In this video, Dr. Suman Kirti, Endocrinologist, Holy Family Hospital, New Delhi will talk about impaired glucose intolerance. After giving a load of glucose of 75 grams during the oral glucose tolerance test (OGTT), if the diabetes is more than 200 mg/dl and the normal post-prandial blood glucose level is 140 mg/dl or less, then the value between 140 and 199 mg/dl is impaired glucose tolerance. The process in between the 140 and 199 is the impaired glucose tolerance.
