Definition of Morbid Obesity
Morbid obesity means that an individual is extremely overweight with a high BMI of at least 40+ OR over 100 pounds overweight. Body Mass Index (BMI) is a scale measuring an individual’s excess weight based on factors of height and weight.
A morbidly obese individual generally has one or more health problems, or comorbidity, related to the amount of excess weight. Also, those suffering from being obese have a higher chance of risk for comorbidities and health issues. These obesity-related medical conditions can include type 2 diabetes, hypertension, high blood pressure, sleep apnea, etc.
Morbid obesity typically defines a body mass index level that is suitable to qualify for weight loss surgery in the United States.

Body Mass Index is a widely used tool to measure obesity. BMI is a very “general” measurement of obesity using height and weight as the only factors.
With only two factors measuring excess body fat, BMI does not take into account things like muscle, % body fat, and individuals who have certain variables that put them in a different obesity class than they should be.
What BMI is Considered Morbidly Obese?
According to the National Heart, Lung, and Blood Institute, BMI measures an individuals body fat strictly by both height and weight as a standard metric.
- BMI = 18.5 to 24.9 – Normal
- BMI = 25 to 29.9 – Overweight
- BMI = 30 to 39.9 – Obese
- BMI = 40+ – Morbidly Obese
