NURSE IF NEEDED:
A gastric band is a band that can be surgically fitted to the top of your stomach to make you feel full after eating a small amount of food, which will help with weight loss.
A gastric bypass involves re-routing your digestive system past most of your stomach, so you digest less food so it takes less to make you feel full.
A gastric balloon is a non-surgical procedure where a small balloon is inserted into the stomach through the mouth.
The balloon is then filled with a sterile saline solution to reduce the available capacity of the stomach for food.
