Gastric Sleeve Surgery

Gastric sleeve surgery reduces the size of your stomach, restricting how much you can eat. As a result, you feel full quickly and eat less. Your body continues to absorb nutrients and vitamins as it did before.

This is the most common weight-loss surgery. Patients typically tolerate it well, often losing up to 70 percent of excess body weight. Gastric sleeve also reduces your body’s production of the appetite-stimulation hormone ghrelin, so you may eat less.

During this minimally invasive (laparoscopic) procedure:

  1. We remove about 75 percent of your stomach, including the fundus, which contains most of the glands in your stomach that secrete ghrelin.
  2. A narrow tube (or sleeve) of stomach remains.
