BMI Calculator

Find out if you are a candidate­ for weight loss surgery with our BMI calculator.

Patient selection for weight loss surgery is based on the National Institutes of Health criteria:

  • 100 pounds or more above ideal body weight or a BMI of 40 or above
  • BMI of 35 or greater with one or more obesity-related health conditions

A person with that criteria would be classified as morbidly obese and would meet the initial eligibility for weight loss surgery.

This calculator is not intended to replace the evaluation of a health care professional.
