Another option is the Vertical Sleeve Gastrectomy. Over the past few years it has gained popularity as a choice with individuals seeking Bariatric surgery, especially since the digestive tract anatomy is not altered, only the stomach itself. Typical weight loss with the sleeve is fifty percent of excess body weight within one to two years post surgery.

With the VSG, the stomach is divided vertically and eighty five percent of it is removed. This part of the procedure is not reversible.

The nerves to the stomach and the outlet valve (pylorus) remain intact to preserve normal stomach function. The major change is reducing the stomach’s volume. There is no intestinal bypass with this procedure, only stomach reduction. The procedure is appropriate for both low and very high BMI patients.

Vertical sleeve gastrectomy is not a quick fix for obesity. It will greatly change your lifestyle. You must eat healthy foods, control portion sizes of what you eat, and exercise after this surgery. If you do not follow these measures, you may have complications from the surgery and poor weight loss.

This procedure may be recommended if you have:

A body mass index (BMI) of 40 or more. Someone with a BMI of 40 or more is at least 100 pounds over their recommended weight. A normal BMI is between 18.5 and 25.
A BMI of 35 or more and a serious medical condition that might improve with weight loss. Some of these conditions are sleep apnea, type 2 diabetes, and heart disease.
Vertical sleeve gastrectomy has most often been done on patients who are too heavy to safely have other types of weight-loss surgery. Some patients may eventually need a second weight-loss surgery.

This procedure cannot be reversed once it has been done.


Vertical sleeve gastrectomy is surgery to help with weight loss. The surgeon removes a large portion of your stomach.
