Allergology is a medical speciality that studies, diagnoses and treats diseases that have developed as a result of a immune hypersensitivity reaction to certain substances (allergens).

It includes diseases affecting the breathing, skin, digestion or the whole body.

Many of these diseases are chronic, which means that patients must be controlled over long periods.

The Allergology Service cares for patients with the following diseases: Anaphylaxis, Conjunctivitis, Rhinitis, Bronchial asthma and related diseases, Food allergies, Drug allergies, Latex allergies, Reactions to hymenoptera insect bites, Atopic dermatitis, Contact dermatitis, Urticaria/Angioedema, Hereditary angioedema, Mastocytosis, Diseases associated to eosinophilia.

The Evaluation process consists of medical records and a physical examination.

Individualised testing depending on the patient’s disease.

Once this process is complete and the diagnosis has been given, the allergologist informs the patient, establishes the treatment and schedules the next visit, if follow-up is required.
