adjustable gastric banding

adjustable gastric banding

(ă-jŭs′tă-bl) A bariatric surgical treatment for obesity in which a Silastic belt encircles the proximal portion of the stomach, restricting the flow of food. The rest of the gastrointestinal tract is left unmodified. The belt initially permits the proximal stomach to hold just an ounce of food. The restriction gives patients a feeling of premature fullness after a small meal, which keeps them from overeating. It can be loosened after significant weight loss has occurred to permit slightly increased food intake. Weight loss with gastric banding, which results purely from limitations on food intake, tends to be less than what can be achieved with surgery, e.g., Roux-en-Y gastric bypass. Relatively common complications of banding include nausea and vomiting, erosion of the band into the stomach, and wound infections. Some patients learn to eat slowly but continuously and fail to lose weight..
