PURPOSE OF REVIEW: Bariatric surgery has emerged as a highly effective treatment for obesity and is increasingly recognized to have benefits for glycemic management in patients with pre-existing type 2 diabetes mellitus (T2DM), and for diabetes prevention. This article will review the efficacy and mechanisms of metabolic surgery for the treatment of T2DM. RECENT FINDINGS: Recent small randomized studies with 1-2 years of follow-up begin to provide level 1 data of the effects of surgical procedures compared to medical management on glycemic control. Physiology studies using sophisticated metabolic techniques to evaluate insulin secretion, action, and entero-endocrine changes in patients preoperatively and postoperatively have shed light on the mechanisms that lead to changes in glycemia observed after bariatric surgery. SUMMARY: Understanding the efficacy and physiologic effects of bariatric surgery on metabolism will help guide patient management in the context of a growing epidemic of obesity and T2DM, and may also ultimately enable us to develop less invasive but equally effective therapeutic strategies for weight loss and metabolic control.
