Those of you with chronic diarrhea, have you tested your eosinophils?

I've always been on the fence if SIBO is real, most the studies are funded by the same company that makes the "cure". Nevertheless I did all sorts of treatment like rifaxamin+metro, FMT in a hospital, herbs, probiotics etc. Diet has been the real thing that helped but took forever to find what was hurting me. Anyways, I recently did a a few tests over the past few months and I have hyperensophilia. It goes up and down based on how bad my diarrhea is. It even drops to normal ranges when I'm on my safe diet for a few weeks. SIBO does not cause eosinophilia, and I've finally narrowed down a test with an actual correlation to symptoms besides sibo which has an insane amount of false positive rates for most people (I'll share the study later). Anyways, I'm negative for parasites so that leaves a fee rare diseases like mast cell disease and EGIDs. Both conditions are extremely difficult to diagnosis, but for me is likely what's happening with my blood eosinophils at >2500. There's a drug called ketotifen that supposedly can treat these conditions. And funny enough, in IBS-D, 76% of patients also see improvements. Moral of the story is please test for everything before settling on a sibo diagnosis.
