BMI Calculator for Bariatric Surgery
Body Mass Index (BMI) is a number calculated from a person's weight and height and is used as part of the Bariatric Surgery methodology.
BMI is a fairly reliable indicator of body fat for most people. BMI does not measure body fat directly, but research has shown that BMI correlates to direct measures of body fat, such as underwater weighing and dual energy x-ray absorptiometry (DXA).
1, 2 BMI can be considered an alternative for direct measures of body fat. Additionally, BMI is an inexpensive and easy-to-perform method of screening for weight categories that may lead to health problems. (CDC)
