Info About Body Mass Index
Body mass index (BMI) reflects a person's weight status and can help screen for conditions like obesity or overweight, which in turn can lead to serious health complications, such as diabetes, high blood pressure, and fatty liver disease. This figure is calculated using height and weight. Because the calculation requires only these two factors, it is inexpensive and easy to use.
Keep in mind that the body mass index is just a screening tool; it is not used to diagnose any medical conditions, but instead is simply used as a measure to assess a person's weight and his or her risk for developing certain medical conditions. BMI does not measure body fat directly, but it does correspond fairly closely to direct measures of body fat in most people.
