Obesity is a life-long, progressive, life-threatening condition marked by excess body fat, which can significantly reduce life expectancy. When weight increases to an extreme level, it is called morbid obesity, and is a chronic condition with numerous medical, psychological, social and economic consequences. Morbid obesity is diagnosed when a person has a body mass index (BMI)* greater than 40, or greater than 35 with weight-related health problems. Health problems associated with morbid obesity include diabetes, high blood pressure, high cholesterol, heart disease, sleep apnea, arthritis, depression, stress incontinence, menstrual irregularity,infertility and some types of cancer. Weight loss can greatly reduce these risks, improve overall health, and enhance quality of life.
*BMI is defined as a person’s weight in kilograms (kg) divided by their height in meters (m) squared. That is, BMI = weight in kg/(height in m)2
