The full answer
Yes — this is one of the main reasons family screening matters
Just like in the general population, celiac disease can be silent in family members — someone can test positive and have measurable intestinal damage while feeling completely fine.
Why testing shouldn't wait for symptoms
This is precisely why doctors recommend testing at-risk relatives proactively rather than waiting for symptoms to appear — untreated silent celiac disease still carries real long-term risks like nutrient deficiencies.
Important context
Individual symptoms, reactions, medical histories, food products, and local labeling rules can vary. Community experiences are not medical evidence.
For personal medical decisions, diagnosis, testing, or treatment, consult a qualified healthcare professional.
