Gastric banding is a highly effective weight loss surgical procedure that limits how much food you can eat. Also known as lap banding, the operation helps overweight people achieve substantial and long-term weight loss.
You may be eligible for surgery if your BMI (body mass index) of over 40, or if it is over 35 and you have other medical conditions. To reduce your risk of complications you may be asked to lose weight before surgery.
An inflatable band is placed around the stomach to divide it into two parts. This creates a smaller pouch at the top, taking in less food to make you feel full. The food then passes slowly through the opening into the lower part of your stomach and continues on as normal.
The gastric band can be inflated with saline solution to reduce the size of the opening into the lower part of the stomach. This will further restrict the amount of food you can eat, making you feel fuller for longer.
The band can be inserted into the abdomen using keyhole surgery, through four or five small cuts. Adjustments to the gastric band are made by injecting fluid through a very small tube, which has a special button-like reservoir just under your skin. It can be inflated and deflated in this way, until the right level of restriction is achieved. It takes several adjustments to find the right level of restriction, the exact number being tailored to each individual patient. These will be done at hospital, and the first one is usually six weeks after gastric banding.
The procedure is reversible.

• Eating a healthy and balanced diet
• Exercising regularly. Your GP can recommend exercises.
• Lung problems
• Spleen injury
• Band slippage

• Wound infections
• Blood clots
• Some patients find that after a year or two of rapid weight loss they are left with excess skin.
