Impaired Glucose Tolerance
People with Impaired Glucose Tolerance (IGT) have blood glucose levels that are higher than normal but not yet diabetic. This condition is diagnosed using the oral glucose tolerance test (OGTT). After a fast of 8 to12 hours, a person's blood glucose is measured before and 2 hours after drinking a glucose-containing solution.
As few as 1 to as many as 10 of every 100 persons with IGT will develop diabetes per year. The risk of getting diabetes rises as people become more overweight and more sedentary, have a stronger family history of diabetes, and belong to a racial or ethnic minority group.
