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.
