Note: BMI is a screening tool, not a diagnostic measure. It does not account for muscle mass, bone density, age, sex, or fat distribution. A high BMI may indicate increased risk of certain health conditions, but consult a healthcare provider for a full assessment. BMI ranges for children and teens differ from those for adults.
