BMI is a screening estimate, not a diagnosis and not medical advice. It does not measure body fat directly. For health questions, talk to a doctor or nurse. Categories are population guidelines from the WHO and CDC and do not account for individual factors. Under-20 results are shown without a category on purpose.
