Gastric dumping syndrome
Gastric dumping syndrome is a condition in which there is a rapid stomach emptying of chyme into the small bowel. It usually occurs as a complication after gastric surgery, which can make the stomach smaller or result in the destruction or bypass of the pyloric sphincter. This causes the hyperosmolar chyme (usually after a carbohydrate-rich meal) to move too quickly from the stomach to the small intestine and causes fluid retention in the intestine due to the osmotic gradient. This can cause problems such as cramps, nausea, vomiting, and diarrhea.
