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 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]
Exercise induced asthma is common in most asthma patients. [29] ... It may worsen the condition of asthma as it is an irritant and induces bronchoconstriction.
They are taken 10–15 minutes before exercise. The bronchodilation begins few minutes after inhalation of short-acting β 2-agonists and lasts from 4 to 8 hours. [8] [9] Long-lasting β 2-agonists are discouraged in treating acute exercise-induced asthma, because their chronic use might mask poorly controlled asthma. [10]
It is used to treat asthma, including asthma attacks and exercise-induced bronchoconstriction, as well as chronic obstructive pulmonary disease (COPD). [8] It may also be used to treat high blood potassium levels. [9] Salbutamol is usually used with an inhaler or nebulizer, but it is also available in a pill, liquid, and intravenous solution.
The medical uses for Cysteinyl-leukotriene type 1 receptor antagonists are for chronic and prophylactic treatment of asthma. [3] [9] [10] Other indications have been approved by the FDA for montelukast and they are used for the prevention of exercise-induced bronchoconstriction (EIB), relief of symptoms of allergic rhinitis (AR) that is for relief of seasonal allergic rhinitis and perennial ...
Exercise-induced laryngeal obstruction (EILO) is a transient, reversible narrowing of the larynx that occurs during high intensity exercise. This acts to impair airflow and cause shortness of breath , stridor and often discomfort in the throat and upper chest.
