What is Dermatitis
Dermatitis Herpetiformis (DH) is a chronic disease of
the skin marked by groups of watery, itchy blisters that
may resemble pimples or blisters.
The ingestion of gluten (from wheat, rye and barley)
triggers an immune system response that deposits a
substance, IgA (Immunoglobulin A), under the top layer
of skin. IgA is present in affected as well as
unaffected skin. DH is a hereditary autoimmune gluten
intolerance disease linked with celiac disease. If you
have DH, you always have gluten intolerance.
With DH, the primary lesion is on the skin, whereas with
celiac disease the lesions are in the small intestine.
The degree of damage to the small intestine is often
less severe or more patchy than those with celiac
Both diseases are permanent and symptoms/damage will
occur after consuming gluten.
