What are the other forms of impaired glucose metabolism (also called pre-diabetes)?
People with pre-diabetes, a state between “normal” and “diabetes,” are at risk for developing diabetes, heart attacks, and strokes. However, studies suggest that weight loss and increased physical activity can prevent or delay diabetes. There are two forms of pre-diabetes. Impaired Fasting Glucose A person has impaired fasting glucose (IFG) when fasting plasma glucose is 100 to 125 mg/dL. This level is higher than normal but less than the level indicating a diagnosis of diabetes. Impaired Glucose Tolerance Impaired glucose tolerance (IGT) means that blood glucose during the oral glucose tolerance test is higher than normal but not high enough for a diagnosis of diabetes. IGT is diagnosed when the glucose level is 140 to 199 mg/dL 2 hours after a person drinks a liquid containing 75 grams of glucose. About 35 million people ages 40 to 74 have impaired fasting glucose and 16 million have impaired glucose tolerance. Because some people have both conditions, the total number of U.S. adults
