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.
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
