Sleeve Gastrectomy

What is sleeve gastrectomy surgery?

Gastric sleeve surgery, also called sleeve gastrectomy, is a bariatric surgery procedure. It removes a large portion of your stomach, leaving behind a narrow “sleeve.” Reducing your stomach helps restrict calories and reduce hunger signals.

In a sleeve gastrectomy, part of the stomach is separated and removed from the body. The remaining section of the stomach is formed into a tubelike structure. This smaller stomach cannot hold as much food. It also produces less of the appetite-regulating hormone ghrelin, which may lessen your desire to eat.
