Long-term outcomes of bariatric surgery in patients with diabetes

Introduction: Initially seen as a weight-loss operation, bariatric surgery is now recognized as a metabolic procedure with a critical role in the management of type 2 diabetes mellitus (T2DM). Early improvement in glucose metabolism is a remarkable effect of surgery; however, what deserves equal thought are implications for long-term diabetes control and relapse. Evidence suggests the metabolic effects of surgery fatigue and a proportion of patients will experience relapse of T2DM, with or without weight regain. Herein, we discuss the evidence examining the durability of these effects and approaches to improve long-term control.Areas covered: PubMed, Embase, CENTRAL, and Medline were searched for trials looking at outcomes for patients with obesity and T2DM undergoing bariatric surgery between January 2000 andDecember 2019. Additional studies were found by searching publications from related journals and references.Export opinion: Bariatric surgery is a safe and effective treatment for T2DM and obesity however the response to surgery, like any other treatment is variable. Some patients will experience a relapse of diabetes in the long term. Recent developments in pharmacotherapy present an opportunity to augment or sustain what can be achieved with surgery. Combinational treatment may dramatically change the way both diseases are managed.
