Digestive Disorders

Correlation Between Eating and Evacuating

09/07/2011

Question:

I have not seen this question anywhere. After eating, within 30 minutes, I must evacuate stool. What is correclation between eating and feeling the need to evacuate? This is embarrassing if we are eating out. Is there something about the sphincter muscle involved? What triggers the colon to start evacuating that fast. I also have a chronic non healing anal fissure. Thank you.

Answer:

That is a form of irritable bowel. There is a gastro (stomach)- colic (colon) communication which when food hits the stomach tells the colon to start contracting. You just have a strong reflex. No meds for that. Imodium may help when eating out. Anal fissures which do not heal usually need surgery.
