Doctor shares what it means if you always need to poo immediately after you eat (it isn’t just IBS)

Beyond IBS: Other Possible Causes

While IBS can cause post-meal bowel urgency, other factors might be at play:

1. Dietary Choices – Foods high in fat, caffeine, or sugar can intensify the gastrocolic reflex. Large meals can also trigger a stronger response.
2. Infections or Gut Inflammation – Gastrointestinal infections, food intolerances, or inflammatory conditions like colitis can increase urgency.
3. Hormonal and Nervous System Factors – Stress and anxiety can stimulate bowel activity, making the reflex more pronounced.
4. Colon Disorders – Conditions like chronic constipation followed by overflow or rapid transit syndromes may cause frequent post-meal urges.

When to Seek Medical Advice

Most instances are harmless, but you should consult a doctor if you notice:

• Persistent diarrhea or blood in the stool
• Unexplained weight loss
• Severe abdominal pain
• A sudden change in bowel habits
