What are the long-term effects of bariatric surgery on weight loss in adults?
According to a 2017 meta-analysis of studies on the long- and very long-term effects of laparoscopic adjustable gastric banding, laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy on weight loss in adults, bariatric surgery is associated with long-term weight loss. However, the amount of weight lost varies depending on the type of procedure, with sleeve gastrectomy resulting in the greatest amount of sustained weight loss. Additionally, the study found that those who underwent gastric bypass surgery experienced greater improvements in comorbidities than those who underwent other types of bariatric surgery.
