The Gastric Band procedure helps you lose weight by physically changing the size of your stomach. When your stomach is smaller, it reduces the amount of food you can eat at one time. Gastric banding may also help you feel fuller sooner and for longer than usual. As you eat less food, your body will stop storing the excess calories and start using its fat supply for energy.
Gastric banding has been shown to resolve or improve:
Type 2 diabetes
High blood pressure
