Sleeve Gastrectomy

Minimally Invasive    |    Laparoscopic    |     Robotic




Sleeve gastrectomy involves removal of ~80% of the stomach which results in ~70% excess body weight loss over the course of one year

How is the gastric sleeve performed?

A special device called a bougie is used to size the stomach. The size of the stomach is reduced to approximately the size of a banana. The remainder of the stomach is removed.

Does bariatric surgery result in long term weight loss?

The majority of patients who undergo weight loss surgery maintain their weight loss long term as opposed to those who lose weight with traditional diet and exercise alone. 

Minimally invasive

Small incisions are used to create a keyhole in the body through which instruments are passed to complete the operation. Resulting in faster recovery and minimal pain.

How much weight can be lost after sleeve gastrectomy?

Patients lose approximately 70% of their excess body weight. 

Expected Weight loss

How does the sleeve surgery result in weight loss?

The vertical sleeve gastrectomy (VSG) is a restrictive operation. The size of the stomach is reduced which results in restriction on the amount of food one can eat. Although it is a restrictive operation there are also hormonal effects as well thus making the sleeve gastrectomy a metabolic operation as well. 

Blood levels of the hormone Ghrelin are reduced after bariatric surgery. Ghrelin is the “hunger hormone” and is the hormone responsive for the drive to eat. Decreasing this hormone decreases the hunger drive.


How do you qualify for the sleeve gastrectomy?

Mainly depends on body mass index (BMI)

BMI> 40 without a medical condition or >35 with an obesity related medical condition will qualify you for surgery

Beyond this it is mainly dependent on your insurance which usually requires a supervised diet program and evaluation by a psychologist.
