Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. A high BMI can be an indicator of high body fatness and having a low BMI can be an indicator of having too low body fatness. BMI can be used as a screening tool but is not diagnostic of the body fatness or health of an individual. To calculate your BMI, see the BMI Calculator.

A trained healthcare provider should perform appropriate health assessments in order to evaluate an individual's health status and risks.
