A free self-check

Know your numbers

Two minutes, ten questions or fewer, no email. See which routine checks guidelines suggest for adults like you, and where your BMI and waist sit against the limits used for South Asian adults. Everything stays on this page: nothing you type is sent or saved.

Sex

Optional, but they make the answer more useful. Not sure how to measure your waist? Here is the method.

Has a parent, brother or sister had a heart attack or stroke early: a man before 55, or a woman before 65?
Has a parent, brother or sister had type 2 diabetes?
Do you smoke?
Have you been told you have high blood pressure, diabetes or pre-diabetes, high cholesterol, heart disease or kidney disease?

Nothing you type is sent or saved.

How this check works

It applies published screening guidance to your answers. It does not diagnose anything, and it cannot replace a consultation, an examination or laboratory investigations. It is an estimate, not a medical assessment.

Where guidelines differ, it uses the numbers our reports use, and says whose guidance each one is. For the weight-related questions it uses the lower limits used for Asian and South Asian adults: a BMI of 23 and a waist of 90 cm for men or 80 cm for women. Why those numbers matter is explained in A healthy waist size for a South Asian body.
