Weight loss surgery

Choosing to have weight loss surgery, also known as bariatric surgery, isn't an easy or straightforward decision. Weight loss surgery is usually only considered if you are, unable to achieve healthy weight loss through exercise and diet.

The National Institute for Clinical Excellence (NICE) states that to be eligible for surgery, you must have a body mass index (BMI) of 40 and above, or between 35 and 40. You must also have been diagnosed with a condition that could improve through weight loss. We are proud to facilitate specialist bariatricians who can help support you throughout your weight loss journey. Our bariatric specialists will perform an in-depth assessment to determine if bariatric surgery is the best option for you and recommend possible treatments.

The most common reasons why you might need to have weight loss surgery include:  

High blood pressure: High blood pressure can put pressure on your blood vessels, heart and brain. If left untreated, it can place you at high risk of having a heart attack and stroke. A gastric bypass can help regulate blood pressure levels.  

Type 2 diabetes: This occurs when your blood sugar levels become too high. The American Diabetes Association reveals a gastric balloon surgery can be effective for managing type 2 diabetes and improving your quality of life. 

Obesity: Being obese (extremely overweight) can place you at risk of developing type 2 diabetes, coronary heart disease and breast cancer. If you are obese, you may be advised to have a gastric band surgery.  

A body mass index (BMI) of 50 and above
: If your BMI is 50 and above, you could be considered for weight loss surgery, such as gastric sleeve surgery, without having to try alternative weight loss methods first.

Treatment for weight loss with BMI Healthcare will be carried out by our multidisciplinary team, comprising of dedicated bariatric Consultants, gastroenterologists, dietitians and more.  

Our specialist Consultants at BMI Healthcare hospitals will discuss your symptoms and carry out an assessment to confirm if you meet the NICE guidelines for weight loss surgery. This assessment will look at your diet, medical history, and measure your body mass index (BMI). Your Consultant will also answer any questions that you may have.

Gastric band surgery

A gastric band is a band that is placed around the outside of your stomach. A gastric band creates a small pouch-like area at the top of your stomach. Less food is needed to fill this pouch and after surgery, you’ll find you don’t need to eat as much food as usual to feel full. Your gastric band is connected to a small device, which is usually inserted near the centre of your chest. This device allows the band to be tightened post-surgery.  

Gastric bypass surgery

Your surgeon will use surgical staples to form a small pouch at the top of your stomach. This pouch will be connected to your small intestine and bypass the rest of your stomach. It allows you to feel full after eating less food than you usually would.  

Gastric sleeve surgery

A gastric sleeve surgery or a sleeve gastrectomy involves making your stomach smaller by removing a large section of your stomach. This limits your food intake and allows you to feel full more easily.  

Gastric balloon surgery

A small, silicon balloon is placed into your stomach and filled a with sterile saline (salt water) solution. The balloon allows you to feel full sooner. But it’s a temporary weight loss solution and the balloon will need to be removed after six months.
