she was scoped for the Celiac diagnoses? This can still be a congenital defect of the GI track.
A little more about Eosinophilic Esophagitus. Food or airborn "trigger" activate eosinophil production, this can cause damage for 12 days. (That is why a 4 day rotation won't help you out much is this is the situation.) You need the reaction happening to get diagnosed, and this can be a seasonal airborn allergen. Eosinophils, the white blood cells usually reserved for fighting parasite infection, damage normal healthy tissue. A biopsy must be done because some of the eosinophils are embedded in "normal" looking tissue. (The doctor also must order the pathologist to test the eosinophil count.) The damage looks like creamy spots., furrowing, Schatzi rings. Does your child have occassional spotted throat with bad breath? Little ones don't complain about the throat hurting ~ they just say the stomach hurts. Get back to the doctor before any seasonal part of the puzzle is missing. This is not easy to get diagnosed and is now proven to be connected to Celiac.
