What is 'dumping' and how can I prevent it?

The dumping syndrome occurs after the stomach is emptied too rapidly. By eating or drinking too many calories too fast at the same time, the small intestine may not be able to process the calories quickly enough.

Symptoms can range from fatigue, sweating, frequent yawning and light headedness, to trembling, nausea, bloating, diarrhea, severe vomiting, appetite and strong sense of non-being. Usually this goes on for half an hour to an hour, depending on the person and the severity of the symptoms.

By eating small amounts of food, spread throughout the day, usually the attacks can be avoided. It is best to limit drinking and eating solid food at the same time.
The dumping syndrome only takes place after a gastric bypass. Most people never experience dumping: it occurs to one in three patients.
