BMI is a screening tool, not a diagnosis — it doesn't account for muscle mass, bone density, or where you carry fat, and NHS guidance uses different thresholds for some ethnic groups. If you're outside the healthy range or concerned about your weight, talk to a pharmacist or GP — many pharmacies offer a [weight management service](/services/weight-management/) with a proper clinical assessment.
