Interpreting Your BMI


BMI Weight Category
Under 18.5 Underweight
18.5- 24.9 Normal
25 - 29.9 Overweight
30 - 34.9 Obese
35 - 39.9 Clinically Obese
40 or greater Morbidly Obese

Body Mass Index (BMI) is a general indicator of whether or not you are maintaining a healthy weight based on the ratio of your weight to your height. It’s an imperfect scale as it doesnt account for differences in body types. For example, a 5 foot 9 inch bodybuilder who weighs 215 pounds and has a 6% body fat would be labeled obese. And there is already a new scale just for people from Southeast Asia where the ranges are lowered.

While it can be a good indicator of the healthiness of your weight if you fall within certain statistical norms that were used to develop it, it should be taken with a significant grain of salt and should not be used as a substitute for a professional evaluation of your health by a doctor.

Discover Surgical Weight Loss Options

By looking into a weight management program you are already on your way to making a positive change in your health. The Center for Weight Management & Bariatric Surgery has many options to help meet your goals and support you along the way.

Are You a Candidate for Surgical Treatment?

The National Institutes of Health set minimum requirements for recommending bariatric surgery as a treatment option:

  • 100 pounds or more above ideal body weight or a BMI of 40 or greater
  • BMI of 35 or greater with one or more obesity-related health condition
  • Your individual health history and other medical conditions

Not everyone who is overweight or obese is a candidate for bariatric surgery, but it may be right for some. In order to be considered as a candidate for Gastric Bypass Surgery, patients must:

  • have made multiple attempts to lose weight, including structured programs through nationally recognized organizations or physician supervised programs
  • weigh at least 100 pounds over their ideal body weight with a Body Mass Index of >35 with co-morbidities or >40 with no current co-morbidities
  • be motivated to undergo a change in lifestyle and eating habits
  • be willing to work collaboratively with a team of healthcare providers interested in their successful journey to a healthier lifestyle
  • be between 18-60 years old

Learn about the types of bariatric surgery.
