What is exercise-induced bronchoconstriction (EIB)?

Exercise-induced bronchoconstriction (EIB) refers to a condition where the airways temporarily narrow in response to physical activity. This phenomenon typically occurs during or immediately following exercise and can result in symptoms such as wheezing, coughing, shortness of breath, and chest tightness. EIB is particularly prevalent in individuals with asthma, but it can also affect those without a diagnosed respiratory condition.

The key aspect of EIB is its temporary nature; the bronchoconstriction subsides once the individual stops exercising or takes measures to relieve the symptoms, such as using bronchodilators. This distinguishes EIB from more chronic conditions, where airway narrowing is a permanent feature. Understanding that EIB is triggered by physical exertion helps in its management and prompts individuals to be proactive in undertaking preventive measures, particularly before engaging in vigorous activities.
