What to include
If you are reporting a factual correction, please include a link to the source you believe is more accurate (for example, an NHS or NICE page). If you are asking about the calculator, it helps to include the height, weight, age and sex you entered so we can reproduce the result.
What we cannot help with
We cannot offer medical advice, interpret your individual BMI result, or recommend a weight-loss plan. For those questions please speak to your GP or use the NHS healthcare routes linked from our guides.
