Abstract
The incidence of type 2 diabetes (T2D) is increasing at an alarming rate worldwide. Bariatric surgical procedures, such as the vertical sleeve gastrectomy and Roux-en-Y gastric bypass, are the most efficient approaches to obtain substantial and durable remission of T2D. The benefits of bariatric surgery are realized through the consequent increased satiety and alterations in gastrointestinal hormones, bile acids, and the intestinal microbiota. A comprehensive understanding of the mechanisms by which various bariatric surgical procedures exert their benefits on T2D could contribute to the design of better non-surgical treatments for T2D. In this review, we describe the classification and evolution of bariatric surgery and explore the multiple mechanisms underlying the effect of bariatric surgery on insulin resistance. Based upon our summarization of the current knowledge on the underlying mechanisms, we speculate that the gut might act as a new target for improving T2D. Our ultimate goal with this review is to provide a better understanding of T2D pathophysiology in order to support development of T2D treatments that are less invasive and more scalable.
Core Tip: Bariatric surgery is an effective treatment for type 2 diabetes (T2D), providing long-term remission. Among these types of weight loss procedures, the vertical sleeve gastrectomy and Roux-en-Y gastric bypass are extensively performed worldwide, but in the United States especially. Through establishment of reduced caloric intake and alterations in gut hormones, bile acids, and intestinal microbes, these procedures also contribute to the resolution of T2D. Understanding the mechanisms underlying the effects of bariatric surgery on T2D might provide new targets for more effective non-surgical treatments, such as medications, for T2D.
