causes of morbid obesity in Adults

Morbid obesity is defined as body mass index (BMI) greater than 40. Since obesity is a disease of excessive body fat - which itself is caused by taking in more calories than are burned - the causes of morbid obesity must include those factors which raise calorie-intake and depress calorie expenditure. Thus eating habits, calorie content of popular foods, and metabolic disorders relating to digestion or food metabolism, are all likely to be contributory risk factors, as well as physical conditions which prevent regular exercise. Other important causes of obesity include genetic factors, disease, use of medications, as well as cultural, socioeconomic and psychosocial factors.
