toilet use immd after eating.

I have always wondered why i sometimes have to use the toilet just after eating certain foods. I have always believed it to take 8 hrs  give or take for me to eat, digest and then evacuate. The other day i ate chinese food which I happen to love and had to nearly run to the bathroom. What is happening that makes me have to" GO NOW" after eating certain foods. Thank you mc

If you don't feel any skin/lips/throat itching, and no dizziness/anxiety...related to this urgency...than it seems you get irritated by certain foods what occurs in the so called irritable bowel syndrome (IBS). The food you excrete is probably from "the previouis day"(since in most cases it takes more than 24 hours for food to travel all the way) but bowel movement is triggered by the food that comes in your stomach (exaggerated gastro-colic reflex). The triggering food/substance may be anything...may be some specific additive, so after all incidents, try to make a list of all foods in the meal, or if it is commercial product, write down ingredients...

If you do experience some itching, it's likely food allergy.
