Symptoms develop as a result of inhalation of allergens by a sensitised person. Watery secretion, nasal obstruction (experienced as a sense of blocked nose), itching and sneezing appear within a few minutes following contact with an allergen.
There is also a risk of acute and chronic sinusitis. Exacerbation of symptoms depends on the individual characteristics of the allergy sufferer and the concentration of allergens within the home. Severe cases of chronic allergic rhinitis may lead to sleep disorders and reduced daily physical activity and cause difficulties in concentrating on learning and work. A year-round presence of sensitisation symptoms due to constant exposure to household allergens is a typical sign of allergic rhinitis. In order to distinguish this type of allergy from a common cold caused by viral infection, attention should be paid to the duration of the symptoms. Viral rhinitis usually lasts for 10 days.
Allergic rhinitis is the most common non-infectious disease of the upper respiratory track. Allergic rhinitis may occur together with other allergic diseases such as: asthma, allergic conjunctivitis, and atopic dermatitis.
