[Bariatric surgery and multidisciplinary treatment for obesity].

Bariatric surgery is one of the most effective treatment options for obesity. Compared with laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery has demonstrated more benefits and surgical risks. Bariatric surgery can result in the decreases in multiple gastrointestinal hormone levels, which can partially explain the mechanisms behind weight loss and resolution of diabetes after bariatric surgery. The management after bariatric surgery should be multidisciplinary and comprehensive, including dietary adjustment, physical exercise, behavioral intervention, and drug therapy.
