Morbid obesity is defined as having a Body Mass Index (BMI) of over 40. BMI is calculated as weight in kilograms divided by the square of height in meters. BMI is a screening tool, but it does not diagnose body fatness or health. A trained health care provider should perform appropriate assessments to evaluate an individual’s health status and risks.
It is important to note that BMI is not always accurate, so healthcare providers may use other tests and tools to assess obesity, such as measuring waist circumference. Class III obesity is another term used to describe morbid obesity, which is defined as having a BMI of 40 or higher or a BMI of 35 or higher and experiencing obesity-related health conditions.
