gas is gas for me. if i eat a food i dont "tolerate" it doesnt give me more or less gas.
on the other hand, for me, irritation comes in the form of butt burn, and a feeling of inflammation/the feeling like there is a tennis ball sized flaming rock lodged in my rectum.
this lasts anywhere from a day to three days. and occasionally the whole experience will throw me off for a couple weeks. (though i dont believe my issues are pouchitis, because they seem to resolve themselves).
it does increase my frequency though not necessarily consistency (my normal frequency is 7-9 per 24hr period, and when irritated can be anywhere from 9-14). i think the frequency increase is a result of inflammation, which may be making the pouch less spacious, OR its a result of my butt hole being shy because it knows its going to burn, therefore i dont get to empty as much in one trip.
