How vertical sleeve gastrectomy works

Over the years, sleeve gastrectomy has emerged as the most sought-after bariatric procedure worldwide. Gastric sleeve benefits far outweigh the potential gastric sleeve risks, which encourages many patients to choose this surgery over various other weight loss procedures.  

How Gastric Sleeve Works?

Before we look at the pros and cons of gastric sleeve, let us understand how this surgery works. Your weight loss surgeon will perform this procedure in two steps. 

  • In the first step, the surgeon will remove a substantial part of your stomach (nearly three-quarters) along the external curvature. When the food pouch is made smaller, you will naturally eat less and lose weight.
  • In the second step, they will give the new stomach a shape of a slender tube or a “sleeve” (hence the name “gastric sleeve”). The surgeon will not make any change to the normal outlet (the pyloric valve) that regulates the release of food from the stomach pouch to the small intestine.  

The procedure will not only reduce your appetite, but also allow for a lower absorption of calories in your body, which further promotes weight loss. Certain favorable hormonal changes will also occur in the body with this surgery, which will help you curb hunger and achieve sustainable weight loss.
