The full answer
A prepared translation card is the most reliable approach
Because celiac disease isn’t always well understood internationally — and “gluten-free” doesn’t translate cleanly everywhere — a printed or digital card explaining the condition and specific ingredients to avoid, in the local language, is one of the most effective travel tools.
Where to find or make one
Several celiac and travel organizations offer free downloadable translation cards for common languages — searching for “celiac disease restaurant card” plus your destination language is a good starting point before a trip, alongside the general prep covered in traveling safely with celiac disease.
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.
