Dumping Syndrome

Q) What is the mechanism of action of Octreotide in dumping syndrome ?

a) Acceleration of gastric emptying

b) Shortening of small bowel transit time

c) Inhibition of endocrine secretions

d) All the above

Answer: C

  • Octreotide alleviates both early and late dumping symptoms through inhibition of hormone mediators.
  • It also delays gastric emptying time and inhibits splanchnic vasodilation.

Shack, 8th, 722.

  • These peptides not only inhibit gastric emptying but also affect small bowel motility so that intestinal transit of the ingested meal is prolonged.

Sabistan, 21st, 1217.


  • Late dumping occurs 1 to 3 hours after a meal and is less common.
  • The basic defect of late dumping is also rapid gastric emptying; however, it is related specifically to carbohydrates being delivered rapidly into the proximal intestine.
