Gastric dumping syndrome, or rapid gastric emptying is a condition where ingested foods bypass the stomach too rapidly and enter the small intestine largely undigested.
It happens when the small intestine expands too quickly due to the presence of hyperosmolar contents from the stomach. This causes symptoms due to the fluid shift into the gut lumen with plasma volume contraction and acute intestinal distention.
Treatment: People who have gastric dumping syndrome need to eat several small meals a day that are low in carbohydrates, avoiding simple sugars, and should drink liquids between meals, not with them. Fiber delays gastric emptying and reduces insulin peaks.
