 Dermatitis herpetiformis does not usually cause complications on its own, without being associated with another condition.Complications from this condition, however, arise from the autoimmune character of the disease, as an overreacting immune system is a sign that something does not work well and might cause problems to other parts of the body that do not necessarily involve the digestive system.Gluten intolerance and the body's reaction to it make the disease more worrying in what concerns the possible complications.
