Bariatric Surgery


Bariatric surgery is a weight loss surgery which includes a many procedures performed on obese people. The size of the stomach is reduced with a gastric band or a portion of the stomach is removed (sleeve gastrectomy or biliopancreatic diversion with duodenal switch) or by re-routing the small intestine to a small stomach pouch (gastric bypass surgery).

Types of Bariatric Surgey:

  1. Lap Band Surgery: At the top part of the stomach an adjustable ring is put to create a small pouch that increases the time food remains in the top part of the stomach.
  2. Gastric Bypass: Some of the small intestine is removed and a small pouch is created by stapling. It is directly joined to the small intestine and the food bypasses most of the stomach and fewer calories are absorbed.
  3. Gastric Sleeve Surgery: Most of the stomach is removed which includes the hormones required for hunger.
