What causes dermatitis herpetiformis?

ANSWER

If you have celiac disease and eat gluten, your intestines make an antibody called IgA in response. This chemical flows into your bloodstream and builds up in blood vessels under your skin. It triggers the DH rash.

This condition is rare in children. It usually shows up for the first time when you’re between 30 and 40 years old. Men tend to get it more often than women. It’s most common in people of European descent and rare among African-Americans and Asian-Americans.
