Sleeve Gastrectomy

The sleeve gastrectomy has become the most commonly selected bariatric procedure.

Type of Procedure: Restrictive

The physician removes a portion of the stomach, leaving a pouch or sleeve about the size and shape of a banana. The procedure is relatively simple, and does not involve rerouting the intestines. Because the stomach still functions normally, there are usually few dietary restrictions other than quantity of food. There is less chance of malnutrition than with some other bariatric procedures.

There is no long-term weight loss data to compare, since this procedure is so new. Initial data shows patients are losing 33 to 83 percent or more of their excess weight.


  • Fewer food restrictions
  • Less hunger 
  • Does not involve any bypass of the intestinal tract
  • Suitable form of surgery for high risk patients
  • Less invasive than gastric bypass 
  • No dumping syndrome 
  • Can be performed laparoscopically in patients who are extremely overweight 


  • Does not always produce the desired weight reduction
  • Potential for inadequate weight loss or weight regain
  • No long-term scientific studies  
  • Procedure cannot be reversed
