Why do I have to pass stools soon after breakfast?

I am 23 years old. For the past two years, my digestive system is giving me problems. I am having motion problem only in the mornings. If I have my breakfast, I pass stools within 10 minutes. This happens only when I take breakfast. I don't know why this is happening only in the morning. I am fine the rest of the day.

 

You appear to have a prominent gastro-colic reflex. I suggest you cut down milk intake in the morning (you may have lactose intolerance). If the symptoms persist, take isabgol husk (one tablespoonful in morning with water).
