For some people, celiac disease causes an itchy, blistering rash known as dermatitis herpetiformis.
Dermatitis herpetiformis is often associated with changes to the lining of the small intestine identical to those of celiac disease, but the disease may not produce noticeable digestive symptoms.
It may begin with an intense burning sensation around the elbows, knees, scalp, buttocks, and back. Clusters of red, itchy bumps form and then scab over.
It often first occurs in the teenage years and is more common among men than women. The rash usually clears with a gluten-free diet but can also be treated with medication.
