Gastric dumping syndrome

Summary of Gastric dumping syndrome
Dumping is a phenomenon usually caused by the destruction or bypass of the pyloric sphincter. It is frequently attributed to the rapid emptying of hyperosmolar chyme (particularly carbohydrates) into the small bowel, leading to net fluid retention due to the osmotic gradient, and release of one or more vasoactive hormones.
