Allergies

Allergies are the body’s exaggerated immune response when it comes into contact with substances or external elements that are generally not harmful to health and that other people do not have a reaction to.

Causes. An allergic reaction is triggered when a specific allergen comes into contact through inhalation, or via the eyes or skin (and in a sufficient quantity), with a person who is sensitive to that allergen.

Symptoms include nasal congestion, sneezing, watery eyes, red eyes and bronchial asthma.

Treatment. The drugs most commonly used to relieve respiratory symptoms are oral antihistamines and nasal steroids for rhino conjunctivitis, and bronchodilators and corticosteroids that are inhaled for asthma.
