In briefMany people suffer from asthma MH and other allergic conditions. Participating in sports exposes these people both to specific allergens and to nonspecific factors that will influence the presentation of their allergic symptoms. Allergy patients experience both beneficial and deleterious effects of sports participation. For the patient whose symptoms are triggered or aggravated by sports activity, treatment should focus on avoiding or modifying the triggering factors either through physical means or through the use of pharmacologic agents.
