Sleeve gastrectomy

The sleeve gastrectomy (SG), often called the "sleeve", is performed by removing approximately 80% of the stomach leaving a remnant the size and shape of a banana.

​

How does it work?

​

This procedure works through several mechanisms. First, the new reservoir has a considerably smaller volume than the normal stomach, which helps significantly reduce the amount of food (and therefore calories) that can be consumed. However, the greatest impact appears to be the effect the surgery has on gut hormones that affect a number of factors, including hunger, satiety, and blood glucose control.

​

Advantages

​

• Technically simplest procedure and requires the shortest surgical time.

• Short hospital stay (24-36 hours).

• Can be performed as a first step in patients with severe obesity, leading to subsequent procedures such as gastric bypass or SADI-S.

• Effective weight loss and improvement of obesity-related conditions.

• It does not require foreign objects or bypass or redirection of the food stream.

​

What to expect?

Sleeve gastrectomy typically results in a loss of more than 70% of excess body weight (relative to initial weight), with most of this occurring in the first six months after surgery. This substantial weight loss can lead to dramatic improvement and even complete remission of many obesity-related diseases, including type 2 diabetes.
