Vertical Sleeve Gastrectomy

The vertical sleeve gastrectomy procedure generates weight loss by restricting the amount of food (and therefore calories) that can be eaten by removing 85% or more of the stomach, without bypassing the intestines or causing any gastrointestinal malabsorption. It is a purely restrictive operation.

Facts about vertical sleeve gastrectomy

  • The portion of the stomach that produces the hormone that stimulates hunger (Ghrelin) is removed.
  • The stomach is reduced in volume but tends to function normally.
  • No intestinal bypass and therefore little chance of nutritional deficiencies
  • Safer alternative for high body weight (>400 pound) or medically high-risk patients.
  • No foreign body or implanted devices.
  • Can be done laparoscopically in virtually all patients.
  • 99% of patients leave the hospital within one day.

The Procedure

This procedure works by several mechanisms. First, the new stomach pouch holds a considerably smaller volume than the normal stomach and helps to significantly reduce the amount of food (and thus calories) that can be consumed. The surgery also positively affects gut hormones that in turn impact a number of factors including hunger, satiety, and blood sugar control.

Short term studies show that the sleeve is as effective as the roux-en-Y gastric bypass in terms of weight loss and improvement or remission of diabetes.

There is also evidence that suggest the sleeve, similar to the gastric bypass, is effective in improving type 2 diabetes independent of the weight loss.



  • Restricts the amount of food the stomach can hold
  • Induces rapid and significant weight loss that comparative studies find similar to that of the Roux-en-Y gastric bypass. Weight loss of >50% for 3-5+ year data, and weight loss comparable to that of the bypass with maintenance of >50%
  • Requires no foreign objects (such as used with adjustable gastric band) and no bypass or re-routing of the food stream (as occurs with roux-en-y gastric bypass)
  • Involves a relatively short hospital stay of approximately 2 days
  • Causes favorable changes in gut hormones that suppress hunger, reduce appetite and improve satiety
