About Gastric Sleeve Surgery

Gastric sleeve surgery (also known as sleeve gastrectomy) involves removing a large portion of the stomach to decrease the volume from approximately 30-40 ounces to 3-4 ounces. Over time the small stomach will expand to approximately 6-8 ounces. The gastric sleeve operation is done laparoscopically, generally through 5 small incisions.

Hospital stay after surgery is usually 1-2 days. Recovery is generally rapid because of the minimally invasive laparoscopic approach. Patients typically return to work in 1-3 weeks.

Gastric Sleeve Weight Loss

Published studies from the better surgeons report that patients average 60-80% EWL (excess weight loss) after sleeve gastrectomy surgery. Long-term studies (5-8 years) show that the average patient maintains the majority of his/her weight loss over time.*

Choice of surgeon impacts outcomes

Sleeve gastrectomy causes weight loss by restricting food intake and by altering the biology of weight regulation by resetting the body weight “set-point” to a lower weight.*

Altering the biology of weight regulation is the key to why gastric sleeve surgery works as well as it does. A lowered body weight set-point is what makes long-term maintenance of weight loss possible after surgery. Because nonsurgical weight loss methods don’t change the body weight set-point, long-term maintenance of weight loss after diet and exercise programs is virtually impossible.*

Why Gastric Sleeve Surgery?

The gastric sleeve operation has become the most popular operation for weight loss in the United States and throughout the world over the past 10 years (more here). Reasons include:

Excellent Weight Loss
Weight loss after sleeve gastrectomy, according to the published studies from the better surgeons, is typically excellent, averaging 60-80% EWL (excess weight loss). Weight loss is typically fast and dramatic, occurring over about one year. Long-term (5-8 years), studies show that patients tend to maintain the majority of their initial weight loss.*

More Normal Anatomy
GI tract (stomach, intestines) anatomy is preserved in a more normal form with sleeve gastrectomy. There is no intestinal rerouting like with gastric bypass, and no implanted foreign body like with LAP-BAND®. This more normal anatomy results in a lower risk for long-term issues.*

More Normal Stomach Function
The gastric sleeve stomach functions much like a normal stomach, but with a much decreased volume. This preserves a more normal experience of eating compared to the gastric bypass and LAP-BAND®.*

Gastric Sleeve Orange County – Am I a Candidate?

Gastric sleeve Orange County candidates generally must be at least 50-100 pounds overweight (BMI 30 or greater), and have tried and failed to lose weight and keep it off.

Insurance companies are more restrictive – candidates generally must have either a BMI of >40, or a BMI of 35-40 with other medical problems such as diabetes, high blood pressure, or sleep apnea. Insurance companies often also have other onerous requirements, such as the completion of a 6-month medically supervised weight loss program prior to surgery.
Payment options

Good gastric sleeve Orange County candidates also understand that surgery is a tool to help with weight loss, not a cure for obesity. Good candidates understand the necessary changes they need to make in their eating/exercise habits after surgery, and are willing/capable of making these changes.

What Are the Risks?

Sleeve gastrectomy is considered a safe operation, but complications can occur, as they can for any operation.

Early Complications
The two most feared potential early complications after gastric sleeve surgery are bloods clots and leaks. The risk for blood clots and leaks can be minimized with quality surgery and good patient care, but not completely eliminated.*
More about leaks

Late Complications
A major strength of sleeve gastrectomy over gastric bypass and LAP-BAND®, as explained above, is the lower risk for long-term complications. The primary potential long-term complication is heartburn/gerd. The risk for heartburn/gerd can be minimized with quality surgery (choice of surgeon important), but not completely eliminated.*
