How the calculator works

Confirm

Check that you are 18 or older and not pregnant.

Measure

Enter height and weight in the units you know.

Understand

See your BMI and screening category to one decimal place.

What BMI can and cannot tell you

BMI compares weight with height. It can help screen for weight-related health risk, but it does not account for every factor affecting health.

A result is not a diagnosis and cannot decide treatment eligibility. A pharmacist can discuss it alongside your health, medicines and circumstances.
