Are the symptoms of exercise-induced asthma always apparent, and if not, how can physicians diagnose the condition? Can exercise-induced asthma exist independently, or does it always signify an underlying asthmatic condition? Host Dr. Ketan Sheth discusses the pathogenesis of and treatments for exercise-induced asthma with Dr. William Silvers, clinical professor of medicine at the University of Colorado School of Medicine. Dr. Silvers will explain the phenomenon that the seemily innocuous food celery can specifically cause exercise-induced allergic reactions.
