Mouth sores could suggest celiac disease

June 30, 2009 A new study in the journal BMC Gastroenterology finds a minority of patients with recurrent mouth sores have gluten sensitivity, making evaluation for celiac disease warranted.

Celiac disease is an inherited autoimmune disorder in which the lining of the small intestine is damaged from eating gluten and other proteins found in wheat, barley, rye and possibly oats. Painful open ulcers such as canker sores in the mouth tend to reappear in times of stress and are associated with viral infections, food allergies and other conditions.

In this study, a small group of patients put on a strict gluten-free diet all showed improvement in mouth ulcers within two to six months.
