Introduction: Sleeve Gastrectomy has become popular as a standalone procedure, but its usefulness as an efficacious metabolic procedure for glycemic control and remission of diabetes is still under investigation. Many studies have shown benefits following LSG, although its long-term efficacy both as a bariatric and a metabolic procedure is yet to be established. This study was carried out to have a comprehensive picture of the effects on various parameters following LSG in obese populations with T2DM in the Indian scenario. Aim: The effect of Laparoscopic Sleeve Gastrectomy (LSG) on the usage of medications and measurable change in glycemic control as seen by changes in Blood sugar, HbA1c, insulin & Homeostatic model assessment of insulin resistance (HOMA-IR) levels Material and methods: All the patients with BMI > 32.5 kg/ m2 with type 2 diabetes mellitus undergoing Laparoscopic Sleeve Gastrectomy were included in the study. The period of the study was from Oct. 2017 to Mar. 2019. Blood sugar (fasting and postprandial) and insulin levels were checked before the surgery, 3 months, and 6 months after the surgery. We also recorded BMI and HOMA-IR levels. Statistical analysis: Statistical analysis was carried out using SPSS 21.0. Results: Out of 51 patients, 18 were males and 33 were females. The mean age of the patients was 42.26 ± 10.3 years. The mean BMI was 41.74 ± 4.28 kg/m2. 68.63% (35) stopped the medication and 31.37% (16) continued the medication after the surgery. The insulin, blood sugar levels (fasting and postprandial), HbA1c, BMI and HOMA-IR values decreased after the surgery. Conclusion: LSG results in an improvement in glycemic control and achieving remission in most of the diabetic patients
