in their blood resulting in the expected low levels of insulin, suggesting the possibility of incomplete islet cell. These patients often tend to respond early to oral drugs to lower blood sugar but may need insulin at some point.
Gestational Diabetes
Pregnant women who have never had diabetes before but who have high blood sugar (glucose) levels during pregnancy are said to have gestational diabetes. Gestational diabetes affects about 4% of all pregnant women - about 135,000 cases of gestational diabetes in the United States each year.4
The causes gestational diabetes is not known, but there have some clues. The placenta supports the baby as it grows. Hormones from the placenta help the baby develop. But these hormones also block the action of the mother's insulin in her body. This problem is called insulin resistance. Insulin resistance makes it hard for the mother's body to use insulin. She may need up to three times as much insulin.
Gestational diabetes starts when the body is not able to make and use all the insulin it needs for pregnancy. Without enough insulin, glucose cannot leave the blood and be changed to energy. Glucose builds up in the blood to high levels. This is called hyperglycemia.
Other types of diabetes result from specific genetic conditions, such as maturity-onset diabetes of youth; surgery; medications; infections; pancreatic disease; and other illnesses. Such types of diabetes account for 1 to 5 percent of all diagnosed cases.
Diabetes Risk Factors
The CDC reports that the causes of type 1 diabetes appear to be much different than those for type 2 diabetes, though the exact mechanisms for developing both diseases are unknown. The appearance of type 1 diabetes is suspected to follow exposure to an "environmental trigger," such as an unidentified virus, stimulating an immune attack against the beta cells of the pancreas (that produce insulin) in some genetically predisposed people.
The CDC has identified specific risk factors that may lead to diabetes. The risk factors for each type of diabetes are:5
Based upon CDC surveys it has also been reported that there were a variety of risk factors associated with those people that have diabetes. These include:6
Glucose Metabolism Physiology
Glucose is an essential fuel for the body. The amount of glucose in the bloodstream is regulated by many hormones, the most important being insulin.7
Insulin has been described as the "hormone of plenty" it is released when glucose is abundant and stimulates the following:
Glucagon is the main hormone opposing the action of insulin and is released when food is scarce. Whereas insulin triggers the formation of glycogen (an energy-requiring process, or an anabolic effect), glucagon triggers glycogen breakdown, which releases energy (a catabolic effect). Glucagon also helps the body to switch to using resources other than glucose, such as fat and protein.
Blood glucose levels are not constant they rise and fall depending on the body's needs, regulated by hormones. This results in glucose levels normally ranging from 70 to 110 mg/dl.
The blood glucose level can rise for three reasons: diet, breakdown of glycogen, or through hepatic synthesis of glucose.
Eating produces a rise in blood glucose, the extent of which depends on a number of factors such as the amount and the type of carbohydrate eaten (i.e., the glycemic index), the rate of digestion, and the rate of absorption. Because glucose is a polar molecule, its absorption across the hydrophobic gut wall requires specialized glucose transporters (GLUTS) of which there are five types. In the gut, GLUT2 and GLUT5 are the most common.
The liver is a major producer of glucose. It releases glucose from the breakdown of glycogen and also makes glucose from intermediates of carbohydrate, protein, and fat metabolism. The liver is also a major consumer of glucose and can buffer glucose levels. It receives glucose-rich blood directly from the digestive tract via the portal vein. The liver quickly removes large amounts of glucose from the circulation so that even after a meal, the blood glucose levels rarely rise above 110 mg/dl in a non-diabetic.
The rise in blood glucose following a meal is detected by the pancreatic beta cells, which respond by releasing insulin. Insulin increases the uptake and use of glucose by tissues such as skeletal muscle and fat cells. This rise in glucose also inhibits the release of glucagon, inhibiting the production of glucose from other sources, e.g., glycogen break down.
Use Glucose - Once inside the cell, some of the glucose is used immediately via glycolysis. This is a central pathway of carbohydrate metabolism because it occurs in all cells in the body, and because all sugars can be converted into glucose and enter this pathway. During the well-fed state, the high levels of insulin and low levels of glucagon stimulate glycolysis, which releases energy and produces carbohydrate intermediates that can be used in other metabolic pathways.
Make Glycogen - Any glucose that is not used immediately is taken up by the liver and muscle where it can be converted into glycogen (glycogenesis). Insulin stimulates glycogenesis in the liver by:
Insulin also encourages glycogen formation in muscle, but by a different method. Here it increases the number of glucose transporters (GLUT4) on the cell surface. This leads to a rapid uptake of glucose that is converted into muscle glycogen.
Make Fat - When glycogen stores are fully replenished, excess glucose is converted into fat in a process called lipogenesis. Glucose is converted into fatty acids that are stored as triglycerides (three fatty acid molecules attached to one glycerol molecule) for storage. Insulin promotes lipogenesis by:
In addition to promoting fat synthesis, insulin also inhibits fat breakdown by inhibiting hormone-sensitive lipase (an enzyme that breaks down fat stores). As a result, there are lower levels of fatty acids in the blood stream.
Insulin also has an anabolic effect on protein metabolism. It stimulates the entry of amino acids into cells and stimulates protein production from amino acids.
According to the National Library of Medicine fasting is defined as more than eight hours without food. The resulting fall in blood sugar levels inhibits insulin secretion and stimulates glucagon release. Glucagon opposes many actions of insulin. Most importantly, glucagon raises blood sugar levels by stimulating the mobilization of glycogen stores in the liver, providing a rapid burst of glucose. In 10 - 18 hours, the glycogen stores are depleted, and if fasting continues, glucagon continues to stimulate glucose production by favoring the hepatic uptake of amino acids, the carbon skeletons of which are used to make glucose.
In addition to low blood glucose levels, many other stimuli stimulate glucagon release including eating a protein-rich meal (the presence of amino acids in the stomach stimulates the release of both insulin and glucagon, glucagon prevents hypoglycemia that could result from unopposed insulin) and stress (the body anticipates an increased glucose demand in times of stress).
The metabolic state of starvation in the USA is more commonly found in people trying to lose weight rapidly or in those who are too unwell to eat. After a couple of days without food, the liver will have exhausted its stores of glycogen but continues to make glucose from protein (amino acids) and fat (glycerol).
The metabolism of fatty acids (from adipose tissue) is a major source of energy for organs such as the liver. Fatty acids are broken down to acetyl-CoA, which is channeled into the citric acid cycle and generates ATP. As starvation continues, the levels of acetyl-CoA increase until the oxidative capacity of the citric acid cycle is exceeded. The liver processes these excess fatty acids into ketone bodies (3-hydroxybutyrate) to be used by many tissues as an energy source.
The most important organ that relies on ketone production is the brain because it is unable to metabolize fatty acids. During the first few days of starvation, the brain uses glucose as a fuel. If starvation continues for more than two weeks, the level of circulating ketone bodies is high enough to be used by the brain.
This slows down the need for glucose production from amino acid skeletons, thus slowing down the loss of essential proteins.
Diabetes is often referred to as "starvation in the midst of plenty" because the intracellular levels of glucose are low, although the extracellular levels may be extremely high.
As in starvation, type 1 diabetics use non-glucose sources of energy, such as fatty acids and ketone bodies, in their peripheral tissues. But in contrast to the starvation state, the production of ketone bodies can spiral out of control. Because the ketones are weak acids, they acidify the blood. The result is the metabolic state of diabetic ketoacidosis (DKA). Hyperglycemia and ketoacidosis are the hallmark of type 1 diabetes.
Hypertriglyceridemia is also seen in DKA. The liver combines triglycerol with protein to form very low density lipoprotein (VLDL). It then releases VLDL into the blood. In diabetics, the enzyme that normally degrades lipoproteins (lipoprotein lipase) is inhibited by the low level of insulin and the high level of glucagon. As a result, the levels of VLDL and chylomicrons (made from lipid from the diet) are high in DKA.

Section III. Health Complications of Diabetes
Complications of Diabetes in the United States
Diabetes can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations. Diabetes is the sixth leading cause of death in the United States
The National Institute of Health has identified some of the complications that can arise from diabetes:8
Heart Disease and StrokePreventing Diabetes Complications
Diabetes can affect many parts of the body and can lead to serious complications such as blindness, kidney damage, and lower-limb amputations. Working together, people with diabetes, their support network, and their health care providers can reduce the occurrence of these and other diabetes complications by controlling the levels of blood glucose, blood pressure, and blood lipids and by receiving other preventive care practices in a timely manner.9
Glucose ControlHealth Care Team
The CDC recommends that people with diabetes should see a health care provider who will monitor their diabetes control and help them learn to manage their diabetes. In addition, the health care team people with diabetes may see are endocrinologists, who may specialize in diabetes care; ophthalmologists for eye examinations; podiatrists for routine foot care; and dietitians and diabetes educators who teach the skills needed for daily diabetes management.

Section IV. Diabetes Prevalence, Mortality, and Economic Cost
Diabetes Prevalence
The CDC Diabetes Surveillance System collects, analyzes, and disseminates data on diabetes and its complications. This public health surveillance (disease tracking) of diabetes is viewed by the CDC as critical to:10
According to the CDC's the prevalence of diagnosed and undiagnosed diabetes in the United States in 2007, was for all ages a total of 23.6 million people-7.8 percent of the population.
Prevalence of Diagnosed Diabetes in People Younger than 20 Years of Age
About 186,300 people younger than 20 years have diabetes-type 1 or type 2. This represents 0.2 percent of all people in this age group. Estimates of undiagnosed diabetes are unavailable for this age group.
Sufficient data are not available to derive prevalence estimates of both diagnosed and undiagnosed diabetes for all minority populations. For example, national survey data cannot provide reliable estimates for the Native Hawaiian and other Pacific Islander population. However, national estimates of diagnosed diabetes for certain minority groups are available from national survey data and from the IHS user population database, which includes data for approximately 1.4 million American Indians and Alaska Natives in the United States who receive health care from the IHS. Because most minority populations are younger and tend to develop diabetes at earlier ages than the non-Hispanic white population, it is important to control for population age differences when making race and ethnic comparisons.
Incidence of Diagnosed Diabetes among People Aged 20 Years or Older
A total of 1.6 million new cases of diabetes were diagnosed in people aged 20 years or older in 2007.
Deaths among People with Diabetes
Diabetes was the seventh leading cause of death listed on U.S. death certificates in 2006. This ranking is based on the 72,507 death certificates in 2006 in which diabetes was listed as the underlying cause of death. According to death certificate reports, diabetes contributed to a total of 233,619 deaths in 2005, the latest year for which data on contributing causes of death are available.
Diabetes is likely to be underreported as a cause of death. Studies have found that only about 35 to 40 percent of decedents with diabetes had it listed anywhere on the death certificate and only about 10 to 15 percent had it listed as the underlying cause of death.
Overall, the risk for death among people with diabetes is about twice that of people without diabetes of similar age.
Estimated Diabetes Costs
The American Dietetic Association estimates that the total direct and indirect total annual cost of diabetes in the US is $174 billion in 2007. Medical expenditures totaled $116 billion and were comprised of $27 billion for diabetes care, $58 billion for chronic diabetes-related complications, and $31 billion for excess general medical costs. Indirect costs resulting from increased absenteeism, reduced productivity, disease-related unemployment disability, and loss of productive capacity due to early mortality totaled $58 billion. This is an increase of $42 billion since 2002. This 32% increase means the dollar amount has risen over $8 billion more each year.
The direct medical costs are $116 billion. After adjusting for population age and sex differences, average medical expenditures among people with diagnosed diabetes were 2.3 times higher than what expenditures would be in the absence of diabetes.11
Medical Expenditures Attributed to Diabetes
Medical expenditures are estimated at $116 billion, including $27 billion for care to directly treat diabetes, $58 billion to treat diabetes-related chronic complications, and $31 billion in excess general medical costs.
Indirect Costs of Diabetes
The indirect cost of diabetes was estimated to be $58 billion in 2007. In 2007, diabetes accounted for 15 million work days absent, 120 million work days with reduced performance, 6 million reduced productivity days for those not in the workforce, and an additional 107 million work days lost due to unemployment disability attributed to diabetes.
Causes for Diabetes Increased Cost
The increase in the cost of diabetes reflects three causes:
The actual national burden of diabetes likely exceeds the $174 billion estimate because it omits the social cost of intangibles such as pain and suffering, care provided by non-paid caregivers, excess medical costs associated with undiagnosed diabetes, and diabetes-attributed costs for health care expenditures categories not studied.
According to CDC, in 2007 23.6 million Americans had diabetes, with nearly a third undiagnosed. Another 57 million have pre-diabetes, and are likely to have the disease if they do not alter their living habits. The 23.6 million represents a 13.5% increase from the 20.8 million in 2005. Many factors contribute to this rise, including higher prevalence of overweight and obesity, changes in diagnostic criteria, improved or enhanced detection, decreasing mortality, a growing elderly population, and growth in minority populations in whom the prevalence and incidence of diabetes are increasing.

Section V. Managing Diabetes
Diabetes ABC's
An important concept that has is used by organizations such as the ADA, CDC and the National Institute of Health, is to "Manage the ABCs of Diabetes."
(A) is for A1C. This test shows average blood sugar for the past 2 to 3 months. An A1C test can help monitor how well the treatment plan is working. The ADA recommends that an A1C test be completed twice a year.
(B) is for Blood Pressure. The American College of Physicians has made the following important recommendations.12
(C) is for Cholosterol. Colesterol numbers tell the amount of fat in the blood. HDL cholesterol helps protect the heart. LDL cholesterol can clog arteries and lead to heart disease. Triglycerides are another kind of blood fat the can affect the risk of heart attack or stroke. The ADA recommends that cholesterol be checked at least once a year.
Controlling Risk Factors
This section provides messages that a health care provider should discuss with people with diabetes.
Promote the ABCs - A1C, Blood Pressure, and Cholesterol - It is important to control risk factors for cardiovascular disease. Ask persons with diabetes if they understand the ABCs.
Promote a Healthy Lifestyle - Diabetes can be controlled through a healthy lifestyle. Describe ways this can be accomplished.
Weight Loss Importance
Weight loss helps people with diabetes in two important ways.
Lowering Blood Pressure
Experts say most people with diabetes should try to keep their blood glucose level as close as possible to the level of someone who doesn't have diabetes. The closer to normal the blood glucose is, the lower the chances are of developing damage to the eyes, kidneys, and nerves.
The National Institute of Diabetes and Digestive and Kidney Diseases recommend that the following four things be done every day to lower high blood glucose:13
Blood Glucose Too High or Too Low
Blood glucose that's too high or too low can make the person very sick. Here are some recommendations on how to handle these emergencies from the National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health.14
If the blood glucose level stays over 180, it may be too high. It means the person don't have enough insulin in their body. High blood glucose can happen if they miss taking their diabetes medicine, eat too much, or don't get enough exercise. Sometimes, the medicines they take for other problems cause high blood glucose.
Having an infection or being sick or under stress can also make the blood glucose too high. That's why it's very important to check the blood glucose and keep taking the insulin or diabetes pills when they are sick.
A symptom of high blood glucose levels is if they are very thirsty and tired, have blurry vision, and have to go to the bathroom often. Very high blood glucose may also make them feel sick to their stomach.
Hypoglycemia
Hypoglycemia happens if the blood glucose drops too low. It can come on fast. It's caused by taking too much diabetes medicine, missing a meal, delaying a meal, exercising more than usual, or drinking alcoholic beverages. Sometimes, medicines taken for other health problems can cause blood glucose to drop.
Hypoglycemia can make a person feel weak, confused, irritable, hungry, or tired. They may sweat a lot or get a headache. They may feel shaky. If their blood glucose drops lower, they could pass out or have a seizure.
If a person have any of these symptoms, they should check their blood glucose. If the level is 70 or below, the National Institute of Health advises that the person should have one of the following right away:
After 15 minutes, they should check their blood glucose again to make sure their level is 70 or above. Repeat these steps as needed. Once their blood glucose is stable, if it will be at least an hour before their next meal, have a snack.
If they take insulin or a diabetes pill that can cause hypoglycemia, they should always carry food for emergencies. It's a good idea also to wear a medical identification bracelet or necklace.
If they take insulin, they should keep a glucagon kit at home and also at a few other places where they go often. Glucagon is given as an injection with a syringe and quickly raises blood glucose. They should also show their family, friends, and co-workers on how to give them a glucagon injection if they pass out because of hypoglycemia.
They can prevent hypoglycemia by eating regular meals, taking their diabetes medicine, and checking their blood glucose often. Checking will tell them whether their glucose level is going down. They can then take steps, like drinking fruit juice, to raise their blood glucose.
Hyperglycemia and Ketoacidosis
Hyperglycemia can be a serious problem if it is not treated it. Hyperglycemia is a major cause of many of the complications that happen to people who have diabetes. For this reason, it's important to know what hyperglycemia is, what its symptoms are, and how to treat it.
Hyperglycemia is the technical term for high blood glucose (sugar). High bloodglucose happens when the body has too little, or not enough, insulin or when the body can't use insulin properly.
A number of things can cause hyperglycemia. For example, with type 1 diabetes, they may not have given themselves enough insulin. With type 2 diabetes, the body may have enough insulin, but it is not as effective as it should be.
The problem could be that they ate more than planned or exercised less than planned. The stress of an illness, such as a cold or flu, could also be the cause. Other stresses, such as family conflicts or school or dating problems, could also cause hyperglycemia.
The signs and symptoms include: high blood glucose, high levels of sugar in the urine, frequent urination, and increased thirst.
Part of managing diabetes is checking the blood glucose often. If hyperglycemia is not treated, a condition called ketoacidosis (diabetic coma) could occur. Ketoacidosis develops when your body doesn't have enough insulin. Without insulin, your body can't use glucose for fuel. So, your body breaks down fats to use for energy.
When the body breaks down fats, waste products called ketones are produced. The body cannot tolerate large amounts of ketones and will try to get rid of them through the urine. Unfortunately, the body cannot release all the ketones and they build up in your blood. This can lead to ketoacidosis.
Ketoacidosis is life-threatening and needs immediate treatment. Symptoms include:
Often, blood glucose levels can be lowered by exercising. However, if the blood glucose is above 240 mg/dl, the ADA advises that they check their urine for ketones. If they have ketones, it is advised that they do NOT exercise.
Exercising when ketones are present may make the blood glucose level go even higher. Cutting down on the amount of food they eat might also help. This may require changes to the meal plan. If exercise and dietary changes don't work, their doctor may change the amount of medication or insulin or possibly the timing of when they take it.
Carbohydrates (Carbs) - A1C
Of all the all of the foods, carbohydrates (Carbs) have the most effect on the blood sugar. Counting the carbs or exchanges in the meal should also be used to ensure that the insulin and exercise are on target.
Carbohydrates include starches and sugar foods such as fruit, bread, potatoes, pasta, milk, and sweets. The American Dietetic Association recommends that eating the same amount of carbs each day can help the person reach their A1C goals.
Cholesterol is a fatlike substance that serves several useful functions. The liver makes cholesterol, and we get some from our diet. Cholesterol travels around the body in tiny clumps of fat and protein called lipoproteins. Low-density lipoproteins (LDL) carry cholesterol where it is needed. High-density lipoproteins (HDL) carry leftover cholesterol back to the liver.
When cholesterol levels are high, LDL dumps it in arteries, where it builds up in hard lumps called plaques. For good blood flow, blood vessels need to be flexible and free of plaques. Cholesterol buildup in arteries makes them rigid ("hardening of the arteries") and narrower. The result: high blood pressure, blood clots, even heart attacks and strokes. Luckily, HDL carts away from arteries some of the cholesterol LDL leaves there. For these reasons, it's healthiest to have low LDL cholesterol levels and high HDL cholesterol levels.
Diabetes can upset the balance between HDL and LDL levels:
As a result, in people with diabetes:
Patient Education Program
The design and content of a diabetes patient education program can have a significant impact on their interest in learning. There are many methods used to disseminate information. Historically, the compliance-based approach has been used to improve adherence to the treatment plan established by health care professionals. This model places the health care provider as the director of the client's medical care and assumes the provider knows what is best for the patient. Clients are expected to conform to the practitioner's directions. The ultimate goal is to optimize glucose control to prevent complications. This approach may be more suitable for newly diagnosed or poorly informed patients.
The empowerment model serves to guide patients in making informed decisions about their diabetes management. This approach assumes that patients have the right and the responsibility to be the primary decision-makers in their health care. The health care provider acts as technical resource in the decision making process. There is a sense of partnership between the client and health care provider. This model can work well with the client who is self-directed and motivated.15
These approaches can be alternated or modified to individualize its use. Considerations may include the patient's level of comprehension and experience in making complex, long-term decisions.16
A patient's past experience can affect their readiness to learn. If they have a relative who managed their diabetes poorly with resultant complications, they may transfer that poor experience to their own situation. Also, if they feel no ill effects from hyperglycemia, they may be inclined to not treat their glucose management seriously. Their level of social support can affect their interest in learning. Those with greater support from family and friends are more likely to manage better. Other areas that can affect readiness to learn include: current ability to care for themselves, preferred style of learning (verbal, written, active participation), psychological stability, stress level, cultural influences, ability to read, language barriers, visual acuity, hearing loss, and dexterity.
Adult learners are usually self-directed and are more likely to participate in a process that is relevant. Adults focus on problem-solving rather than learning the information for fact gathering. Learning is maximized when the process is active rather than passive. A non-judgmental approach is recommended to gain the patient's trust so that the health care providers and the patient may work as a team.

Section VI. Setting Targets and Daily Log
Setting Targets
The National Institutes of Health have developed the following targets for the daily management of diabetes.
Glucose: Everyone's blood has some glucose in it. In people who don't have diabetes, the normal range is about 70 to 120. Blood glucose goes up after eating, but returns to the normal range 1 or 2 hours later. According to the National Institutes of Health and the Centers for Disease Control and Prevention, the target glucose range for most people using whole blood is:
Blood Pressure: High blood pressure makes the heart work too hard. This leads to strokes and other problems such as kidney disease. Blood pressure should be checked at every doctors visit or the person may need to check it themselves. According to the National Institutes of Health and the Centers for Disease Control and Prevention, the target blood pressure for most people with diabetes is:
Cholesterol: LDL is the "bad cholesterol" that builds up in the blood vessels. It causes the vessels to narrow and harden, which can lead to a heart attack. The LDL cholesterol should be checked at least once a year. According to the National Institutes of Health and the Centers for Disease Control and Prevention, the target LDL cholesterol for most people with diabetes is:
Following a healthy diet is one of the best things that can do for the heart. The ADA has established that a meal plan to improve the cholesterol levels should, according to the guidelines set by the National Cholesterol Education Program Adult Treatment Panel (ATP III), include:
In addition, other changes in eating habits may help cholesterol levels.
Daily Log Managing Diabetes
The National Diabetes Information Clearinghouse published the following form for each person to use as part of their diabetes plan. It should be completed in conjunction with the health care team to set the blood glucose target levels. This should be completed when the person's blood glucose is checked with a meter. (This form is also developed using the ABC approach to managing diabetes.)17

Section VII. Diabetes Prevention PracticesPrevention
According to the CDC diabetes prevention is proven and possible.18
Preventive Care Practices
Persons with diabetes are at increased risk for serious health complications. Prevention care practices have been shown to be effective in reducing both the incidence and progression of diabetes-related complications.
In 2004, the CDC reported that the following rates of preventive care "Practices with Diabetes" in the United States:19
Diabetes "Cure"
In response to the growing health burden of diabetes, the US Department of Health and Human Services is pursing three activities: prevent diabetes; cure diabetes; and improve the quality of care of people with diabetes to prevent devastating complications.
Both the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC) are involved in prevention activities. The NIH reports that it is involved in research to cure both type 1 and type 2 diabetes, especially type 1. CDC focuses most of its programs on being sure that the proven science is put into daily practice for people with diabetes. The basic idea is that if all the important research and science are not applied meaningfully in the daily lives of people with diabetes, then the research is, in essence, wasted.
Several approaches to "cure" diabetes are being pursued:20
Each of these approaches still creates issues that have to be overcome, such as preventing immune rejection; finding an adequate number of insulin cells; keeping cells alive; and others. But progress is being made in all areas.
Pancreatic Islet Transplantation
The pancreas, an organ about the size of a hand, is located behind the lower part of the stomach. It makes insulin and enzymes that help the body digest and use food. Spread all over the pancreas are clusters of cells called the islets of Langerhans. Islets are made up of two types of cells: alpha cells, which make glucagon, a hormone that raises the level of glucose (sugar) in the blood, and beta cells, which make insulin.
Insulin is a hormone that helps the body use glucose for energy. If the beta cells do not produce enough insulin, diabetes will develop. In type 1 diabetes, the insulin shortage is caused by an autoimmune process in which the body's immune system destroys the beta cells.
In an experimental procedure called islet transplantation, islets are taken from a donor pancreas and transferred into another person. Once implanted, the beta cells in these islets begin to make and release insulin. Researchers hope that islet transplantation will help people with type 1 diabetes live without daily injections of insulin.
The National Institutes of Health has reported that scientists have made many advances in islet transplantation in recent years. Since reporting their findings in the June 2000 issue of the New England Journal of Medicine, researchers at the University of Alberta in Edmonton, Canada, have continued to use a procedure called the Edmonton protocol to transplant pancreatic islets into people with type 1 diabetes. A multicenter clinical trial of the Edmonton protocol for islet transplantation is currently under way, and results will be announced in several years. According to the Immune Tolerance Network (ITN), as of June 2003, about 50 percent of the patients have remained insulin-free up to 1 year after receiving a transplant. A clinical trial of the Edmonton protocol is also being conducted by the ITN, funded by the National Institutes of Health and the Juvenile Diabetes Research Foundation International.21
Researchers use specialized enzymes to remove islets from the pancreas of a deceased donor. Because the islets are fragile, transplantation occurs soon after they are removed.
During the transplant, the surgeon uses ultrasound to guide placement of a small plastic tube (catheter) through the upper abdomen and into the liver. The islets are then injected through the catheter into the liver. The patient will receive a local anesthetic. If a patient cannot tolerate local anesthesia, the surgeon may use general anesthesia and do the transplant through a small incision. Possible risks include bleeding or blood clots.
It takes time for the cells to attach to new blood vessels and begin releasing insulin. The doctor will order many tests to check blood glucose levels after the transplant, and insulin may be needed until control is achieved.
The goal of islet transplantation is to infuse enough islets to control the blood glucose level without insulin injections. For an average-size person (70 kg), a typical transplant requires about 1 million islets, extracted from two donor pancreases. Because good control of blood glucose can slow or prevent the progression of complications associated with diabetes, such as nerve or eye damage, a successful transplant may reduce the risk of these complications. But a transplant recipient will need to take immunosuppressive drugs that stop the immune system from rejecting the transplanted islets.
Researchers are trying to find new approaches that will allow successful transplantation without the use of immunosuppressive drugs, thus eliminating the side effects that may accompany their long-term use. Rejection is the biggest problem with any transplant. The immune system is programmed to destroy bacteria, viruses, and tissue it recognizes as "foreign," including transplanted islets. Immunosuppressive drugs are needed to keep the transplanted islets functioning.
The Edmonton protocol uses a combination of immunosuppressive drugs, also called antirejection drugs, including dacliximab (Zenapax), sirolimus (Rapamune), and tacrolimus (Prograf). Dacliximab is given intravenously right after the transplant and then discontinued. Sirolimus and tacrolimus, the two main drugs that keep the immune system from destroying the transplanted islets, must be taken for life.
These drugs have significant side effects and their long-term effects are still not known. Immediate side effects of immunosuppressive drugs may include mouth sores and gastrointestinal problems, such as stomach upset or diarrhea. Patients may also have increased blood cholesterol levels, decreased white blood cell counts, decreased kidney function, and increased susceptibility to bacterial and viral infections. Taking immunosuppressive drugs increases the risk of tumors and cancer as well.
Researchers do not fully know what long-term effects this procedure may have. Also, although the early results of the Edmonton protocol are very encouraging, more research is needed to answer questions about how long the islets will survive and how often the transplantation procedure will be successful.
A major obstacle to widespread use of islet transplantation will be the shortage of islet cells. The supply available from deceased donors will be enough for only a small percentage of those with type 1 diabetes. However, researchers are pursuing avenues for alternative sources, such as creating islet cells from other types of cells. New technologies could then be employed to grow islet cells in the laboratory.

Section VIII. Medical Nutrition Therapy
Medical Nutrition Therapy (MNT) is one of the most stressed upon as well as most challenging treatment modalities in the management of diabetes. It is an integral part of a successful management plan.
Nutrition management utilizing MNT requires an individualized approach. It involves an assessment of the patient's needs, and a recommendation of a management plan tailoring to each patient's lifestyle and treatment goal. The American Diabetes Association has developed the following position statement of Nutrition recommendations and principles for people with diabetes mellitus.
Clinical Goals of Medical Nutrition TherapyDiabetes Meal Plan
A diabetes meal plan is a guide that says how much and what kinds of food are selected to eat at meals and snack times. A good meal plan should fit in with the persons schedule and eating habits. The right meal plan will help them improve their blood glucose, blood pressure, and cholesterol numbers and also help keep their weight on track. Whether they need to lose weight or stay where they are, the meal plan can help. People with diabetes have to take extra care to make sure that their food is balanced with insulin and oral medications, and exercise to help manage their blood glucose levels.
A healthy diet is a way of eating that that reduces risk for complications such as heart disease and stroke. Healthy eating includes eating a wide variety of foods including vegetables, whole grains, fruits, non-fat dairy products, beans, and lean meats, poultry and fish. There is no one perfect food so including a variety of different foods and watching portion sizes is essential to maintaining a healthy diet. Also, it is recommended that choices are made from each food group to provide the highest quality nutrients. Pick foods rich in vitamins, minerals and fiber over those that are processed.
Meal Planning Recommendations
The ADA and the American College of Physicians (ACP) have developed a guide for making wise food choices. Healthy food choices are vital to controlling blood sugar, blood pressure, and cholesterol. The general guidelines in developing the meal plan are to choose a variety of foods, and to have less fat and salt intake.
The starting point in developing the meal planning is to divide the plate into 4 sections. The ADA and the ACP recommend that foods are grouped into the following sections:22
Additional meal planning considerations include:
Alcohol
Alcohol has calories but no nutrients. Drinking alcohol on an empty stomach can make the blood glucose level too low. Alcohol also can raise the blood fats. For those who drink alcohol, it needs to be included in the meal plan.
Diabetes Food Pyramid
The Diabetes Food Pyramid divides food into six groups. These groups or sections on the pyramid vary in size. The largest group -- grains, beans, and starchy vegetables -- is on the bottom. This means that more servings of grains, beans, and starchy vegetables should be eaten than of any of the other foods. The smallest group -- fats, sweets, and alcohol -- is at the top of the pyramid. This serves as a reminder to eat very few servings from these food groups.

The Diabetes Food Pyramid gives a range of servings. If a person followed the minimum number of servings in each group, they would eat about 1600 calories and if they eat at the upper end of the range, it would be about 2800 calories. Most women, would eat at the lower end of the range and many men would eat in the middle to high end of the range if they are very active. The exact number of servings need depends on the diabetes goals, calorie and nutrition needs, lifestyle, and the foods they like to eat. Divide the number of servings they should eat among the meals and snacks they eat each day.
On April 19, 2005 the United States Department of Agriculture (USDA) released a new food guidance system replacing the former Food Guide Pyramid. The new system, called "MyPyramid," provides a set of tools based on caloric requirements to help Americans make healthy food choices.
However, the Diabetes Food Pyramid is a little different than the USDA Food Guide Pyramid because it groups foods based on their carbohydrate and protein content instead of their classification as a food. To have about the same carbohydrate content in each serving, the portion sizes are a little different too. For example: potatoes and other starchy vegetables in the grains, beans and starchy vegetables group can be eaten instead of the vegetables group. Cheese is in the meat group instead of the milk group. A serving of pasta or rice is 1/3 cup in the Diabetes Food Pyramid and ½ cup in the USDA pyramid. Fruit juice is ½ cup in the Diabetes Food Pyramid and ¾ cup in the USDA pyramid. This difference is to make the carbohydrate about the same in all the servings listed.
Following is a description of each group and the recommended range of servings of each group developed by the American Diabetes Association.23
1. Grains and Starches - At the base of the pyramid are bread, cereal, rice, and pasta. These foods contain mostly carbohydrates. The foods in this group are made mostly of grains, such as wheat, rye, and oats. Starchy vegetables like potatoes, peas, and corn also belong to this group, along with dry beans such as black eyed peas and pinto beans. Starchy vegetables and beans are in this group because they have about as much carbohydrate in one serving as a slice of bread. So, count them as carbohydrates for the meal plan.
Choose 6-11 servings per day. Remember, not many people would eat the maximum number of servings. Most people are toward the lower end of the range. Serving sizes are:
2. Vegetables - All vegetables are naturally low in fat and good choices to include often in meals or have them as a low calorie snack. Vegetables are full of vitamins, minerals and fiber. This group includes spinach, chicory, sorrel, Swiss chard, broccoli, cabbage, bok choy, brussels sprouts, cauliflower, and kale, carrots, tomatoes, cucumbers, and lettuce. Starchy vegetables such as potatoes, corn, peas, and lima beans are counted in the starch and grain group for diabetes meal planning.
Choose at least 3-5 servings per day. A serving is:
3. Fruit - The next layer of the pyramid is fruits, which also contain carbohydrates. They have plenty of vitamins, minerals, and fiber. This group includes blackberries, cantaloupe, strawberries, oranges, apples, bananas, peaches, pears, apricots, and grapes.
Choose 2-4 servings per day. A serving is:
4. Milk - Milk products contain a lot of protein and calcium as well as many other vitamins. Choose non-fat or low-fat dairy products for the great taste and nutrition without the saturated fat.
Choose 2-3 servings per day. A serving is:
5. Meat and Meat Substitutes - The meat group includes beef, chicken, turkey, fish, eggs, tofu, dried beans, cheese, cottage cheese and peanut butter. Meat and meat substitutes are great sources of protein and many vitamins and minerals. Choose from lean meats, poultry and fish and cut all the visible fat off meat. Keep portion sizes small. Three ounces is about the size of a deck of cards and only need 4-6 ounces are needed for the whole day
Choose 4-6 oz per day divided between meals. Equal to 1 oz of meat:
6. Fats, Sweets, and Alcohol
Things like potato chips, candy, cookies, cakes, crackers, and fried foods contain a lot of fat or sugar. They aren't as nutritious as vegetables or grains. Keep servings small and save them for a special treat!
Serving sizes include:
The National Institute of Health has developed the following Diabetes Food Planning Chart. This can be useful in determining the individuals daily quantity of foods required within each of the food groups.
Meal Plan Calories
The National Institutes of Health has developed the following recommend that meal plans based upon the following calorie targets.24
1,200 to 1,600 calories a day if they are:
1,600 to 2,000 calories a day if they are:
2,000 to 2,400 calories a day if they are:
Daily Meal Plan
The following chart was produced by the CDC to serve as personal guide for planning the meals and snacks for one day.
Exchange Meal Plan
Another way to plan meals is to use exchanges. This system divides types of foods into six exchange lists. The lists are very much like the groups used in the food pyramid: starch/bread, meat and meat substitutes, vegetables, fruit, milk, and fat. The serving sizes of the foods on each list have similar amounts of calories, protein, carbohydrate, and fat content. Any food on the list can be "exchanged" for any other food on the same list.
The exchange meal plan is a food program that balances the amounts of carbohydrate eaten each day. Althought carbohydrates (carbs) supply energy for the body, they also affect blood sugar more than any other nutrient. The main goal of this food plan is to balance insulin with the carbohydrates that are eaten. This plan helps them decide what type of food to eat, how much and when to eat.
It is easier to manage blood sugar if a consistent amount of carbohydrates are eaten at each meal. Carbohydrates come from the starch, milk, and fruit lists. Based on the daily calorie requirements, the exchanges can be determined at each meal. The meal plan helps set a consistent amount of carbohydrates as well as eat a variety of other healthy foods that are consumed with each meal. It will also make food choices that fit with the persons lifestyle, culture, likes and dislikes and goals.
For example, if they need 1500 calories a day, the exchange meal plan might look like this:25
The numbers tell how many items can be picked from each food list. Notice that the carbohydrates (starch, fruit, milk) are equal for breakfast, lunch, and dinner and that they are also included in snacks.
The following menu might be chosen based on the above plan.
The next day, they can choose a completely different menu using the exchange lists. For example, instead of having cereal, they could choose toast from the starch list.
Sugary foods (brownies, sugar, ice cream, cookies, and honey) are on a list called the "other carbohydrates" list. If they choose to eat a food from the "other carbohydrates" list, they can exchange it for a starch, fruit, or milk exchange. For example, they may plan to eat cereal, milk, a banana, and grapefruit juice for breakfast. If they want to add sugar to their cereal, they can trade one of the carbohydrate items from breakfast, such as the banana, for the sugar.
Examples of types of food in each exchange list are as follows:
Carbohydrates
Meats and Meat Substitutes
Meats are divided into very lean, lean, medium-fat, and high-fat meats. High-fat meats may raise the cholesterol level and increase the risk for heart disease.
Fats
Fats include oils, butter, nuts, bacon, cream cheese, and other fatty foods. A fat exchange is equal to 5 grams of fat and 45 calories. Fats are divided into three lists: monounsaturated fats, polyunsaturated fats, and saturated fats. Saturated fats are the "bad" fats that are linked with raising cholesterol levels and heart disease.
Free Foods
A free food contains less than 20 calories or less than 5 grams of carbohydrate per serving. If they eat 3 servings a day or less, they do not need to count these foods. Examples of free foods include sugar-free gelatin, diet soft drinks, catsup, soy sauce, and spices.
Combination Foods
Many foods are mixed together. A dietitian can help determine out how many exchanges to count for foods such as casseroles. For example, a cup of lasagna would equal 2 carbohydrate exchanges and 2 medium-fat meat exchanges.
Measuring Food
The CDC recommends that the food servings selected are the right size by using:
Also, the Nutrition Facts label on food packages tells how much of that food is in one serving.
Weigh or measure foods to make sure they eat the right amounts.
These tips will help choose the right serving sizes.

Section IX. Treatment for Diabetes
Treating Diabetes
Diabetes can lead to serious complications, such as blindness, kidney damage, cardiovascular disease, and lower-limb amputations, but people with diabetes can lower the occurrence of these and other diabetes complications by controlling blood glucose, blood pressure, and blood lipids.26
Diabetes by Diabetes Medication Status, United States, 1997-2006
From 1997 to 2006, the number of adults with diabetes only taking pill(s) and the number taking both insulin and pill(s) approximately doubled. In contrast, the number of adults only using insulin remained stable. In 2006, about 14 million adults with diabetes reported taking either pill(s), or insulin, or both medications and 2.7 million not taking any medication.
Age-Adjusted Percentage Using Any Diabetes Medication Among Adults with Diabetes
From 1997 to 2006, trends in the crude and age-adjusted percentage of adults with diabetes taking any medication (either pill(s) or insulin or both) were similar and showed little change. In 2006, of adults with diabetes took diabetes medication is 84%.
Percentage Using Any Diabetes Medication Among Adults with Diabetes by Age
From 1997 to 2006, adults with diabetes aged 18-44 years had a lower percentage of any diabetes medication use (either pill(s) or insulin or both) than the older age groups. During this time period, no consistent trend was observed within each age group. In 2006, about 72% of adults with diabetes aged 18-44 years took any diabetes medication for diabetes, followed by 85% of those aged 45-64 years, 89% of those aged 65-74 years, and 87% of those aged 75 years and older.
Age-Adjusted Percentage Using Any Diabetes Medication Among Adults with Diabetes, by Race/Ethnicity
From 1997 to 2006, no trend was observed within each race/ethnicity group for the age-adjusted percentage of any diabetes medication use (either pill(s) or insulin or both) among adults with diabetes. However, during this period, using any diabetes medication was highest among blacks. In 2006, the age-adjusted percentage of any diabetes medication use among adults with diabetes was about 78% for white, 84% for black and 79% for Hispanics.
Gestational Diabetes
Pregnant women who have never had diabetes before but who have high blood sugar (glucose) levels during pregnancy are said to have gestational diabetes. Gestational diabetes affects about 4% of all pregnant women - about 135,000 cases of gestational diabetes in the United States each year.
It is not known what causes gestational diabetes, but there are some clues. The placenta supports the baby as it grows. Hormones from the placenta help the baby develop. But these hormones also block the action of the mother's insulin in her body. This problem is called insulin resistance. Insulin resistance makes it hard for the mother's body to use insulin. She may need up to three times as much insulin.
Gestational diabetes starts when the body is not able to make and use all the insulin it needs for pregnancy. Without enough insulin, glucose cannot leave the blood and be changed to energy. Glucose builds up in the blood to high levels. This is called hyperglycemia.
Gestational diabetes affects the mother in late pregnancy, after the baby's body has been formed, but while the baby is busy growing. Because of this, gestational diabetes does not cause the kinds of birth defects sometimes seen in babies whose mothers had diabetes before pregnancy.
However, untreated or poorly controlled gestational diabetes can hurt the baby. The pancreas works overtime to produce insulin, but the insulin does not lower the blood glucose levels. Although insulin does not cross the placenta, glucose and other nutrients do. Extra blood glucose goes through the placenta, giving the baby high blood glucose levels. This causes the baby's pancreas to make extra insulin to get rid of the blood glucose. Since the baby is getting more energy than it needs to grow and develop, the extra energy is stored as fat.
This can lead to macrosomia, or a "fat" baby. Babies with macrosomia face health problems of their own, including damage to their shoulders during birth. Because of the extra insulin made by the baby's pancreas, newborns may have very low blood glucose levels at birth and are also at higher risk for breathing problems. Babies with excess insulin become children who are at risk for obesity and adults who are at risk for type 2 diabetes.
Treating gestational diabetes
Treatment for gestational diabetes aims to keep blood glucose levels equal to those of pregnant women who don't have gestational diabetes. Treatment for gestational diabetes always includes special meal plans and scheduled physical activity. It may also include daily blood glucose testing and insulin injections. Treatment for gestational diabetes helps lower the risk of a cesarean section birth that very large babies may require.
Gestational diabetes usually goes away after pregnancy, however the chances are 2 in 3 that it will return in future pregnancies. In a few women, however, pregnancy uncovers type 1 or type 2 diabetes. It is hard to tell whether these women have gestational diabetes or have just started showing their diabetes during pregnancy. These women will need to continue diabetes treatment after pregnancy.
Many women who have gestational diabetes go on to develop type 2 diabetes years later. There seems to be a link between the tendency to have gestational diabetes and type 2 diabetes. Gestational diabetes and type 2 diabetes both involve insulin resistance. Certain basic lifestyle changes may help prevent diabetes after gestational diabetes.
Pregnancy and Preexisting Diabetes
About 1 in 100 women of childbearing age has diabetes before pregnancy. Pregnancy is considered risky for women with diabetes because of the increased risk of miscarriage, stillbirth and birth defects. However, with good preconception care and careful monitoring of their blood sugar, most women with preexisting diabetes can look forward to healthy pregnancies and healthy babies.27
It is important for women with preexisting diabetes to see a health care provider before trying to get pregnaat and to establish good blood sugar control before, during and after pregnancy. Women who take oral medications to control blood sugar will need to switch to insulin before conceiving and during pregnancy. A multivitamin and folic acid before conception and during early pregnancy can help prevent serious birth defects of the brain and spinal cord.
Women with poorly controlled diabetes in the early weeks of pregnancy are two to four times more likely than women without diabetes to have a baby with a serious birth defect, such as a heart defect or a neural tube defect. They also have an increased risk of miscarriage and stillbirth as well as increased risk of having a very large baby (10 pounds or more), which makes vaginal delivery more difficult and puts the baby at risk for injuries during birth.
Diabetes Complementary and Alternative Medical Therapies
The National Center for Complementary and Alternative Medicine, part of the National Institutes of Health, defines complementary and alternative medicine as a "group of diverse medical and health care systems, practices, and products that are not presently considered to be part of conventional medicine."
Complementary medicine is used with conventional therapy, whereas alternative medicine is used instead of conventional medicine.
Some people with diabetes use complementary or alternative therapies to treat diabetes. Although some of these therapies may be effective, others can be ineffective or even harmful. Patients who use complementary and alternative medicine need to let their health care providers know what they are doing.
Some complementary and alternative medicine therapies are discussed below.28
Acupuncture - procedure in which a practitioner inserts needles into designated points on the skin. Some scientists believe that acupuncture triggers the release of the body's natural painkillers. Acupuncture has been shown to offer relief from chronic pain. Acupuncture is sometimes used by people with neuropathy, the painful nerve damage of diabetes.
Biofeedback - a technique that helps a person become more aware of and learn to deal with the body's response to pain. This alternative therapy emphasizes relaxation and stress-reduction techniques. Guided imagery is a relaxation technique that some professionals who use biofeedback do. With guided imagery, a person thinks of peaceful mental images, such as ocean waves. A person may also include the images of controlling or curing a chronic disease, such as diabetes. People using this technique believe their condition can be eased with these positive images.
Chromium - The benefit of added chromium for diabetes has been studied and debated for several years. Several studies report that chromium supplementation may improve diabetes control. Chromium is needed to make glucose tolerance factor, which helps insulin improve its action. Because of insufficient information on the use of chromium to treat diabetes, no recommendations for supplementation yet exist.
Ginseng - Several types of plants are referred to as ginseng but most studies of ginseng and diabetes have used American ginseng. Those studies have shown some glucose-lowering effects in fasting and post-prandial (after meal) blood glucose levels as well as in A1C levels (average blood glucose levels over a 3-month period). However, larger and more long-term studies are needed before general recommendations for use of ginseng can be made. Researchers also have determined that the amount of glucose-lowering compound in ginseng plants varies widely.
Magnesium - Although the relationship between magnesium and diabetes has been studied for decades, it is not yet fully understood. Studies suggest that a deficiency in magnesium may worsen blood glucose control in type 2 diabetes. Scientists believe that a deficiency of magnesium interrupts insulin secretion in the pancreas and increases insulin resistance in the body's tissues. Evidence suggests that a deficiency of magnesium may contribute to certain diabetes complications. A recent analysis showed that people with higher dietary intakes of magnesium (through consumption of whole grains, nuts, and green leafy vegetables) had a decreased risk of type 2 diabetes.
Vanadium - Vanadium is a compound found in tiny amounts in plants and animals. Early studies showed that vanadium normalized blood glucose levels in animals with type 1 and type 2 diabetes. A recent study found that when people with diabetes were given vanadium, they developed a modest increase in insulin sensitivity and were able to decrease their insulin requirements. Currently researchers want to understand how vanadium works in the body, discover potential side effects, and establish safe dosages.

Section X. Diabetes in Children and Adolescents
Children with Diabetes
Diabetes is one of the most common diseases in school-aged children. According to the National Diabetes Fact Sheet, about 186,300 young people in the US under age 20 had diabetes in 2007. This represents 0.2% of all people in this age group.291
Based on data from 2002-2003, the SEARCH for Diabetes in Youth study reported that approximately 15,000 US youth under 20 years of age are diagnosed annually with type 1 diabetes, while 3,700 are newly diagnosed with type 2 diabetes. Type 2 diabetes is rare in children younger than 10 years of age, regardless of race or ethnicity. After 10 years of age, type 2 diabetes becomes increasingly common, especially in minority populations, representing 14.9% of newly diagnosed cases of diabetes in non-Hispanic whites, 46.1% in Hispanic youth, 57.8% in African Americans, 69.7 % in Asian/Pacific Islanders, and 86.2% in American Indian youth.
Results from the 2005-2006 National Health and Nutrition Examination Survey (NHANES), using measured heights and weights, indicate that an estimated 16-17 percent of children and adolescents ages 2-19 years had a BMI greater than or equal to 95th percentile of the age- and sex-specific BMI- about double the number of two decades ago. Overweight in youth contributes to the increasing numbers of young people who have type 2 diabetes.
Type 1 Diabetes
Type 1 diabetes is an autoimmune disease in which the immune system destroys the insulin-producing beta cells of the pancreas that help regulate blood glucose levels. Type 1 diabetes mostly has an acute onset, with children and adolescents usually able to pinpoint when symptoms began. Onset can occur at any age, but it most often occurs in children and young adults.
Since the pancreas can no longer produce insulin, people with type 1 diabetes are required to take insulin daily, either by injection or via an insulin pump. Other methods to deliver insulin are being investigated. Children with type 1 diabetes are at risk for long-term complications (damage to the cardiovascular system, kidneys, eyes, nerves, blood vessels, skin, gums, and teeth).
Type 1 diabetes accounts for 5 to 10 percent of all diagnosed cases of diabetes, but is the leading cause of diabetes in children of all ages, and in those less than 10 years of age, type 1 accounts for almost all diabetes. A diabetes management plan for young people includes insulin therapy, self-monitoring of blood glucose, healthy eating, and physical activity. The plan is designed to ensure proper growth and prevention of hypoglycemia. New management strategies are helping children with type 1 diabetes live long and healthy lives.
Symptoms
The immunologic process that leads to type 1 diabetes can begin years before the symptoms of type 1 diabetes develop. Symptoms become apparent when most of the beta-cell population is destroyed and develop over a short period of time. Early symptoms, which are mainly due to hyperglycemia, include increased thirst and urination, constant hunger, weight loss, and blurred vision. Children also may feel very tired.
As insulin deficiency worsens, ketoacids (formed from the breakdown of fat) build up in the blood and are excreted in the urine and breath. They cause the feeling of shortness of breath and abdominal pain, vomiting and worsening dehydration. Elevation of blood glucose, acidosis and dehydration comprise the condition known as diabetic ketoacidosis or DKA. If diabetes is not diagnosed and treated with insulin at this point, the individual can lapse into a life-threatening diabetic coma. Often, children with vomiting are mistakenly diagnosed as having gastroenteritis. New-onset diabetes can be differentiated from a GI infection by the frequent urination that accompanies continued vomiting, as opposed to decreased urination due to dehydration if the vomiting is caused by a GI "bug."
Risk Factors
A combination of genetic and environmental factors put people at increased risk for type 1 diabetes. Researchers are working to identify these factors so that targeted treatments can be designed to stop the autoimmune process that destroys the pancreatic beta-cells.Type 2 Diabetes
The first stage in the development of type 2 diabetes is often insulin resistance, requiring increasing amounts of insulin to be produced by the pancreas to control blood glucose levels. Initially, the pancreas responds by producing more insulin, but after several years, insulin production may decrease and diabetes develops. Type 2 diabetes used to occur mainly in adults who were overweight and older than 40 years. Now, as more children and adolescents in the United States become overweight, obese and inactive, type 2 diabetes is occurring more often in young people. Type 2 diabetes is more common in certain racial and ethnic groups such as African Americans, American Indians, Hispanic/Latino Americans, and some Asian and Pacific Islander Americans. The increased incidence of type 2 diabetes in youth is a "first consequence" of the obesity epidemic among young people, and is a significant and growing public health problem.2 Overweight and obese children are at increased risk for developing type 2 diabetes during childhood, adolescence, and later in life.Symptoms
Type 2 diabetes usually develops slowly and insidiously in children. Symptoms may be similar to those of type 1 diabetes. A child or teen can feel very tired, thirsty, or nauseated and have to urinate often. Other symptoms may include weight loss, blurred vision, frequent infections, and slow healing of wounds or sores. Some children or adolescents with type 2 diabetes may show no symptoms at all when they are diagnosed, and others may present with vaginal yeast infection or burning on urination due to yeast infection. Some children may have extreme elevation of the blood glucose level associated with severe dehydration and coma. Therefore, it is important for health care providers to identify and test children or teens who are at high risk for the disease.
Maturity-onset Diabetes of the Young
Maturity-onset diabetes of the young (MODY), due to one of six gene defects, is a rare form of diabetes in children that is caused by a single gene defect that results in faulty insulin secretion. MODY is defined by its early onset (usually before age 25), absence of ketosis, and autosomal dominant inheritance.3 Thus, each child of a parent with MODY has a 50 percent chance of inheriting the same type of diabetes. MODY is thought to account for 2 to 5 percent of all cases of diabetes and often goes unrecognized.3 Treatment of MODY varies. Some children respond to diet therapy, exercise, and/or oral anti-diabetes medications that enhance insulin release. Others may require insulin therapy.
Secondary Diabetes
Diabetes can occur in children with other diseases such as cystic fibrosis or those using glucocorticoid drugs. These causes may account for one to five percent of all diagnosed cases of diabetes.
Prevalence of Diabetes in Youth
Diabetes is one of the most common diseases in school-aged children. According to the National Diabetes Fact Sheet, about 186,300 young people in the US under age 20 had diabetes in 2007. This represents 0.2% of all people in this age group.
Based on data from 2002-2003, the SEARCH for Diabetes in Youth study reported that approximately 15,000 US youth under 20 years of age are diagnosed annually with type 1 diabetes, while 3,700 are newly diagnosed with type 2 diabetes. Type 2 diabetes is rare in children younger than 10 years of age, regardless of race or ethnicity. After 10 years of age, type 2 diabetes becomes increasingly common, especially in minority populations, representing 14.9% of newly diagnosed cases of diabetes in non-Hispanic whites, 46.1% in Hispanic youth, 57.8% in African Americans, 69.7 % in Asian/Pacific Islanders, and 86.2% in American Indian youth.
Results from the 2005-2006 National Health and Nutrition Examination Survey (NHANES), using measured heights and weights, indicate that an estimated 16-17 percent of children and adolescents ages 2-19 years had a BMI greater than or equal to 95th percentile of the age- and sex-specific BMI- about double the number of two decades ago. Overweight in youth contributes to the increasing numbers of young people who have type 2 diabetes. The Centers for Disease Control and Prevention (CDC) BMI and growth curves calculate body fatness in children.30
Identifying and Testing Children with Diabetes
Type 1 diabetes
The rate of beta cell destruction in type 1 diabetes is quite variable -- rapid in some individuals (mainly infants and children) and slow in others (mainly older adolescents and adults). Children and adolescents may present with ketoacidosis as the first indication of type 1 diabetes. Others may have post-meal hyperglycemia, or modest fasting hyperglycemia that rapidly progresses to severe hyperglycemia and/or ketoacidosis in the presence of infection or other stress.
As type 1 diabetes is caused by immune destruction of the insulin-producing beta cells, antibodies against proteins in the islets are found in children and adolescents months to years before the onset of diabetes. The presence of these antibodies, GAD-65, ICA, IAA and IA-2, have formed the basis for trials predicting who will develop diabetes and for recruiting high risk children and adults for prevention trials. Individuals with high titer antibodies and those with more than one antibody are more likely to develop type 1 diabetes. In addition, young age and being a first degree relative of someone with type 1 diabetes place children at high risk. In general, 70 percent of people with new-onset diabetes will have a positive antibody if only one antibody is tested, whereas 90 percent will have at least one antibody when all four are measured.
Type 2 diabetes
Most children and adolescents diagnosed with type 2 diabetes are overweight or obese, insulin resistant, and have a family history of type 2 diabetes. They also may have physical signs of insulin resistance such as acanthosis nigricans. Diabetes complications such as microalbuminuria and the presence of cardiovascular risk factors such as abnormal cholesterol and high blood pressure have been observed among teenage Pima Indians7 and in other pediatric populations in the United States8-10 and are often present at disease onset.
Undiagnosed type 2 diabetes in children and adolescents may place these young people at early risk for cardiovascular disease; however, no data are available to define the scope of this problem. In adults, up to 25% of individuals who have type 2 diabetes are undiagnosed and at risk for microvascular and macrovascular complications of diabetes.11 It is important, therefore, for health care providers to consider testing for diabetes in high risk or symptomatic children. Note that adult screening programs identify more people with diabetes than do equivalent screening programs in youth.
Current testing criteria and diabetes risk factors to help identify type 2 diabetes in children before the onset of complications were developed in 2000 by the American Academy of Pediatrics and the American Diabetes Association.
Testing Criteria
Overweight (BMI 85th to 94th percentile) or obese (BMI >95th percentile) for age and gender; weight for height >85th percentile; or weight >120 percent of ideal for height
PLUSAny two of the following risk factors:
Clinical judgment should be used to perform testing in children and adolescents who do not meet the above criteria.
Treatment Strategies
The basic elements of type 1 diabetes management are insulin administration, nutrition management, physical activity, blood glucose testing, and the avoidance of hypoglycemia. Algorithms are used for insulin dosing based on blood glucose level and food intake.
Children receiving fixed insulin doses of intermediate- and rapid-acting insulins must have food given at the time of peak action of the insulin. Children receiving a long-acting insulin analogue or using an insulin pump receive a rapid-acting insulin analogue just before meals, with the amount of pre-meal insulin based on carbohydrate content of the meal using an insulin:carbohydrate ratio and a correction scale for hyperglycemia. Further adjustment of insulin or food intake may be made based on anticipation of special circumstances such as increased exercise and intercurrent illness. Children on these regimens are expected to check their blood glucose levels routinely before meals and at bedtime.
Management of type 2 diabetes involves nutrition management, increased physical activity, and blood glucose testing. If this is not sufficient to normalize blood glucose levels, glucose-lowering medication and/or insulin therapy are used as well. There are a variety of different diabetes medications, some that are taken orally, and some taken by injection (or via a subcutaneous pump), such as insulin. Youth with type 2 diabetes may take one or more different glucose-lowering medications. Glucose lowering medications differ by their mechanism of actions. Overall, they can enhance endogenous insulin secretion, inhibit excessive hepatic glucose production, enhance insulin sensitivity in muscle and adipose tissue, inhibit gastrointestinal carbohydrate absorption, delay gastric emptying, inhibit glucagon secretion, and enhance satiety. The most frequently used oral glucose-lowering medication in children and adolescents is metformin. Glimperide is also approved for children eight years of age and older. All aspects of the regimen are individualized.
There is no single recipe to manage diabetes that fits all children. Blood glucose targets, frequency of blood glucose testing, type, dose and frequency of insulin, use of insulin injections with a syringe or a pen or pump, use of oral glucose-lowering medication and details of nutrition management all may vary among individuals. The family and diabetes care team determine the regimen that best suits each child's individual characteristics and circumstances.
Blood Glucose Goals
To control diabetes and prevent complications, blood glucose levels in children with type 1 diabetes should be managed as indicated in Table 1. Families should work with their health care team to set target blood glucose levels appropriate for the child. Although there are no national recommendations for children with type 2 diabetes, it may be reasonable to use the values in the following table as a guide.
Optimal plasma blood glucose and A1C goals for type 1 diabetes by age group are:
* A lower goal (<7.0) is reasonable if it can be achieved without excessive hypoglycemia.
Key concepts in setting glycemic goals:
Diabetes treatment can sometimes cause blood glucose levels to drop too low, with resultant hypoglycemia. Taking too much insulin, missing a meal or snack, or strenuous exercising may cause hypoglycemia. In addition, hypoglycemia can occur when there has been no apparent cause. A child can become irritable, shaky, or confused. When blood glucose levels fall very low, loss of consciousness or seizures may develop.
When hypoglycemia is recognized, the child should drink or eat a concentrated sugar to quickly raise the blood glucose to greater than 70 mg/dl. Once the blood glucose is over 70 mg/dl, the child can eat food containing protein to maintain blood glucose levels in the normal range. Hypoglycemia occurring during the night should be treated with a concentrated sugar to achieve a BG of 80- 100 mg/dL before giving a protein-containing food. The concentrated sugar will cause resolution of symptoms quickly, avoiding over-treatment of "lows." If the child is unable to eat or drink, a glucose gel may be administered to the buccal mucosa of the cheek; however, in the face of an altered level of consciousness or if the child cannot cooperate, glucagon or IV glucose should be administered.
Glycemic goals may need to be modified to take into account the fact that most children younger than 6 or 7 years of age have a form of "hypoglycemic unawareness." They lack the cognitive capacity to recognize and respond to hypoglycemic symptoms and may be at greater risk for hypoglycemia.
Hyperglycemia
Causes of hyperglycemia include forgetting to take medications on time, eating too much, and getting too little exercise. Some episodes of hyperglycemia may occur without an apparent reason. Being ill also can raise blood glucose levels. Over time, hyperglycemia can cause damage to the eyes, kidneys, nerves, blood vessels, gums, and teeth. Sick-day management rules, including assessment for ketosis with every illness, must be established for children with type 1 diabetes. Families need to be taught what to do for vomiting and for ketosis to prevent severe hyperglycemia and ketoacidosis.Monitoring Complications and Reducing CVD Risk
The following recommendations are based on the American Diabetes Association's Standards of Medical Care.
Retinopathy
Although retinopathy most commonly occurs after the onset of puberty and after 5-10 years of diabetes duration, it has been reported in prepubertal children and with diabetes duration of only 1-2 years. Referrals should be made to eye care professionals with expertise in diabetic retinopathy, an understanding of the risk for retinopathy in the pediatric population, as well as experience in counseling the pediatric patient and family on the importance of early prevention/intervention. For children with type 1 diabetes, the first ophthalmologic examination should be obtained once the child is 10 years of age or older and has had diabetes for 3-5 years. In type 2 diabetes, the initial examination should be shortly after diagnosis. In type 1 and type 2 diabetes, annual routine follow-up is generally recommended. Less frequent examinations may be acceptable on the advice of an eye care professional.
Nephropathy
To reduce the risk and/or slow the progression of nephropathy, optimize glucose and blood pressure control. For children with type 1 diabetes, annual screening for microalbuminuria should be initiated once the child is 10 years of age and has had diabetes for 5 years. In type 2 diabetes, annual screening should be initiated at diagnosis. Screening may be done with a random spot urine sample analyzed for microalbumin-to-creatinine ratio. Confirmed, persistently elevated microalbumin levels should be treated with an ACE inhibitor, titrated to normalization of microalbumin excretion if possible.
Neuropathy
Although it is unclear whether foot examinations are important in children and adolescents, annual foot examinations are painless, inexpensive, and provide an opportunity for education about foot care. The risk for foot complications is increased in people who have had diabetes over 10 years.
Lipids</p>
In children older than 2 years of age with a family history of total cholesterol over 240 mg/dl, or a CVD event before age 55, or if family history is unknown, perform a lipid profile after diagnosis of diabetes and when glucose control has been established. If family history is not a concern, then perform a lipid profile at puberty. Based on data obtained from studies in adults, having diabetes is equivalent to having had a heart attack, making diabetes a key risk factor for future cardiovascular disease.
Pubertal children should have a lipid profile at the time of diagnosis after glucose control has been established. If lipid values fall within the accepted risk levels (LDL-cholesterol less than 100 mg/dl), repeat the lipid profile every 5 years.
The goal for LDL-cholesterol in children and adolescents with diabetes is less than 100 mg/dl (2.60 mmol/l). If the LDL-cholesterol is greater than 100 mg/dl, the child should be treated with an exercise plan and a Step 2 American Heart Association diet. If, after 6 months of diet and exercise, the LDL-cholesterol level remains above 160 mg/dl, pharmacologic agents should be given. If, the LDL-cholesterol is between 130 and 160 mg/dl, pharmacologic therapy should be considered. Statins are the agents of choice. Weight loss, increased physical activity, and improvement in glycemic control often result in improvements in lipid levels.
Blood pressure
Careful control of hypertension in children is critical. Hypertension in childhood is defined as an average systolic or diastolic blood pressure >95th percentile for age, sex, and height measured on at least three separate days.31
ACE inhibitors are the agents of choice for the treatment of hypertension in children with co-existing microalbuminuria. They have beneficial effects on slowing progression or preventing diabetic nephropathy.
Health Care Team
Because most newly diagnosed cases of type 1 diabetes occur in individuals younger than 18 years of age, and more children and teens are now getting type 2 diabetes, care of this group requires integration of diabetes management with the complicated physical and emotional growth needs of children, adolescents, and their families, as well as consideration of teens' emerging autonomy and independence.
Diabetes care for children and teens should be provided by a team that can deal with these special medical, educational, nutritional, and behavioral issues. The team usually consists of a physician, diabetes educator, dietitian, social worker or psychologist, along with the patient and family. Children should be seen by the team at diagnosis and in follow-up, as agreed upon by the primary care provider and the diabetes team. The following schedule of care is based on the American Diabetes Association's Standards of Medical Care.
At Diagnosis, establish the goals of care and required treatment. Begin diabetes self-management education about healthy eating habits, daily physical activity, and insulin/medication administration, and self-monitoring of blood glucose levels if appropriate. A solid educational base is needed so that the individual and family can become increasingly independent in self-management of diabetes. Diabetes educators play an important role in this aspect of management.
Most young people with diabetes are seen by the health care team every 3 months. At each visit, the following should be monitored or examined:
Annually:
*The first ophthalmologic examination should be obtained once the child is age 10 or older and has had type 1 diabetes for 3 to 5 years. For children with type 2 diabetes, the first examination should be shortly after diagnosis.
Helping Children and Adolescents Manage Diabetes
The health care professional team, in partnership with the young person with diabetes and parents or other caregivers, needs to develop a personal diabetes management plan and daily schedule. The plan helps the child or teen to follow a healthy meal plan, get regular physical activity, check blood glucose levels, take insulin or oral medication as prescribed, and manage hyperglycemia and hypoglycemia.
Follow a healthy meal plan
Young people with diabetes need to follow a meal plan developed by a registered dietitian, diabetes educator, or physician. For children with type 1 diabetes, the meal plan must ensure proper nutrition for growth. For children with type 2, the meal plan should outline appropriate changes in eating habits that lead to better energy balance and reduce or prevent obesity. A meal plan also helps keep blood glucose levels in the target range.
Children or adolescents and their families can learn how different types of food -- especially carbohydrates such as breads, pasta, and rice -- can affect blood glucose levels. Portion sizes, the right amount of calories for the child's age and activity level, and ideas for healthy food choices at meal and snack time also should be discussed, including reduction in soda and juice consumption. Family support for following the meal plan and setting up regular meal times is a key to success, especially if the child or teen is taking insulin.
Get regular physical activity
Children with diabetes need regular physical activity, ideally a total of 60 minutes each day. Physical activity helps to lower blood glucose levels and increase insulin sensitivity, especially in children and adolescents with type 2 diabetes. Physical activity is also a good way to help children control their weight. In children with type 1 diabetes, the most common problem encountered during physical activity is hypoglycemia. If possible, a child or a teen should check blood glucose levels before beginning a game or a sport. If blood glucose levels are too low, the child should not be physically active until the low blood glucose level has been treated.
For more information on helping children be physically active, visit the Weight-Control Information Network (WIN) of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). WIN offers a number of publications that address healthy eating and physical activity.Check blood glucose levels regularly
Young people with diabetes should know the acceptable range for their blood glucose. Children, particularly those using insulin, should check blood glucose values regularly with a blood glucose meter, preferably one with a built-in memory. A health care team member can teach the child or teen how to use a blood glucose meter properly and how often to use it. Children should keep a journal or other records such as downloaded computer files of their glucose meter results to discuss with their health care team. This information helps providers make any needed changes to the child's or teen's personal diabetes plan. Continuous glucose sensing systems are becoming more available.Continuous Glucose Sensing Systems
After many years of research, continuous glucose sensing systems are becoming available for young people and adults with type 1 diabetes. All continuous glucose sensing systems have the same basic components: a sensor that is placed underneath the skin, a small transmitter worn on the body that connects to the sensor, and a hand-held cell-phone sized receiver that displays the current glucose levels and trends. Some systems integrate the receiver into an insulin pump, thereby reducing the number of extra components that need to be carried.
By having more glucose values available, users are able to see trends and better understand the effects of different foods, exercise, stress, and illness. Receivers sound an alarm when the person's glucose level drops below or goes above a certain pre-set level and in some systems when the projected glucose level will be high or low in 10 or 20 minutes, giving users a chance to prevent low blood glucose with early treatment. As insurance companies begin to approve coverage for continuous glucose sensors, more and more young people with type 1 diabetes are likely to benefit from them.
Take all diabetes medication as prescribed
Parents, caregivers, school nurses, and others can help a child or teen learn how to take medications as prescribed. For type 1 diabetes, a child or teen takes insulin at prescribed times each day via multiple injections or an insulin pump. Some young people with type 2 diabetes need oral medication or insulin or both. In any case, it is important to stress that all medication should be balanced with food and activity every day.Special Issues
Diabetes presents unique issues for young people with the disease. Simple things, such as going to a birthday party, playing sports, or staying overnight with friends, need careful planning. Checking blood glucose, making correct food choices, and taking insulin or oral medication can make school-age children feel "different" from their classmates and this can be particularly bothersome for teens.
For any child or teen with diabetes, learning to cope with the disease is a big task. Dealing with a chronic illness such as diabetes may cause emotional and behavioral challenges, sometimes leading to depression. Talking to a social worker or psychologist may help young people and their families learn to adjust to the lifestyle changes needed to stay healthy.
Family Support
Managing diabetes in children and adolescents is most effective when the entire family gets involved. Diabetes education should involve family members. Families can be encouraged to share concerns with physicians, diabetes educators, dietitians, and other health care providers to get their help in the day-to-day management of diabetes. Extended family members, teachers, school nurses, counselors, coaches, day care providers, and other resources in the community can provide information, support, guidance, and help with coping skills. These individuals also may be knowledgeable about resources for health education, financial services, social services, mental health counseling, transportation, and home visits.
Diabetes is stressful for both the children and their families. Parents should be alert for signs of depression or eating disorders or insulin omission to lose weight and seek appropriate treatment. While all parents should talk to their children about avoiding tobacco, alcohol, and other drugs, this is particularly important for children with diabetes. Smoking and diabetes each independently increase the risk of cardiovascular disease and people with diabetes who smoke have a greatly increased risk of heart disease and circulatory problems. Binge drinking can cause hyperglycemia acutely, followed by an increased risk of hypoglycemia. The symptoms of intoxication are very similar to the symptoms of hypoglycemia, and thus, may result in delay of treatment of hypoglycemia with potentially disastrous consequences.
Transition to Independence
Children with diabetes--depending on their age and level of maturity--will learn to take over much of their care. Most school-age children can recognize symptoms of hypoglycemia and monitor blood glucose levels. They also participate in nutrition decisions. They often can give their own insulin injections but may not be able to draw up the dose accurately in a syringe until a developmental age of 11 to 12 years.
Adolescents often have the motor and cognitive skills to perform all diabetes-related tasks and determine insulin doses based on blood glucose levels and food intake. This is a time, however, when peer acceptance is important, risk-taking behaviors common, and rebellion against authority is part of teens' search for independence. Thus, adolescents must be supervised in their diabetes tasks and allowed gradual independence with the understanding that the independence will be continued only if they adhere to the diabetes regimen and succeed in maintaining reasonable metabolic control. During mid-adolescence, the family and health care team should stress to teens the importance of checking blood glucose levels prior to driving a car to avoid hypoglycemia while driving.
Diabetes at School
NDEP's School Guide educates and informs school personnel about diabetes, how it is managed, and how each member of the school staff can help meet the needs of students with the disease. School principals, administrators, nurses, teachers, coaches, bus drivers, health care, and lunchroom staff all play a role in helping students with diabetes succeed.
Several Federal and some state laws provide protections to children with disabilities, including diabetes. These laws help ensure that all students with diabetes are educated in a medically safe environment and have the same access to educational opportunities as their peers-in public and some private schools. Students with diabetes are entitled to accommodations and modifications necessary for them to stay healthy at school. Accommodations may need to be made in the classroom, with physical education, on field trips, and/or for after-school activities.
Written plans outlining each student's diabetes management help students, their families, school staff, and the student's health care providers know what is expected of them. These expectations should be laid out in written documents, such as a:
Diabetes Medical Management Plan, developed by the student's personal health care team and family Quick Reference Emergency Plan, which describes how to recognize hypoglycemia and hyperglycemia and what to do as soon as signs or symptoms of these conditions are observed Education plans, such as the Section 504 Plan or Individualized Education Program (IEP)
Care Plan or Individual Health Plan generated by the school nurse
The school nurse is the most appropriate person to coordinate care for students with diabetes. Each student with diabetes should have a written plan, developed by the school nurse, incorporating physician orders, parent requests, and tailored to the specific developmental, physical, cognitive, and skill ability of the child. The nurse will conduct a nursing assessment of the student and develop a nursing care plan, taking into consideration the child's cognitive, emotional, and physical status as well as the medical orders contained in the Diabetes Medical Management Plan. A team approach to developing the care plan, involving the student, parent, health care provider, key school personnel, and school nurse, is the most effective way to ensure safe and effective diabetes management during the school day.
The nursing care plan would also identify school employees assigned to provide care to an individual student, under the direction of the school nurse, when allowed by state nurse practice acts. The school nurse is responsible for training, monitoring, and supervising these school personnel. The school nurse will promote and encourage independence and self-care consistent with the student's ability, skill, maturity, and developmental level.
Camps and Support Groups
Local peer groups and camps for children and teens with diabetes can provide positive role models and group activities. Peer encouragement often helps children perform diabetes-related tasks that they had been afraid to do previously and encourages independence in diabetes management. Talking with other children who have diabetes helps young people feel less isolated and less alone in having to deal with the demands of diabetes. They have the opportunity to discuss issues they share in common that others in their peer group can't understand, and they can share solutions to problems that they have encountered. Often, these programs challenge children physically and teach them how to deal with increased exercise, reinforcing the fact that diabetes should not limit them in their ability to perform strenuous physical activity.32
Prevention Strategies for Type 2 Diabetes
For children and teens at risk, health care professionals can encourage, support, and educate the entire family to make lifestyle changes that may delay -- or lower the risk for -- the onset of type 2 diabetes. Such lifestyle changes include keeping at a healthy weight and staying active. New research findings will help determine effective ways to lower risk factors in high risk children.

Section XI. Diabetic Neuropathies Nerve Damage
Nerve Disorders
Diabetic neuropathies are a family of nerve disorders caused by diabetes. People with diabetes can, over time, have damage to nerves throughout the body. Neuropathies lead to numbness and sometimes pain and weakness in the hands, arms, feet, and legs. Problems may also occur in every organ system, including the digestive tract, heart, and sex organs. People with diabetes can develop nerve problems at any time, but the longer a person has diabetes, the greater the risk.
An estimated 50 percent of those with diabetes have some form of neuropathy, but not all with neuropathy have symptoms. The highest rates of neuropathy are among people who have had the disease for at least 25 years.
Diabetic neuropathy also appears to be more common in people who have had problems controlling their blood glucose levels, in those with high levels of blood fat and blood pressure, in overweight people, and in people over the age of 40. The most common type is peripheral neuropathy, also called distal symmetric neuropathy, which affects the arms and legs.
Causes
The causes are probably different for different varieties of diabetic neuropathy. Researchers are studying the effect of glucose on nerves to find out exactly how prolonged exposure to high glucose causes neuropathy. Nerve damage is likely due to a combination of factors:
Symptoms
Symptoms depend on the type of neuropathy and which nerves are affected. Some people have no symptoms at all. For others, numbness, tingling, or pain in the feet is often the first sign. A person can experience both pain and numbness. Often, symptoms are minor at first, and since most nerve damage occurs over several years, mild cases may go unnoticed for a long time. Symptoms may involve the sensory or motor nervous system, as well as the involuntary (autonomic) nervous system. In some people, mainly those with focal neuropathy, the onset of pain may be sudden and severe.
Symptoms may include:
In addition, the following symptoms are not due to neuropathy but nevertheless often accompany it:
Types of Diabetic Neuropathy
Diabetic neuropathies can be classified as peripheral, autonomic, proximal, and focal. Each affects different parts of the body in different ways.
Neuropathy affects the nerves throughout the body can this includes:
Peripheral Neuropathy
This type of neuropathy damages nerves in the arms and legs. The feet and legs are likely to be affected before the hands and arms. Many people with diabetes have signs of neuropathy upon examination but have no symptoms at all. Symptoms of peripheral neuropathy may include:
These symptoms are often worse at night.
Peripheral neuropathy may also cause muscle weakness and loss of reflexes, especially at the ankle, leading to changes in gait (walking). Foot deformities, such as hammertoes and the collapse of the midfoot, may occur. Blisters and sores may appear on numb areas of the foot because pressure or injury goes unnoticed. If foot injuries are not treated promptly, the infection may spread to the bone, and the foot may then have to be amputated. Some experts estimate that half of all such amputations are preventable if minor problems are caught and treated in time.
Autonomic Neuropathy
Autonomic neuropathy affects the nerves that control the heart, regulate blood pressure, and control blood glucose levels. It also affects other internal organs, causing problems with digestion, respiratory function, urination, sexual response, and vision. In addition, the system that restores blood glucose levels to normal after a hypoglycemic episode may be affected, resulting in loss of the warning signs of hypoglycemia such as sweating and palpitations.
Normally, symptoms such as shakiness occur as blood glucose levels drop below 70 mg/dL. In people with autonomic neuropathy, symptoms may not occur, making hypoglycemia difficult to recognize. However, other problems can also cause hypoglycemia unawareness so this does not always indicate nerve damage.
The heart and circulatory system are part of the cardiovascular system, which controls blood circulation. Damage to nerves in the cardiovascular system interferes with the body's ability to adjust blood pressure and heart rate. As a result, blood pressure may drop sharply after sitting or standing, causing a person to feel light-headed-or even to faint. Damage to the nerves that control heart rate can mean that it stays high, instead of rising and falling in response to normal body functions and exercise.
Digestive System - Nerve damage to the digestive system most commonly causes constipation. Damage can also cause the stomach to empty too slowly, a condition called gastroparesis. Severe gastroparesis can lead to persistent nausea and vomiting, bloating, and loss of appetite. Gastroparesis can make blood glucose levels fluctuate widely as well, due to abnormal food digestion.
Nerve damage to the esophagus may make swallowing difficult, while nerve damage to the bowels can cause constipation alternating with frequent, uncontrolled diarrhea, especially at night. Problems with the digestive system may lead to weight loss.
Urinary Tract and Sex Organs - Autonomic neuropathy most often affects the organs that control urination and sexual function. Nerve damage can prevent the bladder from emptying completely, allowing bacteria to grow in the bladder and kidneys and causing urinary tract infections. When the nerves of the bladder are damaged, urinary incontinence may result because a person may not be able to sense when the bladder is full or control the muscles that release urine.
Neuropathy can also gradually decrease sexual response in men and women, although the sex drive is unchanged. A man may be unable to have erections or may reach sexual climax without ejaculating normally. A woman may have difficulty with lubrication, arousal, or orgasm.
Sweat Glands - Autonomic neuropathy can affect the nerves that control sweating. When nerve damage prevents the sweat glands from working properly, the body cannot regulate its temperature properly. Nerve damage can also cause profuse sweating at night or while eating.
Eyes - Finally, autonomic neuropathy can affect the pupils of the eyes, making them less responsive to changes in light. As a result, a person may not be able to see well when the light is turned on in a dark room or may have trouble driving at night.
Proximal Neuropathy
Proximal neuropathy, sometimes called lumbosacral plexus neuropathy, femoral neuropathy, or diabetic amyotrophy, starts with pain in either the thighs, hips, buttocks, or legs, usually on one side of the body. This type of neuropathy is more common in those with type 2 diabetes and in older people. It causes weakness in the legs, manifested by an inability to go from a sitting to a standing position without help. Treatment for weakness or pain is usually needed. The length of the recovery period varies, depending on the type of nerve damage.
Focal Neuropathy
Occasionally, diabetic neuropathy appears suddenly and affects specific nerves, most often in the head, torso, or leg. Focal neuropathy may cause:
People with diabetes also tend to develop nerve compressions, also called entrapment syndromes. One of the most common is carpal tunnel syndrome, which causes numbness and tingling of the hand and sometimes muscle weakness or pain. Other nerves susceptible to entrapment may cause pain on the outside of the shin or the inside of the foot.
Preventing Diabetic Neuropathy
The best way to prevent neuropathy is to keep blood glucose levels as close to the normal range as possible and maintaining safe blood glucose levels protects nerves throughout the body.
Neuropathy is diagnosed on the basis of symptoms and a physical exam. During the exam, the doctor may check blood pressure and heart rate, muscle strength, reflexes, and sensitivity to position, vibration, temperature, or a light touch.
The doctor may also do other tests to help determine the type and extent of nerve damage.33
Treatment
The first step is to bring blood glucose levels within the normal range to prevent further nerve damage. Blood glucose monitoring, meal planning, exercise, and oral drugs or insulin injections are needed to control blood glucose levels. Although symptoms may get worse when blood glucose is first brought under control, over time, maintaining lower blood glucose levels helps lessen neuropathic symptoms. Importantly, good blood glucose control may also help prevent or delay the onset of further problems.
Additional treatment depends on the type of nerve problem and symptom, as described in the following sections.
People with neuropathy need to take special care of their feet. The nerves to the feet are the longest in the body and are the ones most often affected by neuropathy. Loss of sensation in the feet means that sores or injuries may not be noticed and may become ulcerated or infected. Circulation problems also increase the risk of foot ulcers.
More than half of all lower limb amputations in the United States occur in people with diabetes-86,000 amputations per year. Doctors estimate that nearly half of the amputations caused by neuropathy and poor circulation could have been prevented by careful foot care. The recommended steps to follow are:
Pain Relief
To relieve pain, burning, tingling, or numbness, the doctor may suggest aspirin, acetaminophen, or nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen. (People with renal disease should use NSAIDs only under a doctor's supervision.) A topical cream called capsaicin is another option. Tricyclic antidepressant medications such as amitriptyline, imipramine, and nortriptyline, or anticonvulsant medications such as carbamazepine or gabapentin may relieve pain in some people. Codeine may be prescribed for a short time to relieve severe pain. Also, mexiletine, used to regulate heartbeat, has been effective in treating pain in several clinical trials.
Other pain treatments include transcutaneous electronic nerve stimulation (TENS), which uses small amounts of electricity to block pain signals, as well as hypnosis, relaxation training, biofeedback, and acupuncture.
Walking regularly or using elastic stockings may also help leg pain.
Gastrointestinal Problems
To relieve mild symptoms of gastroparesis-indigestion, belching, nausea, or vomiting-doctors suggest eating small, frequent meals, avoiding fats, and eating less fiber. When symptoms are severe, the doctor may prescribe erythromycin to speed digestion, metoclopramide to speed digestion and help relieve nausea, or other drugs to help regulate digestion or reduce stomach acid secretion.
To relieve diarrhea or other bowel problems, the doctor may prescribe an antibiotic such as tetracycline, or other medications as appropriate.
Dizziness and Weakness
Sitting or standing slowly may help prevent the light-headedness, dizziness, or fainting associated with blood pressure and circulation problems. Raising the head of the bed or wearing elastic stockings may also help. Some people may benefit from increased salt in the diet and treatment with salt-retaining hormones. Others may benefit from high blood pressure medications. Physical therapy can help when muscle weakness or loss of coordination is a problem.
Urinary and Sexual Problems
To clear up a urinary tract infection, the doctor will probably prescribe an antibiotic. Drinking plenty of fluids will help prevent another infection. People who have incontinence should try to urinate at regular intervals (every 3 hours, for example) since they may not be able to tell when their bladder is full.
To treat erectile dysfunction in men, the doctor will first do tests to rule out a hormonal cause. Several methods are available to treat erectile dysfunction caused by neuropathy, including taking oral drugs, using a mechanical vacuum device, or injecting a drug called a vasodilator into the penis before sex. The vacuum and vasodilator raise blood flow to the penis, making it easier to have and maintain an erection. Another option is to surgically implant an inflatable or semirigid device in the penis. A constriction ring or penile sling may be helpful.
Vaginal lubricants may be useful for women when neuropathy causes vaginal dryness. To treat problems with arousal and orgasm, the doctor may refer the woman to a gynecologist.

Section XII. Glossary
The following Glossary was developed by the National Center for Chronic Disease Prevention and Health Promotion.
A1C-A test that sums up how much glucose has been sticking to part of the hemoglobin during the past 3-4 months. Hemoglobin is a substance in the red blood cells that supplies oxygen to the cells of the body.
ACE inhibitor-A type of drug used to lower blood pressure. Studies indicate that it may also help prevent or slow the progression of kidney disease in people with diabetes. ACE is an acronym for angiotensin-converting enzyme.
Autoimmune process-A process where the body's immune system attacks and destroys body tissue that it mistakes for foreign matter.
beta cells-Cells that make insulin. Beta cells are found in areas of the pancreas called the Islets of Langerhans.
bladder-A hollow organ that urine drains into from the kidneys. From the bladder, urine leaves the body.
blood glucose-The main sugar that the body makes from the food we eat. Glucose is carried through the bloodstream to provide energy to all of the body's living cells. The cells cannot use glucose without the help of insulin.
blood pressure-The force of the blood against the artery walls. Two levels of blood pressure are measured: the highest, or systolic, occurs when the heart pumps blood into the blood vessels, and the lowest, or diastolic, occurs when the heart rests.
blood sugar-See blood glucose.
calluses-Thick, hardened areas of the skin, generally on the foot, caused by friction or pressure. Calluses can lead to other problems, including serious infection and even gangrene.
carbohydrate-One of three main groups of foods in the diet that provide calories and energy. (Protein and fat are the others.) Carbohydrates are mainly sugars (simple carbohydrates) and starches (complex carbohydrates, found in bread, pasta, beans) that the body breaks down into glucose.
cholesterol-A substance similar to fat that is found in the blood, muscles, liver, brain, and other body tissues. The body produces and needs some cholesterol. However, too much cholesterol can make fats stick to the walls of the arteries and cause a disease that decreases or stops circulation.
corns-A thickening of the skin of the feet or hands, usually caused by pressure against the skin.
diabetes-The short name for the disease called diabetes mellitus. Diabetes results when the body cannot use blood glucose as energy because of having too little insulin or being unable to use insulin. See also type 1 diabetes, type 2 diabetes, and gestational diabetes.
diabetes pills-Pills or capsules that are taken by mouth to help lower the blood glucose level. These pills may work for people whose bodies are still making insulin.
diabetic eye disease-A disease of the small blood vessels of the retina of the eye in people with diabetes. In this disease, the vessels swell and leak liquid into the retina, blurring the vision and sometimes leading to blindness.
diabetic ketoacidosis-High blood glucose with the presence of ketones in the urine and bloodstream, often caused by taking too little insulin or during illness.
diabetic kidney disease-Damage to the cells or blood vessels of the kidney.
diabetic nerve damage-Damage to the nerves of a person with diabetes. Nerve damage may affect the feet and hands, as well as major organs.
dialysis-A method for removing waste from the blood when the kidneys can no longer do the job.
diphtheria-An acute, contagious disease that causes fever and problems for the heart and nervous system.
EKG-A test that measures the heart's action. Also called an electrocardiogram.
flu-An infection caused by the "flu" (short for "influenza") virus. The flu is a contagious viral illness that strikes quickly and severely. Signs include high fever, chills, body aches, runny nose, sore throat, and headache.
food exchanges-A way to help people stay on special food plans by letting them replace items from one food group with items from another group.
gestational diabetes-A type of diabetes that can occur in pregnant women who have not been known to have diabetes before. Although gestational diabetes usually subsides after pregnancy, many women who've had gestational diabetes develop type 2 diabetes later in life.
gingivitis-A swelling and soreness of the gums that, without treatment, can cause serious gum problems and disease.
glucagon-A hormone that raises the blood glucose level. When someone with diabetes has a very low blood glucose level, a glucagon injection can help raise the blood glucose quickly.
glucose-A sugar in our blood and a source of energy for our bodies.
heart attack-Damage to the heart muscle caused when the blood vessels supplying the muscle are blocked, such as when the blood vessels are clogged with fats (a condition sometimes called hardening of the arteries).
HDL (or high-density lipoprotein)-A combined protein and fatlike substance. Low in cholesterol, it usually passes freely through the arteries. Sometimes called "good cholesterol."
high blood glucose-A condition that occurs in people with diabetes when their blood glucose levels are too high. Symptoms include having to urinate often, being very thirsty, and losing weight.
high blood pressure-A condition where the blood circulates through the arteries with too much force. High blood pressure tires the heart, harms the arteries, and increases the risk of heart attack, stroke, and kidney problems.
hormone-A chemical that special cells in the body release to help other cells work. For example, insulin is a hormone made in the pancreas to help the body use glucose as energy.
hyperglycemia-See high blood glucose.
hypertension-See high blood pressure.
hypoglycemia-See low blood glucose.
immunization-Sometimes called vaccination; a shot or injection that protects a person from getting an illness by making the person "immune" to it.
impotence-A condition where the penis does not become or stay hard enough for sex. Some men who have had diabetes a long time become impotent if their nerves or blood vessels have become damaged.
influenza-See flu.
inject-To force a liquid into the body with a needle and syringe.
insulin-A hormone that helps the body use blood glucose for energy. The beta cells of the pancreas make insulin. When people with diabetes can't make enough insulin, they may have to inject it from another source.
insulin-dependent diabetes-See type 1 diabetes.
ketones-Chemical substances that the body makes when it doesn't have enough insulin in the blood. When ketones build up in the body for a long time, serious illness or coma can result.
kidneys-Twin organs found in the lower part of the back. The kidneys purify the blood of all waste and harmful material. They also control the level of some helpful chemical substances in the blood.
laser surgery-Surgery that uses a strong ray of special light, called a laser, to treat damaged parts of the body. Laser surgery can help treat some diabetic eye diseases.
low blood glucose-A condition that occurs in people with diabetes when their blood glucose levels are too low. Symptoms include feeling anxious or confused, feeling numb in the arms and hands, and shaking or feeling dizzy.
LDL (or low-density lipoprotein)-A combined protein and fatlike substance. Rich in cholesterol, it tends to stick to the walls in the arteries. Sometimes called "bad cholesterol."
meal plan-A guide to help people get the proper amount of calories, carbohydrates, proteins, and fats in their diet. See also food exchanges.
microalbumin-A protein found in blood plasma and urine. The presence of microalbumin in the urine can be a sign of kidney disease.
nephropathy-See diabetic kidney disease.
neuropathy-See diabetic nerve damage.
non-insulin-dependent diabetes-See type 2 diabetes.
pancreas-An organ in the body that makes insulin so that the body can use glucose for energy. The pancreas also makes enzymes that help the body digest food.
periodontitis-A gum disease in which the gums shrink away from the teeth. Without treatment, it can lead to tooth loss.
plaque-A film of mucus that traps bacteria on the surface of the teeth. Plaque can be removed with daily brushing and flossing of teeth.
pumice stone-A special foot care tool used to gently file calluses as instructed by the health care team.
retinopathy-See diabetic eye disease.
risk factors-Traits that make it more likely that a person will get an illness. For example, a risk factor for getting type 2 diabetes is having a family history of diabetes.
self-monitoring blood glucose-A way for people with diabetes to find out how much glucose is in their blood. A drop of blood from the fingertip is placed on a special coated strip of paper that "reads" (often through an electronic meter) the amount of glucose in the blood.
stroke-Damage to a part of the brain that happens when the blood vessels supplying that part are blocked, such as when the blood vessels are clogged with fats (a condition sometimes called hardening of the arteries).
support group-A group of people who share a similar problem or concern. The people in the group help one another by sharing experiences, knowledge, and information.
type 1 diabetes-A condition in which the pancreas makes so little insulin that the body can't use blood glucose as energy. Type 1 diabetes most often occurs in people younger than age 30 and must be controlled with daily insulin injections.
type 2 diabetes-A condition in which the body either makes too little insulin or can't use the insulin it makes to use blood glucose as energy. Type 2 diabetes most often occurs in people older than age 40 and can often be controlled through meal plans and physical activity plans. Some people with type 2 diabetes have to take diabetes pills or insulin.
ulcer-A break or deep sore in the skin. Germs can enter an ulcer and may be hard to heal.
urea-One of the chief waste products of the body. When the body breaks down food, it uses what it needs and throws the rest away as waste. The kidneys flush the waste from the body in the form of urea, which is in the urine.
vaccination-A shot given to protect against a disease.
vitrectomy-An operation to remove the blood that sometimes collects at the back of the eyes when a person has eye disease.
yeast infection-A vaginal infection that is usually caused by a fungus. Women who have this infection may feel itching, burning when urinating, and pain, and some women have a vaginal discharge. Yeast infections occur more frequently in women with diabetes.
