Background: Surgical Background: Impaired glucose tolerance is known precursor of type-2 diabetes mellitus and more prevalent in obese people, different studies have varied results and true prevalence is still debatable. Aims of this study  to investigate the prevalence of IGT in different grades of obesity.

Methods: Authors have studied100 patients with obesity Grade1 (BMI >25 kg/m2 but <30) and Grade2 (BMI >30 kg/m2) at Gandhi Medical College, Bhopal during April to June 2019. Complete physical examination and blood tests including fasting blood glucose and oral glucose tolerance test (OGTT) were done.

Results: Results shows that 16% male and 14% female subjects had IGT. Male of age more than 60yrs and female aged between 51 to 60 were more pre-diabetic. Males having weight 71 to 80 kg and female of 51-60 kg were more pre-diabetic. Subjects with grade 1 obesity, 6.12% male and 5.88% female had IGT. Similarly, in grade 2-obese subjects 10.20% males and 7.84% females had IGT.

Conclusion: IGT is more prevalent in grade-1 and grade-2 obese population and a strong indicator of diabetes.
