1. It is necessary to have it diagnosed. An allergy is a disease that must be diagnosed and the causative allergen identified, although on many occasions this is not possible. To know what causes an allergy is very useful to avoid it or take measures to minimize our exposure to it, as well as taking preventive medicine and opt to specific immunotherapy vaccines.

2. Keep it under control. We must not consider an allergy as a minor ailment. Breathing allergies are usually long-lasting, making daily activities uncomfortable, disturbing sleep, social activities, leisure time, concentration at work or school and generally diminishing our quality of life. On the other hand, an allergy frequently evolves from slight expressions (allergic conjunctivitis and/or rhinitis) to more severe forms (bronchial asthma). This is considered a natural evolution of the disease. Finally, some allergic reactions can be very severe or even fatal, as with anaphylactic shocks.
