Pre-diabetes occurs in those individuals with blood glucose levels that are higher than normal but not high enough for a diabetes diagnosis.

This condition raises the risk of developing type 2 diabetes, stroke, and heart disease. In fact, people with diabetes are 2 to 4 times more likely than non-diabetic people to develop heart disease.

Pre-diabetes is also called impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or insulin resistance. Some people have both IFG and IGT. In IFG, glucose levels are a little high several hours after a person eats. In IGT, glucose levels are a little higher than normal right after eating.

Pre-diabetes is becoming more common in the U.S., according to estimates provided by the U.S. Department of Health and Human Services (DHHS). Many individuals with pre-diabetes go on to develop type 2 diabetes within 10 years. (See Diabetes)
