Quincy just beat me to it. I was about to ask the same thing - what have results of old biopsies shown? Any comments in them about increased eosinophils?
This is a non-specific finding that could indicate all sorts of things: allergies, as you mention, or parasite, as you mention, but also so-called autoimmune diseases, including UC but including many others as well, can have increased eosinophils in the tissue.
So it may be nothing new, really, or it may indicate you have something going on other than, or in addition to, your UC. Further investigation is warranted, starting with looking at all old biopsy reports.
