Q

Can celiac disease cause watery blisters on the skin?

Blisters on the skin (part of the dermatitis herpetiformis version of celiac disease) are an inflammatory result due to a deposition of anti-tTG antibodies in the skin. In fact, recent studies have demonstrated that IgA antibodies against epidermal transglutaminase 3 play an important role in the pathogenesis of dermatitis herpetiformis. See Nakajima K.
