Step 1

There are many types of allergic reactions. However, there are certain allergens that people react to most often. These include dust, insect bites and secretions, various medications, food (eggs, nuts, milk, citrus fruits, etc.), mold, animal hair and saliva, pollen from flowering plants, tissues, and much more.

Step 2

Varieties of allergic reactions are bronchial asthma, allergic rhinitis, conjunctivitis and otitis media, and urticaria. They appear depending on which organ responds with inflammation to the stimulus. For example, allergic rhinitis or bronchial asthma begins with inflammation of the respiratory system, and if the eyes become inflamed, allergic conjunctivitis may occur. Hives and dermatitis indicate an allergic skin reaction. Sometimes inflammation can manifest itself in several types of reactions at once and cause anaphylactic shock.

Step 3

Depending on the type of allergy, concomitant symptoms are distinguished. Allergic asthma manifests itself in the form of cough, shortness of breath, breathing problems; allergic rhinitis - in the form of sneezing, itching of the nasal mucosa, discharge, congestion. Conjunctivitis is expressed by redness and swelling of the eyes, lacrimation, itching of the eyelids. With urticaria, a small and frequent rash occurs, and rashes with atopic dermatitis are accompanied by severe itching. Anaphylactic shock causes clouding or loss of consciousness, respiratory arrest, etc.

Step 4

The cause of a particular allergic reaction can only be determined by a doctor on the basis of a thorough examination and analysis. If you know exactly what is causing the allergic reaction, you should limit contact with this object. Allergies are treated with special medications prescribed by a doctor.
