There are various symptoms, though increased urgency and leakage seem to be the ones most commonly mentioned here. The best way to tell is if your symptoms clear up almost miraculoously with a course of Cipro. Many GIs will prefer to do a pouchoscopy first, especially if your patterns aren't clear yet.

I have had pouchitis just a few times. If I get thin, fast watery output when I intubate and it last for more than 2 or 3 days - then I take a round of Flagyl ( 250 mg 3x daily for 14 days. ) Works well for me. My first doc scoped me. Found just a bit of redness. I had a moderate case. Some will have bleeding. Maybe a bit of a fever and just feel crummy.
