Atopic diseases are those caused by an allergic reaction caused by the activation of immunoglobulin E (IgE). These come into action before agents harmless to the majority of the population, such as pollen, mold, animal hair and mites, for example.
Some examples of atopic diseases are: Allergic rhinosinusitis, asthma, allergic conjunctivitis, urticaria and atopic dermatitis.
In most cases, in addition to the individual, someone else in the family suffers from allergies. These should be controlled with the use of antihistamines and keeping as far as possible from the allergy triggering agent. When this is not possible, one can try taking the so-called "vaccines", injections that relieve allergic crises, sometimes even eliminating them.
Some symptoms of an allergic reaction are: coughing, sneezing, redness and itching of the skin and / or eyes. Seek medical attention if symptoms persist.
