Why weight loss surgery is done

Reasons for weight loss surgery

Weight loss surgery may be available on the NHS if:

  • you have a body mass index (BMI) of 40 or more
  • you have a BMI between 35 and 40 and a condition that might improve if you lost weight – these include high blood pressure, diabetes, arthritis, breathing problems and asthma
  • you agree to make healthy lifestyle changes and attend regular check-ups after surgery

Availability of weight loss surgery varies across areas of the UK. You can also pay for surgery privately, but this can be expensive.
