Exoallergy is an allergic reaction of the body to substances coming from outside.
Exoallergens are substances that cause exoallergy. These include plant pollen, animal hair, medicines, food products, household chemicals and other environmental components. Once in the human body, exoallergens trigger an immune response, which manifests itself in the form of allergic reactions.
The main symptoms of exoallergy include hives, swelling, itching of the skin, runny nose, sneezing, lacrimation, and shortness of breath. Gastrointestinal disorders may also occur. The severity of symptoms depends on a person's individual sensitivity to a particular allergen.
Diagnosis of exoallergy includes medical history, skin tests, and blood tests for allergen-specific antibodies. Treatment is aimed at eliminating contact with the causative allergen and using antihistamines. In severe forms of exoallergy, desensitizing therapy may be required.
Prevention of exoallergy involves identifying and eliminating contact with allergens, as well as increasing the body’s resistance to allergies. Maintaining hygiene and ventilation of premises is important.
