Weight Loss Surgery

Weight loss surgery, also called bariatric surgery, is used as a last resort to treat people who are dangerously obese (carrying an abnormally excessive amount of body fat).

This type of surgery is only available on the NHS to treat people with potentially life-threatening obesity when other treatments, such as lifestyle changes, haven’t worked.

Potentially life-threatening obesity is defined as:

1. having a body mass index (BMI) of 40 or above
2. having a BMI of 35 or above and having another serious health condition that could be improved if you lose weight, such as type 2 diabetes or high blood pressure

For people who meet the above criteria, weight loss surgery has proved to be effective in significantly and quickly reducing excess body fat.

However, it is always recommended that you try to lose weight through a healthy, calorie-controlled diet and increased exercise before you consider weight loss surgery, as surgery carries a risk of complications and requires a significant change in lifestyle afterwards.

Due to these associated risks, most surgeons, whether they are working privately or in the NHS, would only consider a person for surgery if there was a clinical need, and not just for cosmetic reasons.

Availability of weight loss surgery

Even if you are eligible for weight loss surgery, the demand for this surgery on the NHS is currently higher than the supply in many areas of the country. Therefore, there may be a considerable waiting list.

Types of weight loss surgery

The 3 most common weight loss surgery abroad requested is:

Gastric Wrap is where the surgeon reduce the size of the stomach by stitching it; so a smaller amount of food is required to make you feel full

Gastric Sleeve is where the surgeon reduce the size of the stomach by stapling it; so a smaller amount of food is required to make you feel full

Gastric Bypass is where your digestive system is re-routed past most of your stomach so you digest less food and it takes much less food to make you feel full

We also offer revisional or 2nd stage gastric procedures such as re-sleeving or conversion to gastric bypass from gastric warp, gastric sleeve or gastric band.

SectionLife after weight loss surgery

Weight loss surgery can achieve often impressive results in the amount of weight lost, but it should not be seen as a magic cure for obesity.

People who have had weight loss surgery will need to stick to a rigorous and lifelong plan afterwards to avoid putting weight back on or long-term complications.

This plan will include

A carefully controlled diet, regular exercise, the rapid weight loss may cause relationship problems, for example with a partner who is also obese, and it may lead to unwanted loose folds of skin, which may need further surgery to correct.

Also, many people with mental health problems, such as depression or anxiety, find that these problems do not automatically improve because they have lost weight.

It is important to have realistic expectations about what life after weight loss surgery will be like.


As with all types of surgery, weight loss surgery carries the risk of complications, some of which are serious and potentially fatal, such as:

internal bleeding
a blood clot inside the leg (deep vein thrombosis)
a blood clot or other blockage inside the lungs (pulmonary embolism)
It is estimated that the risk of dying shortly after gastric band surgery is around 1 in 2,000. A gastric bypass carries a higher risk of around 1 in 100.
However, this risk can be as high as 1 in 40 if you have other risk factors such as high blood pressure or a BMI of 50 or above.


As long as a person is willing and able to stick to their agreed plan afterwards, surgery can effectively reduce their weight and treat conditions associated with obesity, such as diabetes.

Recent research carried out in America found that on average:

People with a gastric wrap will lose around half their excess body weight.
People with a gastric sleeve and gastric bypass will lose around two-thirds of their excess body weight.
These techniques also lead to a considerable improvement (and sometimes a complete cure) of obesity-related conditions, such as diabetes or high blood pressure.
