Meet The Surgeon

How heavy do I have to be to have weight loss surgery?

There is no minimum ‘weight’ to be eligible for bariatric surgery because we use a special formula called the Body Mass Index (BMI). BMI takes into account your height as well as your weight – the upper end of the normal range for your BMI is around 25.

In order to qualify for bariatric surgery, you may need a BMI of 40 or above. However, the lower BMI limit for surgery can vary as it depends up on your medical circumstances and ethnicity. For some it can be as low as 27.5. We can talk you through whether or not you are a suitable candidate following a detailed medical consultation.
