Diabetes - series
: What is pre-diabetes and how is it different from diabetes? Answer: Pre-diabetes is the state that occurs when a person's blood glucose levels are higher than normal but not high enough for a diagnosis of diabetes. About 11 percent of people with pre-diabetes in the Diabetes Prevention Program standard or control group developed type 2 diabetes each year during the average 3 years of follow-up. Other studies show that many people with pre-diabetes develop type 2 diabetes in 10 years. Question: Is pre-diabetes the same as Impaired Glucose Tolerance or Impaired Fasting Glucose? Answer: Yes. Doctors sometimes refer to this state of elevated blood glucose levels as Impaired Glucose Tolerance or Impaired Fasting Glucose (IGT/IFG), depending on which test was used to detect it. Question: Why does it need a new name? Has the condition changed? Answer: The condition has not changed, but what is known about it has. The new name is given for several reasons. Pre-diabetes is a clearer way of explaining what it means to have higher than normal blood glucose levels. It means you are likely to develop diabetes and may already be experiencing the adverse health effects of this serious condition. People with pre-diabetes are at higher risk of cardiovascular disease. People with pre-diabetes have a 1.5-fold risk of cardiovascular disease compared to people with normal blood glucose. People with diabetes have a 2- to 4-fold increased risk of cardiovascular disease. It is now known that people with pre-diabetes can delay or prevent the onset of type 2 diabetes through lifestyle changes. Question: How do I know if I have pre-diabetes? Answer: Doctors can use either the fasting plasma glucose test (FPG) or the oral glucose tolerance test (OGTT) to detect pre-diabetes. Both require a person to fast overnight. In the FPG test, a person's blood glucose is measured first thing in the morning before eating. In the OGTT, a person's blood glucose is checked after fasting and again 2 hours after drinking a glucose-rich drink. Question: How does the FPG test define diabetes and pre-diabetes? Answer: Normal fasting blood glucose is below 100 mg/dl. A person with pre-diabetes has a fasting blood glucose level between 100 and 125 mg/dl. If the blood glucose level rises to 126 mg/dl or above, a person has diabetes. Question: How does the OGTT define diabetes and pre-diabetes? Answer: In the OGTT, a person's blood glucose is measured after a fast and 2 hours after drinking a glucose-rich beverage. Normal blood glucose is below 140 mg/dl 2 hours after the drink. In pre-diabetes, the 2-hour blood glucose is 140 to 199 mg/dl. If the 2-hour blood glucose rises to 200 mg/dl or above, a person has diabetes. Question: Which test is better? Answer: According to the expert panel, either test is appropriate to identify pre-diabetes. Question: Why do I need to know if I have pre-diabetes? Answer: If you have pre-diabetes, you can and should do something about it. Studies have shown that people with pre-diabetes can prevent or delay the development of type 2 diabetes by up to 58 percent through changes to their lifestyle that include modest weight loss and regular exercise. The expert panel recommends that people with pre-diabetes reduce their weight by 5-10 percent and participate in some type of modest physical activity for 30 minutes daily. For some people with pre-diabetes, intervening early can actually turn back the clock and return elevated blood glucose levels to the normal range. Question: Will my insurance cover testing and treatment? Answer: Because all insurance plans are different, this is a difficult question to answer. However, Medicare and most insurance plans cover diabetes testing for people suspected of having diabetes. People at risk for diabetes are also at risk for pre-diabetes. Since the test is the same and the risk factors are the same for both conditions, a pre-diabetes test may be covered. It is best to consult your physician and health insurance representative with specific coverage questions. Question: What is the treatment for pre-diabetes? Answer: Treatment consists of losing a modest amount of weight (5-10 percent of total body weight) through diet and moderate exercise, such as walking, 30 minutes a day, 5 days a week. Don't worry if you can't get to your ideal body weight. A loss of just 10 to 15 pounds can make a huge difference. If you have pre-diabetes, you are at a 50 percent increased risk for heart disease or stroke, so your doctor may wish to treat or counsel you about cardiovascular risk factors, such as tobacco use, high blood pressure, and high cholesterol. Question: Who should get tested for pre-diabetes? Answer: If you are overweight and age 45 or older, you should be checked for pre-diabetes during your next routine medical office visit. If your weight is normal and you're over age 45, you should ask your doctor during a routine office visit if testing is appropriate. For adults younger than 45 and overweight, your doctor may recommend testing if you have any other risk factors for diabetes or pre-diabetes. These include high blood pressure, low HDL cholesterol and high triglycerides, a family history of diabetes, a history of gestational diabetes or giving birth to a baby weighing more than 9 pounds, or belonging to an ethnic or minority group at high risk for diabetes. Question: How often should I be tested? Answer: If your blood glucose levels are in the normal range, it is reasonable to be checked every 3 years. If you have pre-diabetes, you should be checked for type 2 diabetes every 1-2 years after your diagnosis. Question: Could I have pre-diabetes and not know it? Answer: Yes, people with pre-diabetes don't often have symptoms. In fact, millions of people have diabetes and don't know it because symptoms develop so gradually, people often don't recognize them. Some people have no symptoms at all. Symptoms of diabetes include unusual thirst, a frequent desire to urinate, blurred vision, or a feeling of being tired most of the time for no apparent reason. Question: Should children be screened for pre-diabetes? Answer: It is not recommended to screen children at this time for pre-diabetes because there isn’t enough evidence that type 2 diabetes can be prevented or delayed in children at high risk for the disease. However, a stu
Answer: You are correct in that more and more and more people are suffering from diabetes than ever before. This is caused by several things, not the least of which is our diet. Because this problem is so prevalent, I would be happy to furnish a series of questions and answers on “pre-diabetes” and then on the disease itself, over the next several issues.

Question: Should children be screened for pre-diabetes? Answer: It is not recommended to screen children at this time for pre-diabetes because there isn’t enough evidence that type 2 diabetes can be prevented or delayed in children at high risk for the disease. However, a study published a few years ago in the New England Journal of Medicine found 25 percent of very obese children and 21 percent of very obese adolescents had pre-diabetes. If future studies show that early intervention also works for children, a recommendation could be forthcoming.
