Dumping syndrome is due to all except:
Dumping syndrome Signs and symptoms arise from the rapid emptying of hyperosmolar gastric contents into the small intestine, resulting in a fluid shift into the gut lumen with plasma volume contraction and acute intestinal distention.

Early dumping takes place 15-30 minutes after meals and consists of crampy abdominal discomfo, nausea, diarrhea, belching, tachycardia, palpitations, diaphoresis, lightheadedness, and, rarely, syncope.
