Loose stool once every week or two, gas, rumbling, etc

[tommytuba]

Hello there. My situation is this: For one or two days out of every month I'll have loose stools / watery / diarrhea. This nastiness is book-ended by gas, rumbling, etc. Should I be concerned? I mean, if it's something that comes and goes. Thing is, I'm trying to determine connections between certain food and these "outbursts" and think perhaps sweeteners, coffee, fats, but nothing really jumps out or strikes me as a direct correlation. I'd just like to know what's going on -- this "stuff" started really 3-4 months ago and comes back every week or two for a day or two. No other symptoms -- no blood -- no jaundice -- no other complaints whatsoever -- just ... THIS.
