Take the First Step

Answering this question may give you the courage you need to take the first step. Here are tools you can use to determine if you are morbidly obese and potentially a candidate for weight loss surgery. There are several medically accepted criteria for defining morbid obesity. You are likely morbidly obese if you are:

  • more than 100 lbs. over your ideal body weight,
  • have a Body Mass Index (BMI) of over 40, or have a BMI of over 35 and are experiencing severe negative health effects, such as high blood pressure or diabetes, related to being severely overweight,
  • unable to achieve a healthy body weight for a sustained period of time, even through medically supervised dieting.

Select your height and weight to calculate your BMI. The results of the BMI calculations are displayed below. Note that these are approximate values, and are intended to be used only as a rough guide.
