What is Dumping Syndrome?

Dumping syndrome is a postprandial vasomotor and gastrointestinal symptom complex that occurs after gastric surgeries (gastrectomy, gastric bypass, pyloroplasty) due to rapid emptying of stomach contents into the small intestine.

Early dumping occurs 15-30 minutes after eating and arises when hyperosmolar contents draw fluid into the small intestine. Late dumping occurs 1-3 hours later and is characterized by reactive hypoglycemia.

Diagnosis is generally made by clinical evaluation; oral glucose tolerance test and gastric emptying studies are supportive. Treatment begins with dietary changes (small frequent meals, carbohydrate restriction), followed by medical therapy (acarbose, octreotide), and rarely surgical revision.
