FREQUENCY OF IMPAIRED GLUCOSE TOLERANCE IN DIFFERENT GRADES OF OBESITY

Abstract

ABSTRACT Introduction Impaired glucose tolerance (IGT) is a pre-diabetic condition. It is defined as fasting glucose less than 7.0 mmol/l (25 were selected for this study. Oral glucose tolerance was done to see the relation of impaired glucose tolerance with respect to different grades of obesity which are obese-1 if body mass index is >25 but <30 and obese-2 if ≥ 30. 75g oral glucose was given after overnight fasting and blood sample taken before and after two hours. Results: The mean age of the patients was 37.8±7.8 years. There were 47 (31.3%) male patients and 103 (68.7%) female patients. The mean height of the patients was 1.6±0.1 meters. The mean weight of the patients was 80.4±14.2 kg. The mean body mass index of the patients was 31.7±3.1 kg/m2. There were 55 (36.7%) patients of grade I obesity and 95 (63.3%) patients of grade II obesity. There were 14 (9.3%) patients who had positive impaired glucose tolerance test and 136 (91.7%) patients had negative impaired glucose tolerance test. Conclusion: It is concluded from this study that frequency of impaired glucose tolerance is common in patients with different grades of obesity occurred in 9.3% of all cases.
