Bariatric Surgery

Bariatric surgery includes a variety of procedures performed on people who have obesity.

Four common types of weight-loss surgery are:

  • Roux-en-Y gastric bypass

Gastric bypass surgery refers to a surgical procedure in which the stomach is divided into a small upper pouch and a much larger lower “remnant” pouch and then the small intestine is rearranged to connect to both.

  • Laparoscopic adjustable gastric banding

Adjustable gastric banding (also known as “Lap Band” or “Realize band”) is considered by many to be the least invasive surgery for weight loss. The procedure involves placing an implant, a soft silicone ring with an expandable balloon in the center, around the top part of the stomach

  • Sleeve gastrectomy.

Sleeve gastrectomy is a surgical procedure that induces weight loss by restricting food intake. With this procedure, which is usually performed laparoscopically, the surgeon removes approximately 75 percent of the stomach. This results in the stomach taking on the shape of a tube or “sleeve” which holds much less food.

  • Duodenal switch with biliopancreatic diversion.

The duodenal switch (DS) procedure, also known as biliopancreatic diversion with duodenal switch (BPD-DS) or gastric reduction duodenal switch (GRDS), is a weight loss surgery procedure that is composed of a restrictive and a malabsorptive aspect.
