Gastric Sleeve (Vertical Sleeve Gastrectomy)

The Gastric Sleeve, which is also called Vertical Sleeve Gastrectomy - or Sleeve for short - is a restrictive bariatric surgery. It generates weight loss by restricting the amount of food that can be eaten without any bypass of the intestines or malabsorption. The stomach is cut vertically and more than 85 percent is removed. The remaining stomach is shaped like a thin banana and measures from 2-5 ounces. Therefore, the stomach left is physically much smaller. In addition, the part of the stomach that is removed is where some hunger hormones are made. This results in a decrease in appetite.

Previously performed for only those who are high risk or super-super-obese - today the gastric sleeve is being performed on patients who are interested in avoiding a foreign body and/or do not want to maintain follow-up care through routine adjustments of a gastric band. Our surgeons can help you understand the benefits, process, and risks associated with the gastric sleeve surgery.

Vertical Sleeve Gastrectomy


  • Weight loss is typically rapid, averaging about 65% of excess weight loss in the first 1-2 years after surgery

  • No implantation or maintenance of a foreign body

  • Fewer postoperative visits (as compared to a Lapband)

  • No malabsorption. Chance of nutritional deficiencies are very low

  • Eliminates the portion of the stomach that produces the hormones that stimulates hunger (ghrelin)


  • Non-reversible

  • Potential leaks and other complications related to stapling may occur such as bleeding and stricture. A leak happens when the sealed staple line of the new stomach bursts and causes internal infection. This can be very serious requiring extensive medical treatment and hospitalization. Statistics show that it happens approximately 1% of the time.

  • The new stomach may stretch in the long-term which can lead to weight regain. Because this operation has become more popular recently, there is little long-term data on weight maintenance

  • Just like any bariatric operation, it is a tool to help you lose weight. Nothing is fool-proof.

Ultimately, there are various appropriate treatment modalities for each patient, and surgeons must use their judgment in selecting from among the different feasible treatment options.
