Exercise-induced asthma.

Abstract

Exercise-induced bronchospasm is a common condition of patients who have asthma. Its mechanism appears to be related to cooling of the airways. Clinically, it can be managed by pretreatment with beta-adrenergic medications or cromolyn. Measures to protect the airway from excessive loss of heat, such as the use of scarves or participating in indoor activity, are also effective strategies in its management.
