A celiac disease diagnosis means one thing changes everything: gluten. This is the calm, plain-English companion for the first months of the new normal. It explains the autoimmune mechanism damaging your small intestine, what the tTG-IgA test and biopsy actually confirm, why going gluten-free before testing can hide the diagnosis, and how to actually avoid cross-contamination. It covers nutrient deficiencies worth watching and the warning signs of complications. No jargon. No fear. No filler. Just what you actually need, in the order you need it, with clear tables, checklists, and the exact questions to bring to your next appointment.
