Bariatric Surgery

Bariatric surgery is an option to consider if your weight is interfering with your quality of life or causing you medical harm, and you are ready to permanently change your diet, approach to physical activity, and lifestyle.

Kaiser Permanente Hawaii performs 3 types of bariatric surgery

Roux-en-Y gastric bypass

Roux-en-Y (pronounced "roo-en-why") surgery disconnects part of the stomach to create a new, smaller stomach.

Vertical Sleeve Gastrectomy (VSG)

The surgery is usually done through several small incisions in the belly. The doctor removes more than half of the stomach, leaving a thin sleeve about the size of a banana.

Laparoscopic adjustable gastric banding

In this surgery, the doctor wraps a band around the upper part of the stomach to create a small pouch.
