A gastric band is designed to help reduce portion size and keep you feeling fuller for longer. It works by reducing the capacity of the stomach and stimulating the nerves that are involved in the hunger process. It can be done as a keyhole procedure and also as a day case.
- You have a Body Mass Index (BMI) of between 30-40 and suffer from a weight related condition (including diabetes, heart disease or high blood pressure)
- You are morbidly obese (have a BMI of over 40)
- You have tried to lose weight in the conventional way, through diet and exercise, but have failed to lose a significant amount of weight.
- You are fit to undergo a general anaesthetic
Gastric band surgery is almost always carried out using keyhole surgery as it causes less pain afterwards and you’ll recover more quickly than following traditional surgery.
During keyhole surgery, a series of small incisions will be made in the abdomen, rather than one large incision. A laparoscope (a thin, rigid tube containing a light and a camera) will then be inserted through one of the cuts. The camera relays images of the inside of your abdomen to a television monitor. The surgeon will place an adjustable band around your stomach to create two compartments, keeping a narrow opening between the top and bottom of your stomach so that food can pass through it slowly.
The operation typically takes around one hour.
