In order to qualify for weight loss surgery you have to be considered morbidly obese. By definition this term means that you suffer from obesity and because of this you are more likely to suffer from comorbidities.

The National Institute of Health (NIH) set the standards to measure and treat obesity. There are many factors that are considered. However, in the United States, if you meet the simple guidelines below you qualify to have surgery. This does not mean that your insurance company will cover surgery!

  1. You are over the age of 18.
  2. Your body mass index is over 40, or…
  3. Your body mass index is over 35 with one or more comorbid conditions. BMI, Body Mass Index, is a measurement of your height over your weight.

Most insurance companies require what the NIH requires and often a little bit more.

  • 35 BMI or higher with one or more comorbid conditions or
