What is Dumping Syndrome?
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 gastric surgery patients by consumption of simple carbohydrates (sugar, or some starches) or carbs with a high glycemic index.
Types of Dumping Syndrome
There are two variants of rapid gastric emptying: early and late dumping. "Early" dumping typically starts during or immediately after a meal. Early dumping symptoms include: abdominal cramps, bloating, palpitations, nausea, vomiting, bloating, diarrhea, and shortness of breath. By contrast, late dumping typically occurs 1-3 hours after eating. Symptoms of late dumping include: weakness, dizziness and fatigue.
What Causes Dumping Syndrome?
Bariatric surgery is the main cause of dumping syndrome because it changes the anatomy and normal digestive functioning of the stomach and also (in the case of gastric bypass) the small intestine. It may also reduce the amount of digestive juices from the stomach and pancreas. Another, much rarer cause of dumping is Zollinger-Ellison syndrome.
Treatment For Dumping Syndrome
Patients who suffer from rapid gastric emptying need to change their eating habits and consume several small meals a day - preferably including foods that are low in carbs, especially refined sugars. In addition, they should not drink liquids with their food. Lastly, patients should ensure that all food is chewed thoroughly.
Dumping Syndrome - Bad Eating Indicator After Bariatric Surgery
Dumping syndrome is not a big health risk. Rather, it's an indicator to gastric surgery patients that they are (1) eating too much, or too fast; (2) eating too many sugary carbs. In practice, most bariatric patients do not experience more than 2-3 episodes of serious dumping.
