I don't show typical signs for pouchitis. My symptoms are more like yours. I however don't usually have an appetite but that comes from forcing myself to eat and not lose weight. I had the same concerns as it's not typical signs.
Definitely get checked out. I have been doing much better after adding cbd oil(ingested) to my Visbiome. My doctor thinks that the cbd is keeping inflammation down and allowing the Visbiome to get everywhere and keeping the pouchitis bacteria flushed out.
Good luck
