Many people experience a strong urge to have a bowel movement shortly after eating. While it may seem unusual, this reaction is more common than you think—and it actually has a name in medical science: the gastrocolic reflex.
What is the Gastrocolic Reflex?

When you consume food, your stomach stretches, which sends signals to your intestines to make room for incoming food by clearing out what’s already there. This usually results in a feeling of urgency to defecate.
According to Dr. Niket Sonpal, a gastroenterologist and adjunct professor at Touro College of Medicine in New York:
“The gastrocolic reflex is more active in some individuals than in others, and it’s especially common in people with irritable bowel syndrome (IBS).”
