The main cause of the condition is stomach surgery.  It becomes difficult for the digestive system to control the movement of the food after gastric surgery and it begins to dump the undigested in to the small intestine. Foods rich in sugar, fats and dairy products can lead to the dumping syndrome. The symptoms of the early dumping occur when the undigested food is pushed in to the small intestine while the symptoms of the late dumping occur when the blood sugar level rises or falls.
