Start with your primary care provider. They can order:
-
Blood tests for celiac disease (tTG-IgA, EMA, etc.)
-
Genetic testing (HLA-DQ2 and HLA-DQ8)
-
Referral to a gastroenterologist for possible endoscopy
Step 2: Keep a Detailed Food Diary
Write down:
-
What you eat
-
When you eat it
-
Any symptoms that follow
-
How severe they are
Step 3: Consider an Elimination Diet (Under Guidance)
If testing is negative but symptoms persist, a supervised elimination diet can help identify triggers.
Step 4: Work with a Dietitian
If you do need to go gluten-free, a dietitian can help you do it healthfully—because gluten-free doesn’t automatically mean healthy.
