American Diabetes Association: What is prediabetes?

NIH Publication:  Insulin Resistance and Pre-diabetes

The latest medical research clearly confirms that the glycemic index (GI)—an easy-to-understand ranking of foods based on their effect on blood glucose levels—is vitally important for heart health and the prevention of the Metabolic Syndrome (aka Syndrome X and insulin resistance).

Did You Know?

... that the diabetes drug Glucophage (metformin), a biguanide, reduced the risk of diabetes in those with prediabetes but was less successful than simply losing weight and increasing activity? (NIH DPP Study) See our Lifestyles section to learn how you can improve your health without medication.

... that prediabetes increases your risk of getting type 2 diabetes and of having heart disease or a stroke?

... that prediabetes can be reversed without insulin or medication by losing a modest amount of weight and increasing your physical activity?  

... that an international expert committee of the American Diabetes Association recently redefined the criteria for prediabetes, lowering the blood sugar level cut-off point for pre-diabetes?

Approximately 20% more adults are now believed to have this condition and may develop diabetes within 10 years if they do not exercise or maintain a healthy weight.

Prediabetes: Impaired glucose tolerance and impaired fasting glucose

According to the NIH,, prediabetes is a term used to distinguish people who are at increased risk of developing diabetes. People with prediabetes have impaired fasting glucose (IFG) or impaired glucose tolerance (IGT). Some people may have both IFG and IGT.

IFG is a condition in which the fasting blood sugar level is elevated (100 to 125 milligrams per deciliter or mg/dL) after an overnight fast but is not high enough to be classified as diabetes.

IGT is a condition in which the blood sugar level is elevated (140 to 199 mg/dL) after a 2-hour oral glucose tolerance test, but is not high enough to be classified as diabetes.

In a cross-section of U.S. adults aged 40-74 years who were tested from 1988 to 1994, 33.8% had IFG, 15.4% had IGT, and 40.1% had prediabetes (IGT or IFG or both). Were these percentages applied to the 2000 U.S. population, about 35 million adults aged 40-74 would have IFG, 16 million would have IGT, and 41 million would have prediabetes.

Progression to diabetes among those with prediabetes is not inevitable. Studies suggest that weight loss and increased physical activity among people with prediabetes prevent or delay diabetes and may return blood glucose levels to normal.

People with prediabetes are already at increased risk for other adverse health outcomes such as heart disease and stroke.

DPP Study Information Links

Who participated in the DPP?   NIH's DPP Study consisted of 3,234 study participants that were overweight and had IGT, which are both well-recognized risk factors for the development of type 2 diabetes.

In addition, 45% of the study participants were from minority groups (African American, Hispanic American/Latino, Asian American or Pacific Islander, or American Indian) that are at increased risk of developing diabetes.
