About BMI
BMI is a screening tool that may indicate whether a person is underweight, overweight, or obese. However, BMI is not a diagnostic tool. To determine if excess weight is a health risk, a healthcare provider might perform further assessments such as skinfold thickness measurements, evaluations of diet, physical activity, family history, and other appropriate health screenings.
Note: BMI may not be accurate for athletes (who may have high BMI due to muscle mass) or for the elderly (who may have low BMI due to loss of muscle mass).
