A physician-supervised medical weight loss program may be the safest and wisest way to lose weight and maintain the loss. Overweight and obesity are frequently accompanied by other medical conditions such as type 2 diabetes, hypertension, cancer and others. A bariatric physician is trained to detect and treat these conditions, which might go undetected and untreated in a non-medical weight loss program. In many cases, the drugs needed to treat these conditions will no longer be needed with successful weight loss.
