Exercise induced asthma: a clinical perspective.

Abstract

Exercise is a very common precipitant of asthma. Inflammation and edema are felt to be important components of the asthmatic response. Heat and water loss from the airway mucosa are most likely important in its pathogenesis, although the exact etiology remains unknown. A good history combined with proper diagnostic testing can usually determine the diagnosis, and prevention is the key to effective management. Although modified training techniques are often helpful, medications are usually needed for both prevention and treatment. While antiinflammatory agents are gaining therapeutic importance, inhaled beta-agonists remain the treatment of choice. With appropriate diagnosis and management, exercise-induced asthma should not limit participation nor performance in athletics for the great majority of the population.
