Triggers for respiratory allergies are substances found in the air. They can be perennial allergens (causing symptoms throughout the year) or seasonal allergens (producing symptoms, mostly during the spring).
 
These allergens include: house dust mites, mould (due to humidity), different types of pollen (olive, grasses, cypress, parietaria…), animals etc.
 
To determine the allergen causing the symptoms, a specialist consultation is required, specialists employ different tests to discover which allergens are involved in the reaction

Aeroallergens prick test: exposing the patient’s skin to different allergens to see which one(s) trigger symptoms.
 
Molecular diagnosis: through the extraction of a small blood sample.
 
Forced spirometry and other respiratory tests:to measure lung function and establish an asthma diagnosis.

Once the problem has been identified, there are several ways to deal with symptom control, both in the short and long term.
 
The different treatment options include: antihistamines, nasal corticosteroids, eye drops, different types of inhalers, biologic drugs and immunotherapy (vaccine) against the responsible allergens.
