Also called "rapid gastric emptying", dumping syndrome occurs when the lower section of the small intestine (jejunum) fills up too quickly with undigested food from the stomach, causing unpleasant digestive effects. Dumping syndrome can also be triggered in bariatric surgery patients by consumption of simple carbohydrates (sugar, or some starches) or carbohydrates with a high glycemic index.
Early dumping syndrome vs. late dumping syndrome
Early dumping syndrome, which happens almost to all bariatric surgery patients, lasts from 3 months to 9 months. Late dumping syndrome happens 2 years after gastric bypass, and can be very frustrating for those patients.
At Johns Hopkins, our weight loss specialists will treat your dumping syndrome with different diets to avoid this unpleasant side effect of bariatric surgery.
