Body mass index (BMI) is a measurement based on height
in relation to weight (kg/m2), and is closely linked to a
person's body fat. BMI is designed to give patients and
health professionals a way to measure when a person's
weight is hazardous and the potential risk of developing
health conditions based on excess weight.
