Dumping syndrome is a constellation of gastrointestinal and vasomotor symptoms resulting from changes in the anatomy and physiology of the stomach created by gastric surgery. Dumping syndrome is frequently attributed to the rapid emptying of gastric content into the small bowel. However, the etiology of dumping syndrome is multifactorial. Severe dumping can be complicated by malnutrition and it can be associated with poor quality of life. Most patients with dumping syndrome can be treated conservatively with dietary modifications. Octreotide is the most effective drug therapy for patients with incapacitating symptoms. Those patients who failed medical therapy may be considered as surgical candidates. The aim of this article is to review the clinical features and pathophysiology of dumping syndrome in addition to providing guidelines for its management.
