Find out how sleeve gastrectomy could potentially help you lose weight



The sleeve gastrectomy procedure can be the first step before other surgical procedures (e.g., gastric bypass) or it may be employed as a single procedure for weight loss.

  • The surgeon creates a small stomach "sleeve” using a stapling device; the rest of the stomach is removed.
  • This procedure induces weight loss in part by restricting the amount of food (and therefore calories) that can be eaten without bypassing the intestines and therefore absorbed.
  • Weight loss and improvement in parameters of metabolic syndrome are connected with the resection of the stomach and subsequent neurohormonal changes.
  • If the sleeve gastrectomy is used as the first step before gastric bypass, in the second step the surgeon attaches a section of the small intestine directly to the stomach pouch, which allows food to bypass a portion of the small intestine.

Sleeve gastrectomy procedure

The majority of weight loss sleeve gastrectomies performed today use a minimally invasive laparoscopic technique. The entire procedure is done through a small incision in your abdomen. Most surgeons prefer this method because it results in shorter hospital stays, faster recoveries, smaller scars, and less pain than open surgical procedures.
