Sleeve Gastrectomy

How it works to help you lose weight?

A sleeve gastrectomy is a restrictive procedure that limits the amount of food you can eat by reducing the size of your stomach. During this procedure a thin vertical sleeve of stomach is created using a stapling device. This sleeve will typically hold between 50 to 150 mL, and is about the size of a banana. The excised portion of the stomach is removed.

  • No postoperative adjustments are required.
  • In clinical studies patients lost an average of 55% of their excess weight.
