What is Gastric Band Surgery?

During gastric band surgery, a special band is placed around the upper part of your stomach, essentially dividing your stomach into two.
When you eat, food passes from your gullet (oesophagus) into the part of your stomach above the band. Because this upper section is smaller than the size that your whole stomach was previously, you will need to eat less than before to feel full. After eating, the food then gradually passes through to the section of your stomach below the band and is digested as normal.
