Medically supervised weight loss programs give patients the tools they need to lose weight and keep it off. The main purpose is not only to help patients lose and manage their body weight, but also to maintain a healthier lifestyle, improve quality of life and decrease the risk of diseases such as coronary heart disease, high blood pressure, stroke, type 2 diabetes, abnormal blood fats, metabolic syndrome, cancer, osteoarthritis, sleep apnea, obesity hypoventilation syndrome, reproductive problems or gallstones.
