Dumping Syndrome Flashcards
(20 cards)
What is Dumping Syndrome?
A complication of gastric surgery characterized by rapid gastric emptying into the small intestine.
What are the two types of Dumping Syndrome?
Early and Late Dumping Syndrome.
What causes Dumping Syndrome?
Loss of normal pyloric sphincter control after gastrectomy or gastric bypass.
What is the typical timing of early Dumping Syndrome symptoms?
Within 15–30 minutes after eating.
What symptoms are associated with early Dumping Syndrome?
Abdominal pain, diarrhea, nausea, dizziness, tachycardia, flushing.
What is the pathophysiology of early Dumping Syndrome?
Osmotic fluid shift into intestines causes hypovolemia and autonomic symptoms.
What is the typical timing of late Dumping Syndrome symptoms?
1–3 hours after eating.
What symptoms are associated with late Dumping Syndrome?
Hypoglycemia, weakness, sweating, confusion, dizziness.
What is the pathophysiology of late Dumping Syndrome?
Exaggerated insulin release due to rapid glucose absorption.
How is Dumping Syndrome diagnosed?
Clinical diagnosis; occasionally confirmed with glucose tolerance testing or gastric emptying studies.
What is the first-line management for Dumping Syndrome?
Dietary modification is first-line.
What dietary modifications help manage Dumping Syndrome?
Frequent small meals, high-protein, low-carbohydrate, avoid simple sugars, drink fluids between meals.
What medications can be used if dietary changes fail?
Octreotide (somatostatin analog).
What surgical history is commonly associated with Dumping Syndrome?
Partial gastrectomy, gastric bypass, or fundoplication.
What complication of bariatric surgery is Dumping Syndrome similar to?
Postprandial hypoglycemia (late Dumping).
How can blood glucose levels help differentiate early vs late Dumping?
Early: normal glucose; Late: hypoglycemia.
Is hypoglycemia more common in early or late Dumping Syndrome?
Late Dumping Syndrome.
Which hormone surge is involved in late Dumping Syndrome?
GLP-1 (glucagon-like peptide-1).
What role does gastric emptying play in Dumping Syndrome?
Accelerated gastric emptying causes rapid nutrient transit.
What is the long-term prognosis for Dumping Syndrome with dietary control?
Most improve significantly with diet; rare cases may need medication or surgery.
