Obesity Center


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 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:

  • having a body mass index (BMI) of 40 or above
  • 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. 


The medical society is currently considering lowering the threshold for weight loss surgery to a BMI of over 30 for people who have recently been diagnosed with type 2 diabetes.


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,  would only consider a person for surgery if there was a clinical need, and not just for cosmetic reasons.

Types of weight loss surgery

The three most widely used types of weight loss surgery are: 

  • gastric band, where a band is used to reduce the size of the stomach so a smaller amount of food is required to make you feel full
  • gastric bypass, 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
  • gastric sleeve surgery that includes removing part of the stomach and reducing its volume





Life 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:


A 2014 American review of over 157,000 patients found the overall risk of death, within 30 days of having any kind of weight loss surgery, is around 1 in 1000. The risk of death after having a gastric bypass was slightly higher.


However, certain risk factors, such as high blood pressure or a BMI of 50 or above, increase the risk of complications.


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 band will lose around half their excess body weight
  • people with a gastric bypass or sleeve gastrectomy will lose around two-thirds of their excess body weight


All  techniques also lead to a considerable improvement (and sometimes a complete cure) of obesity-related conditions, such as diabetes or high blood pressure.


Body mass index and obesity

The most widely used method of seeing if you are a healthy weight is to calculate your body mass index (BMI). This is your weight in kilograms divided by your height in metres squared:

  • If your BMI is 25-29.9, you are over the ideal weight for your height (overweight).
  • If your BMI is 30-39.9, you are obese.
  • If your BMI is over 40, you are very obese (known as morbidly obese).


BMI does not provide an accurate assessment of weight in all circumstances, such as in people who are very muscular or children going through a sudden growth spurt.
