This document discusses bariatric surgery as a treatment for diabetes. It notes that 240 million people worldwide currently have diabetes, a number expected to rise to 380 million by 2025. Bariatric surgeries like gastric banding, sleeve gastrectomy, and gastric bypass can result in significant and sustained weight loss, leading to remission of type 2 diabetes in 80% of patients. Both short-term changes in gut hormones and long-term changes in adipose tissue and adipokines contribute to improved glucose control after weight loss surgery. The author has received training in bariatric procedures and now regularly performs sleeve gastrectomies at their hospital to treat diabetes.
