Before Going Gluten-Free: Ask About Celiac Testing
If you are considering a gluten-free diet because of ongoing digestive symptoms, speak with your clinician about testing first. Changing what you eat before the assessment can make some tests harder to interpret and may delay a clear diagnosis.
What to do next
- Tell your clinician what symptoms you have, how long they have lasted, and whether relatives have celiac disease.
- Celiac evaluation often includes blood tests and sometimes a small-intestinal biopsy.
- Do not begin a gluten-free diet before testing without discussing it; avoiding gluten can affect results.
- If you have already stopped eating gluten, tell the team exactly when rather than restarting it on your own.
Make the plan fit your health needs
Do not deliberately challenge yourself with a food that has caused a severe allergic reaction. Celiac disease, wheat allergy, and other food-related symptoms are different conditions. Get medical advice for unexplained weight loss, bleeding, or worsening illness.
Put it into practice
A useful message is: “I stopped wheat two weeks ago because of symptoms. Will that affect the tests you ordered?” Bring a brief food and symptom history. Your clinician can decide whether additional evaluation or a supervised dietary plan is appropriate.
Notes for your next visit
