Bariatric Surgery

Weight-loss (Bariatric) surgery helps you lose weight and lowers your risk of medical problems & death risk associated with obesity. Bariatric surgery contributes to weight loss in two main ways:

Restriction. Surgery is used to physically limit the amount of food the stomach can hold, which limits the number of calories you can eat.

Malabsorption. Surgery is used to shorten or bypass part of the small intestine, which reduces the amount of calories and nutrients the body absorbs.


Four common types of weight-loss surgery are :

1. Roux-en-Y gastric bypass
2. Laparoscopic adjustable gastric banding
3. Sleeve gastrectomy
4. Duodenal switch with biliopancreatic diversion
