Does impaired glucose tolerance increase my risk of developing diabetes?

Impaired glucose tolerance (IGT) is a dangerous pre-diabetic condition. Reversing it with diet and exercise may prevent you from getting diabetes. IGT is a gray area between having normal blood glucose and having diabetes. If you have IGT, your pre-breakfast blood glucose values are slightly elevated, usually above 110 mg/dl. This level is not high enough to qualify for a diagnosis of diabetes, which is above 126 mg/dl. Although you don't have diabetes, 5% of people with IGT do develop diabetes every year. This means that if you have had IGT for five years, your chance of getting diabetes increases to about 25%.

People with IGT are usually overweight, don't get much exercise, and often have relatives who have type 2 diabetes. Most doctors believe that if people with IGT improve their health by losing weight and getting more exercise, their risk of developing diabetes will be much lower. Also, eating a low-fat and high-fiber diet may help. You should get your blood glucose level checked at least once a year and if it is high, go to work on getting it into the normal range and keeping it there.
