Types of Bariatric Surgery

The main types of bariatric surgery are:

  • Sleeve gastrectomy, also known as gastric sleeve surgery, is a restrictive procedure that limits the amount of food you eat by reducing the size of your stomach. Unlike gastric bypass surgery, a sleeve gastrectomy does not involve any surgery on the intestine. During the gastric sleeve procedure, a thin vertical sleeve of stomach is created using a stapling device. This sleeve typically holds between 50-100 ml, about the size of a banana. After the separation of the stomach into a smaller tube, the remainder of the stomach is removed. The valve at the outlet of the stomach remains, allowing the normal process of stomach emptying to continue, which allows for a quicker feeling of fullness when eating. In the gastric sleeve procedure, there are no new connections made between the stomach and small intestine.

    Because sleeve gastrectomy involves the removal of a portion of the stomach, the procedure is permanent.


  • Laparoscopic Roux-en-Y Gastric Bypass Surgery, which permanently changes the size of your stomach and redirects part of your small intestines to a new, smaller pouch.
