Rapid Stomach Emptying
(Gastric Dumping)

Rapid Stomach Emptying (Gastric Dumping): Overview

Alternative Names: Dumping syndrome.

Rapid gastric emptying happens when the lower end of the small intestine (jejunum) fills too quickly with undigested food from the stomach.  "Early" dumping begins during or right after a meal.  Some people may have both early dumping and delayed gastric emptying due to gastric rhythm disturbances.

Causes and Development

Certain types of stomach surgery that allow the stomach to empty rapidly are the main cause of dumping syndrome.  Patients with Zollinger-Ellison syndrome may also have dumping syndrome.  (Zollinger-Ellison syndrome is a rare disorder involving extreme peptic ulcer disease and gastrin-secreting tumors in the pancreas.)

Signs and Symptoms

Symptoms of early dumping include nausea, vomiting, bloating, diarrhea and shortness of breath.

Diagnosis and Tests

Doctors diagnose dumping syndrome primarily on the basis of symptoms in patients who have had gastric surgery that causes the syndrome.  Tests may be needed to exclude other conditions that have similar symptoms.

Treatment and Prevention

Treatment includes changes in eating habits and possible medication.
