With the term skin allergies, we refer to appearance of allergic symptoms on the skin, which probably is the most common allergy display area. Practically, any type of allergies (with exception of respiratory allergy) can appear either exclusively as skin allergy or with a combination of symptoms from the skin and other organs.

Thus, food allergy, drug or bee or wasp sting allergies can appear either as exclusively skin allergy (with the appearance of a skin rash that called urticaria), or as a combination of skin allergy with symptoms on other organs, like the respiratory, the digestive and the circulatory system (blood pressure). Especially when the skin allergy (urticaria) is combined at the same time with symptoms on other organs, then the disease is called systemic anaphylactic reaction (anaphylaxis).
