Gastric Bypass Surgery Regulates Glucose Homeostasis Through the Hypothalamus

Abstract

To explore the role of blood glucose regulation in gastric bypass surgery is a hot point in the treatment of diabetes in recent years. Current evidence is very clear that the gastric bypass surgery is one of the most promising therapy to cure type 2 diabetes. However, the mechanisms are not yet understood. Studying the mechanism of surgical treatment can not only understand the pathogenesis of diabetes, but also have important scientific and practical significance for clinically and safely carrying out this therapy. As is known to all, the body's energy metabolism and glucose homeostasis are regulated by the hypothalamus. Thus, we summarize the process mechanism of central regulation of glucose homeostasis in post-surgery and find that the hypothalamus after gastric bypass surgery showed enhanced expression of peripheral signal receptors, enhancement of leptin signal and insulin signal, and expression changes of certain related genes, then issued neuroendocrine signals to control peripheral insulin sensitivity and glucose metabolism. Then, we prove that the improvement of peripheral metabolic status is caused by the decisive role of central regulation in post-surgery. These funding provide scientific basis to improve the understanding of the neuroendocrine mechanism of diabetes and the development of clinical implication of gastric bypass surgery.
