Gastric band. Coloured frontal X-ray of the abdomen of a 37-year-old woman, showing a gastric band fitted internally around the stomach to treat obesity. This band (ring) restricts the amount of food a patient can eat and helps weight loss. The tube leading from the band (to right of image) links to an access port under the skin and allows the band to be adjusted.
