Procedure description

REALIZE Adjustable Gastric Band

Gastric bypass

Sleeve gastrectomy

The REALIZE Adjustable Gastric Band wraps around the upper part of the stomach, dividing the stomach into a small upper pouch that holds about 1/2 cup of food and a larger lower stomach.

The degree of band tightness affects how much food you can eat and the length of time it takes for food to leave the stomach pouch.More about Gastric Banding >

In this procedure, the surgeon creates a small stomach pouch and attaches a section of the small intestine directly to the pouch. This allows food to bypass a portion of the small intestine. More about Gastric Bypass >

During the sleeve gastrectomy procedure a thin vertical sleeve of stomach is created using a stapling device. The sleeve is about the size of a banana. The rest of the stomach is removed. More about Sleeve Gastrectomy >

Weight loss surgery can be performed using open surgery or laparascopic surgery. Laparoscopic surgery is considered to be minimally invasive because it's performed through small incisions. A laparoscopic procedure usually results in a shorter hospital stay, faster recovery, smaller scars, and less pain than open surgical procedures. Most surgeons prefer the laparoscopic approach.
