Bariatric surgery is a treatment option for patients with morbid obesity that helps induce weight loss by altering food digestion and absorption. There are several types of bariatric surgery procedures, including Roux-en-Y gastric bypass, laparoscopic adjustable gastric banding, biliopancreatic diversion, duodenal switch, and vertical banded gastroplasty. The benefits of bariatric surgery include improvements in health, quality of life, and significant weight loss.
