BMI is calculated based upon a person’s height and weight, and is generally more accurate than ideal body weight calculations. This condition is associated with the development of life-threatening complications such as hypertension, diabetes, sleep apnea, and coronary artery disease, to name a few.Numerous therapeutic approaches to this problem have been advocated, including low calorie diets, medication, behavioral modification and exercise therapy.
