This document summarizes a study on the effects of sleeve gastrectomy on type 2 diabetic obese patients. 63 patients underwent sleeve gastrectomy and were followed for an average of 24 months. Prior to surgery, most patients had well-controlled type 2 diabetes treated with oral medications. After surgery, patients experienced significant weight loss and 87% achieved remission of their diabetes as measured by normal fasting blood glucose and HbA1c levels. There were no deaths or need for reoperation. The study concludes that sleeve gastrectomy is a safe and effective treatment for obese patients with well-controlled type 2 diabetes.
