When it comes to determining if you are a candidate for bariatric surgery, the most important factor to consider is your BMI (Body Mass Index). Patients with a BMI over 35, who have been unable to effectively lose weight through diet and exercise programs, can potentially be candidates for bariatric surgery.

BMI, which assesses body weight, is calculated by dividing an individual’s weight (in pounds) by his/her height (in inches squared) and multiplied by 703. Although BMI is considered the most effective tool for determining body fat and obesity, it does not directly measure body fat or muscle density. Use our BMI Calculator to see your results.

How does your BMI measure up?
Below 18.5 = Underweight
18.5 – 24.9 = Normal
25 – 29.9 = Overweight
BMI of 30+ = Obese

*It is important to consult your physician if your BMI falls outside of the normal range.


In addition to your BMI, several other important factors are considered when determining your candidacy for a bariatric procedure. These factors include:

  • Family history of
    chronic diseases

  • Pre-existing medical conditions

  • Abdominal fat/waist circumference
