What is my BMI?

Calculate your BMI

Body mass index (BMI) is the measure most often used by medical professionals to determine if you have a healthy body weight. The higher your BMI, the more your health is at risk.

A BMI calculator simply divides your weight in kg by your height in metres squared. There will be other considerations which determine your eligibility, however, if you want a simple understanding of which procedures you are eligible for the BMI calculator is a great place to start.

For most adults, an ideal BMI is in the 18.5 to 24.9 range.

If you have a BMI of 27 you may be eligible for one of our weight loss options, and if it is 30 you may be eligible for a surgical procedure such as the gastric sleeve.

You are a healthy BMI and therefore ineligible for any of the weight loss procedures we offer.

Your weight is just above the healthy range. Diet and exercise is likely to be the best way to lose the weight you want to.

The gastric balloon is the only procedure available with a BMI between 27-30.

The non-surgical sleeve (ESG) has recently been made available at this BMI. The adjustable gastric band is the only other surgical option. The gastric balloon is a non-surgical alternative, but less effective than surgery.

The sleeve, ESG and band are both great options at your BMI. Ask our team to explain the differenecs and pros and cons of each.

You are eligible for all of the surgical procedures as well as the ESG. Sleeve is an increasingly popular choice at this BMI. We'll explore all 4 options before you decide what's best for you.

At this BMI the bypass and sleeve are the procedures we would consider first. How your weight affects your health will be an important consideration.

*Disclaimer: The procedures highlighted for your consideration in this BMI checker are for guidance only based on BMI alone. They are not a recommendation. The procedure that is best for you will be a decision you will make following a face to face consultation with the surgeon at which your general health, weight loss objectives and other factors will also be a considered.
