Morbid obesity is a term used to describe a severe form of obesity that is characterized by having a body mass index (BMI) of 40 or higher OR a BMI above 35 with other medical conditions as a result of the obesity.
Obesity can eventually lead to other serious health complications such as heart disease, diabetes, high blood pressure, and sleep apnea.
While BMI can be a useful tool, it has limitations. It does not take into account the person’s body composition or distribution of body fat. For example, someone who is a body builder has a high muscle mass may have a higher BMI, but they may not necessarily be obese or at risk for related health conditions.
