Great question! Even if some individuals with celiac disease don’t experience immediate villi damage from occasional cross-contamination, it’s still strongly recommended to maintain strict avoidance of gluten. The immune response triggered by gluten can vary between individuals, and even small amounts may cause systemic inflammation or other symptoms, even if intestinal damage isn’t immediately detectable. Additionally, repeated exposure—even at low levels—could lead to cumulative harm over time. Strict avoidance of cross-contamination remains the safest approach to prevent long-term complications and ensure overall health. Everyone’s sensitivity differs, so working with a...

You have one gene for Celiac.  You have a second autoimmune disease, Hashimoto's thyroiditis, which is frequently found at a higher rate with Celiac.  HLA genes carry autoimmune disease genes like Celiac and Hashimoto's and diabetes and others.   You have Celiac symptoms of reacting after gluten.  You said "I am however still suffering from the effects of the gluten challenge (food sensitivities, slight brain fog, weird stool, fatigue, swollen thyroid, bodyaches)."  And your anti-thyroid antibodies increase after gluten exposure.  While tTg IgA does not directly attack the thyroid, gluten exposure does trigger the  immune system to produce antibodies against the...
