Dumping syndrome occurs in many gastric bypass patients when sweet foods like juice, soda, sugar sweetened beverages, cakes, cookies and pies are eaten. The food passes too quickly into the small intestine and causes symptoms such as: nausea or queasiness, a sense of fullness accompanied by discomfort, cramping, diarrhea, general weakness, profuse sweating, vomiting, and heart palpitations (an increase in heart rate).
Most patients experience a combination of these symptoms. Usually the symptoms will subside in about an hour. Most patients find the symptoms are alleviated after they lie down for a while. Dumping syndrome is not dangerous, but it is quite unpleasant.
Some patients “eat through” the dumping syndrome and they are eventually able to tolerate calorie dense foods in smaller quantities. Given this is a lifestyle change, it is important to avoid these calorie dense foods from the beginning and develop healthier alternatives to eating.
