DEF

A category of obesity that is defined for adults as a body mass index greater than or equal to 40.0 kg/m² and is associated with a high risk of developing many illnesses.

CONT

According to the NIH [National Institutes of Health] guidelines, individuals are stratified into six weight classes depending solely on their BMI [body mass index]: underweight (BMI [less than] 18.5), normal weight (BMI: 18.5-24.9), overweight (BMI: 25.0-29.9), moderate obesity (BMI: 30.0-34.9), severe obesity (BMI: 35.0-40.0), and extreme obesity (BMI: 40.0+).

CONT

Morbid obesity, also referred to as clinically severe obesity or extreme obesity, is a chronic disease that afflicts approximately 9 million adult Americans. ... The morbidity and mortality risk from being overweight is proportional to its degree. Individuals with morbid obesity, therefore, have the highest risk for developing numerous illnesses that often reduce mobility and quality of life due to their excess weight. In particular, type 2 diabetes, gallbladder disease and osteoarthritis have been found to increase concurrently with higher BMI [body mass index]. Premature death, a 20-year shorter life span, has also been found in individuals with morbid obesity. All of the systems that make the body function are affected by morbid obesity.
