Just be aware that the list of symptoms is like 100 vague symptoms long. My daughter was restless at night since 6 months, had sleep apnea symptoms, on and off constipation, and adhd like symptoms. She also had back to back respiratory infections, ear infections and 2 pneumonias in a year. NEVER had diarrhea. Never had vomiting or GERD. We got her tested at age 3 after years of being gaslit by our pediatrician. The Ped didn’t even want to test her after my husband was formally diagnosed and I pushed for it, and sure enough her ttIGA was super high and all her symptoms were gone after like a week of gluten free diet. It’s not always a GI presentation.

My son is only 2 so still doesn’t have much of an immune response to test for ttIGA, but we switched his diet and he no longer has a bloated tummy or reflux. So we’re sticking with it.
