The full answer
Not strictly required, but strongly recommended
A dietitian experienced with celiac disease can help identify hidden sources of gluten, plan balanced meals, and address any nutrient deficiencies — which is often more thorough than navigating the diet changes alone, especially right after diagnosis.
When it helps most
A dietitian is particularly useful in the first few months after diagnosis, when the learning curve is steepest, or later if symptoms persist despite what seems like a careful gluten-free diet — see why symptoms sometimes continue.
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.
