AbstractAsthma is a chronic inflammatory disease that causes hyperresponsiveness of the bronchial tree, with reversible airflow obstruction. The condition places a significant burden on our healthcare system. Chronic asthma can cause remodelling of the airway. Patients suffering from asthma should be aware of the signs and symptoms thereof, as well as the factors that can precipitate an asthmatic attack. Asthma is a chronic inflammatory disease; the diagnosis of asthma is based on identifying both a characteristic pattern of respiratory symptoms and variable expiratory airflow limitation. Treatment is based on how the patient presents and includes bronchodilators, inhaled corticosteroids and mast cell stabilisers. This article provides an overview on the diagnosis, characterisation and treatment of asthma.
