What is morbid obesity?

Overweight and obesity are both labels for ranges of weight that are greater than is generally considered healthy for a given height. Morbid obesity refers to individuals who are 50 - 100% above their ideal body weight. It is most frequently measured by body mass index (BMI). The BMI is a measure of your weight relative to your height and an adult individual who has a BMI of 30 - 40 is considered obese and over 40 as morbidly obese. Once a person reaches the level of morbid obesity, the weight causes quicker and more extensive damage to the body.
