Body mass index, or BMI, is a measure of body size. It combines a person’s weight with their height. The results of a BMI measurement can give an idea about whether a person has the correct weight for their height.
BMI is used by healthcare professionals to screen for overweight and obese individuals. The BMI is used to assess a person’s health risks associated with obesity and overweight.
BMI is a screening tool that can indicate whether a person is underweight or if they have a healthy weight, excess weight, or obesity. If a person’s BMI is outside of the healthy range, their health risks may increase significantly.
