Changes in gut hormones after bariatric surgery.
Bariatric surgery is one of the most effective treatments for achieving long-term weight loss in morbidly obese patients. Bariatric surgery causes weight loss through substantial decline of hunger and increased satiety. Recently our understanding of neuroendocrine regulation of food intake and weight gain, especially regarding the role of gut hormones, has significantly increased. The changes in these hormones following bariatric surgery can partly explain the mechanism behind weight loss achieved through these procedures. In this paper, we review the effect bariatric procedures have on different gut hormone levels and how they in turn can alter the complex neuroendocrine regulation of energy homeostasis.
