Notice whether you get symptoms after eating gluten-containing foods
Track common symptoms such as bloating, gas, diarrhea, constipation, stomach pain, nausea, fatigue, headaches, brain fog, joint pain, or skin rash
Keep a food and symptom diary for several weeks
Try not to remove gluten before medical testing
See a doctor to rule out celiac disease and wheat allergy
Ask about blood tests for celiac disease
Ask whether genetic testing or an endoscopy is needed
Consider a supervised elimination and reintroduction of gluten
Monitor whether symptoms improve off gluten and return when gluten is reintroduced
Get medical advice if you have weight loss, anemia, severe pain, vomiting, or blood in stool
