Celiac is an autoimmune disease that affects one out of every 133 people in the US. People with this condition can't eat foods that contain gluten.
Researchers also looked at inflammatory bowel disease.
Chronic headaches were reported by 56 percent of gluten sensitive participants, 30 percent of those with celiac disease, and 23 percent with inflammatory bowel disease.
Experts say it's possible the general inflammatory response from these disorders may also affect the brain and result in migraines.
