The mechanism of bariatric surgery generally involves restriction, malabsorption, or a combination of these two mechanisms. Restrictive procedures decrease the size of the stomach resulting in early satiety and reduced caloric intake. The restrictive operations include laparoscopic adjustable gastric band (LAGB) and vertical sleeve gastrectomy (VSG). In contrast, malabsorptive procedures bypass a large part of the small intestine decreasing the degree of absorption of nutrients. For more details please contact us! 7300333555.
