Asthma is a lung disorder characterized by intermittent, paroxysmal airflow obstruction due to bronchoconstriction and bronchial inflammation. A variety of stimuli may trigger an asthmatic episode; remission may occur spontaneously or only after bronchodilator therapy. Severe, acute asthma is life-threatening, even though it usually responds to initial bronchodilator therapy. It usually requires hospitalization and intensive therapeutic intervention. It can be fatal.
