Itchy rash
Dermatitis herpetiformis can be caused by celiac disease. This is a rash that is itchy and blistering on your elbows, knees, or buttocks. This rash affects around 17% of patients with celiac disease and is one of the signs that leads to a diagnosis. It may also appear after a diagnosis as a result of poor treatment adherence.
The additional digestive symptoms that are frequently associated with celiac disease are rarely seen by those who develop this skin rash. Other potential causes of an itchy skin rash besides celiac disease include:
- eczema
- psoriasis
- dermatitis
- hives
