Adjustable Gastric Band

The Band* wraps around the upper part of the stomach, dividing the stomach into a small upper pouch that holds about 1/2 cup food and a larger lower stomach. By creating a smaller stomach pouch, the Band* limits the amount of food that can be eaten at one time, so you feel full sooner and stay full longer. It does not significantly affect normal digestion and absorption. Food passes through the digestive tract in the usual order, allowing it to be fully absorbed in the body. Gastric band patients have been shown to lose 41% of their excess at 3 years.

Sleeve Gastrectomy

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. By creating a smaller stomach pouch, a sleeve gastrectomy limits the amount of food that can be eaten at one time, so you can feel full sooner and stay full longer. Sleeve gastrectomypatients have been shown to lose an average of 66% of their excess weight.

Roux En Y Gastric Bypass

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 the small intestine, limiting the amount of food that can be eaten at one time, so you feel full sooner and stay full longer. By bypassing a portion of he small intestine, your body also absorbs fewer calories. Complete resolution or improvement of some of the obesity-related health problems, including type 2 diabetes, high lipid (fat) levels, high blood pressure, and obstructive sleep apnea are common. Gastric Bypass patients are shown to lose up to 75% of excess body weight on average.
