Has anyone experienced tiny amounts of gluten adding up over time ending with a sudden reaction "out of nowhere"?
My son (gluten and many other intolerances) has had an intense reaction after being symptom-free for 6 months. Since there is no obvious source of gluten, I am wondering if he could have ingested gluten in tiny amounts over a long period of time, for example from "gluten-free" foods (gluten-free Rice Krispies etc.) or from sticking his fingers into his mouth at school.
Is it possible to have a full-blown reaction once the accumulated amount reaches a certain level?
Thanks for any input!
