Body Mass Index, or BMI calculators, have been the basic standard by which the average patient can help determine his or her eligibility for weight loss surgery. The BMI calculator can both describe what weight category you fall into and help you track your weight with a simple easy-to-understand number.

BMI calculations are approximate values and are intended to be used only as a rough guide. BMI calculators do not take into account muscle structure and age. At Advanced Surgical Associates, we can help calculate your BMI by multiplying your weight in lbs by 703. Take that number and divide it by your height (in inches) squared:
