Definition of Morbid Obesity

Calculating BMI is an effective screening tool used to measure body fat based on height and weight. Obesity is a disorder involving excessive weight with a person’s BMI of 30 and over.

Morbid obesity means that an individual is extremely obese with a high BMI of at least 40+ or over 100 pounds overfat. Severe obesity comes with the risk of severe illness.

A severely obese individual generally has one or more health problems, or comorbidity, related to the amount of excess weight. Also, those suffering from mild, moderate, or extreme obesity have a higher chance of risk for developing metabolic disorders.

These obesity-related medical conditions can include type 2 diabetes, hypertension, high blood pressure, heart and cardiovascular disease, sleep apnea, etc. There are also physical, mental, and psychological issues associated with obesity.  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. Body Mass Index strictly measures your weight in kilograms (or pounds) and your height in in inches/centimeters using standard or metric measures.
