bariatric

Baros means "weight" in Greek; so, for example, a barometer is an instrument that measures air pressure or weight. Bariatric describes the medical treatment of serious overweight—that is, obesity. Bariatric surgery is only employed when other methods of weight loss have been tried and failed. Though stapling the stomach may seem extreme, we now know that obesity greatly increases the risk of heart disease, diabetes, cancer, and stroke, so stomach surgery doesn't just help people look and feel better—it's a potential lifesaver.
