Exercise-induced bronchoconstriction (EIB) occurs when the airways narrow as a result of exercise. This condition has been referred to as exercise-induced asthma (EIA); however, this term is no longer preferred. [1] While exercise does not cause asthma, it is frequently an asthma trigger. [1]
More generally termed exercise-induced asthma, the preferred and more accurate term exercise-induced bronchoconstriction better reflects underlying pathophysiology.It is also preferred due to the former term giving the false impression that asthma is caused by exercise.
Exercise-induced asthma, technically called exercise-induced bronchoconstriction, or EIB, can make working out feel downright painful, if not altogether impossible. A narrowing of the airways that ...
Exercise can trigger bronchoconstriction both in people with or without asthma. [116] It occurs in most people with asthma and up to 20% of people without asthma. [116] Exercise-induced bronchoconstriction is common in professional athletes. The highest rates are among cyclists (up to 45%), swimmers, and cross-country skiers. [117]
Bronchospasm or a bronchial spasm is a sudden constriction of the muscles in the walls of the bronchioles. It is caused by the release (degranulation) of substances from mast cells or basophils under the influence of anaphylatoxins. It causes difficulty in breathing which ranges from mild to severe.
Exercise-induced asthma is common in asthmatics, especially after participation in outdoor activities in cold weather. Occupational asthma – an estimated 2% to 5% of all asthma episodes may be caused by exposure to a specific sensitizing agent in the workplace.
An exercise routine that works is one that works for you and your schedule. Being a weekend warrior can provide flexibility in how and when you get your exercise.
Image of aspirin which can be a trigger for asthma in some patients. Aspirin induced asthma, or aspirin-exacerbated respiratory disease, refers to situations where the use of aspirin worsen the asthma conditions. [34] Other non-steroidal anti-inflammatory drugs (NSAIDs) that inhibits the enzyme, cyclooxygenase-1, may also lead to an asthma attack.
