I'm so sorry no one has responded to this because I have the same question

Pouchitis, cuffitis, SIBO.

All three share similar symptoms.

I have had cuffitis and SIBO, but not pouchitis. Symptoms I have had include frequency, spasms, blood, and a constant sense of need to go (tenesmus).

I am sure the pouchitits sufferers will respond, but a pouchoscopy with biopsies will reveal the real issues and provide a sound diagnosis for treatment.

pouchitus and SIBO are treated with antibiotics and cuffititis is usually treated with mesalamine either oral or suppositories.

All three are well documented on this site.

Both pouchitis and cuffitis can cause pain and urgency. Cuffitis acts more like UC and is more prone to bleeding than pouchitis, though both can bleed. As New577 wrote above it’s best to get a proper diagnosis, and symptoms alone may not be enough to tell them apart.
