The Adjustable Gastric Band System Gastric Bypass Roux-en-Y reduces the capacity of the stomach by creating a small stomach pouch. The small space holds only one ounce of fluid. The procedure also constructs a tiny stomach outlet, which slows the speed by which food leaves your stomach. So you will feel full after eating a small amount and you will stay satisfied for a long time.

The Adjustable Gastric Band System
The band is a simple silicone ring with an inflatable balloon fitted on the inside. The balloon is connected to an injection port by a long, thin, kink resistant silicone tubing. Like a wrist- watch, the band is fastened around the upper stomach, about 15mm below the gastro-esophageal junction. This divides the stomach into a small upper pouch (15ml) and the remainder lower stomach.
