Type-2 diabetes mellitus has increased exponentially in urban populations and that even the underprivileged are not exempt. Changing societal structures and lifestyles are accelerating it. Proximate causes for this epidemic are excessive consumption of calories and declining physical activity, which leads to increasing in obesity, especially central obesity. Material & Methods: Across sectional study was conducted from October 2010 to October 2012. Macrovascular and microvascular complications prevalence were compared in 3 subgroups based on BMI. 120 cases were studied. Results: Out of 120 patients 88 (73.33%) are male and 32 (26.66%) are female. Most common age period in which prevalence of diabetes found in each sub groups is 40-59years.In obese patients, 20( 50%) are hypertensive and out of them 12 (30%) and 8(20%) are in JNC Class 1 and 2 respectively. Obese patients with macrovascular complications(hypertension,IHD,CV stroke) are more as compared to those of lean and IBW groups. More than half 64 (53.33%) study population reported with peripheral Neuropathy. Near about half 56(46.7%) reported with retinopathy. Conclusion: Microvascular complications like peripheral neuropathy, Retinopathy are most common and independently associated with NIDDM. Microvascular complications are much higher than macrovascular complications in Type 2 DM-lean(BMI <18.5).
