Adjustable Gastric Band (AGB)
The Adjustable Gastric Band is a device made of silicone that is placed around the top part of the stomach to limit the amount of food a person can eat. It has been available in the United States since 2001. The impact on obesity-related Diseases and long-term weight loss is less than with other procedures. its use has therefore declined over the past decade.
This device is placed and secured around the top part of the stomach creating a small pouch above the band.
How It Works
The feeling of fullness depends upon the size of the opening between the pouch and the rest of the stomach. The opening size can be adjusted with fluid injections through a port underneath the skin. Food goes through the stomach normally but is limited by the smaller opening of the band. It is less successful against type 2 diabetes and has modest effects on the metabolism. Advantages
