WHAT IS ALLERGIC RHINITIS?
Allergic rhinitis characterised by an inflammation of the lining of the nasal cavity. This is due to the immune system being sensitised and then overreacts to irritants in the environment. This inflammation is typically characterised by a blocked nose, rhinorrhoea, sneezing and itching. It can be classified as intermittent (symptoms less than four days per week or less than four weeks) or persistent (symptoms more than four days per week or more than four weeks).
