Mary,
yes, in some respects they are treated differently. When I had UC my treatments were mesalamine pills, enemas and suppositories, plus the occasional uceris foam. I would have gone to a biologics;(remicaid, humira, etc), but dysplasia formed and with that I lost my colon.
I do not yet suffer from pouchititis, but I do suffer from cuffitis., so I am back on the canasa.
some folks do well with antibiotic’s, combos, and rotations as well as biologics. You need to work closely with your care team to improve your QOL.
It really does not matter what we call it at this point. If you are suffering, you just want relief and the feeling that your pouch will function well for years to come.
