The effect of bariatric surgery on gut hormones that alter appetite

Abstract

Bariatric surgery is the only effective treatment for morbid obesity in the long term. Gut hormones are key players in the metabolic mechanisms causing obesity. Furthermore gut hormones are involved in the signalling process of hunger and satiety which leads to the control of nutrient intake. In this review, the role of these hormones as facilitators of appetite control after bariatric and metabolic surgery will be explored.
