What is Pre-Diabetes?
Before people develop type 2 diabetes, they almost always have "pre-diabetes" -- blood glucose levels that are higher than normal but not yet high enough to be diagnosed as diabetes. There are 41 million people in the United States, ages 40 to 74, who have pre-diabetes. Recent research has shown that some long-term damage to the body, especially the heart and circulatory system, may already be occurring during pre-diabetes.
Research has also shown that if you take action to manage your blood glucose when you have pre-diabetes, you can delay or prevent type 2 diabetes from ever developing. Together with the National Institute of Diabetes and Digestive and Kidney Diseases, the American Diabetes Association published a Position Statement on "The Prevention or Delay of Type 2 Diabetes" to help guide health care professionals in treating their patients with pre-diabetes.
There is a lot you can do yourself to know your risks for pre-diabetes and to take action to prevent diabetes if you have, or are at risk for, pre-diabetes. The American Diabetes Association has a wealth of resources for people with diabetes. People with pre-diabetes can expect to benefit from much of the same advice for good nutrition and physical activity. The links on this page are cornerstones of successful management of pre-diabetes.

How to Prevent Pre-Diabetes
Pre-diabetes is a serious medical condition that can be treated. The good news is that the recently completed Diabetes Prevention Program study conclusively showed that people with pre-diabetes can prevent the development of type 2 diabetes by making changes in their diet and increasing their level of physical activity.

Common Concerns
In this section, learn more about common concerns that people with diabetes face every day. These include what happens when you're sick, and when you travel, should you get a flu/pneumonia shot, and dealing with feelings like anger and depression.
Diabetes Learning Center
It's essential for people with diabetes to take care of themselves. To help you take the first steps toward better diabetes care, we have created the Diabetes Learning Center, an area for people who are newly diagnosed with diabetes, or those needing basic information.

Insulin Resistance and Pre-Diabetes
Insulin resistance is a silent condition that increases the chances of developing diabetes and heart disease. Learning about insulin resistance is the first step you can take toward making lifestyle changes that will help you prevent diabetes and other health problems.
What does insulin do?
After you eat, the food is broken down into glucose, the simple sugar that is the main source of energy for the body's cells. But your cells cannot use glucose without insulin, a hormone produced by the pancreas. Insulin helps the cells take in glucose and convert it to energy. When the pancreas does not make enough insulin or the body is unable to use the insulin that is present, the cells cannot use glucose. Excess glucose builds up in the bloodstream, setting the stage for diabetes.
Being obese or overweight affects the way insulin works in your body. Extra fat tissue can make your body resistant to the action of insulin, but exercise helps insulin work well.
How are insulin resistance, pre-diabetes, and type 2 diabetes linked?
If you have insulin resistance, your muscle, fat, and liver cells do not use insulin properly. The pancreas tries to keep up with the demand for insulin by producing more. Eventually, the pancreas cannot keep up with the body's need for insulin, and excess glucose builds up in the bloodstream. Many people with insulin resistance have high levels of blood glucose and high levels of insulin circulating in their blood at the same time.
People with blood glucose levels that are higher than normal but not yet in the diabetic range have "pre-diabetes." Doctors sometimes call this condition impaired fasting glucose (IFG) or impaired glucose tolerance (IGT), depending on the test used to diagnose it. In a cross-section of U.S. adults aged 40 to 74 tested during the period 1988 to 1994, 33.8 percent had IFG, 15.4 percent had IGT, and 40.1 percent had pre-diabetes (IGT or IFG or both). Applying these percentages to the 2000 U.S. population, about 35 million adults aged 40 to 74 would have IFG, 16 million would have IGT, and 41 million would have pre-diabetes.
If you have pre-diabetes, you have a higher risk of developing type 2 diabetes, formerly called adult-onset diabetes or noninsulin-dependent diabetes. Studies have shown that most people with pre-diabetes go on to develop type 2 diabetes within 10 years, unless they lose 5 to 7 percent of their body weight--which is about 10 to 15 pounds for someone who weighs 200 pounds--by making modest changes in their diet and level of physical activity. People with pre-diabetes also have a higher risk of heart disease.
Type 2 diabetes is sometimes defined as the form of diabetes that develops when the body does not respond properly to insulin, as opposed to type 1 diabetes, in which the pancreas makes no insulin at all. At first, the pancreas keeps up with the added demand by producing more insulin. In time, however, it loses the ability to secrete enough insulin in response to meals.
Insulin resistance can also occur in people who have type 1 diabetes, especially if they are overweight.
