Bariatric and Metabolic Surgery

Gastric Banding or Gastric Band Surgery

The gastric band is a type of weight loss surgery (bariatric operation) for people who are morbidly obese. Band operation involves putting a silicone, adjustable ring around the stomach, just below the esophagogastric junction. This band restricts the food passage and your stomach will hold less food. This means, you feel full with less food and quickly. Because of the reduced calorie intake, you’ll start losing weight.

Like other bariatric operations, gastric band may be suitable if you are struggling with obesity more than 2 years and you haven’t been able to lose weight just by diet, changing lifestyle and even weight loss medicines. Current studies show that patients usually lose around 50 % of their excess weight in the first two to three years after gastric band surgery. But it’s just an adjunct method, you also need to follow a healthy diet and exercise regularly after the operation.

If your GP thinks weight loss surgery would help you, you may be eligible for gastric band operation.

You can check the eligibility criteria for weight loss surgery below:

Having a BMI more than 40, or having a BMI over 35 and a serious health condition developing by obesity, such as Type 2 diabetes, high blood pressure, blood lipid abnormalities.

Being fit for general anaesthesia and laparoscopic surgery.
