Are you eligible for a procedure?

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.

The 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.
