Am I eligible for weight loss surgery


Eligibility criteria for weight loss surgeries is based on your BMI, whether you have a serious health condition that could be improved if you lost weight and if you’ve tried all the appropriate non-surgical methods,such as diet and exercise, but failed to achieve or maintain a beneficial level of weight loss.

You'll need to be fit and healthy enough to withstand anaesthesia and the weight loss surgery.Also you’ll need to agree to commit to long term follow up treatment after surgery and to a new healthy diet and lifestyle.

How to calculate BMI

The formula to calculate BMI is: BMI = Weight (kg)/Height (m)².

For simplicity you can use our BMI calculator to find out your BMI.

NICE eligibility criteria for weight loss surgeries

There are eligibility guidelines for weight loss surgery produced by NICE. In summary NICE advises that a person should be considered for bariatric surgery if:

a) they have a BMI of over 40 and have tried to lose weight by attending a weight management programme and have also tried, where appropriate, the available prescription anti-obesity drugs and been monitored by their family doctor.

b) they have a BMI of over 50. In this case weight loss surgery can be considered without the patient having necessarily tried different approaches to lose their excess weight.

c) if the person has a BMI of 35 to 40 but has one of the serious co-morbidities: type 2 diabetes, hypertension, sleep apnoea, and otherweight loss options have failed.
