Exercise-induced asthma

Exercise-induced asthma

Exercise-induced asthma, also known as exercise-induced bronchoconstriction (EIB), is a condition in which vigorous physical activity triggers acute airway narrowing in individuals. This condition is not exclusive to athletes and can affect anyone participating in physical activities.

Pronunciation

Exercise-induced asthma: /ˈɛksəˌsaɪz ɪnˈdaɪst ˈæzmə/

Etymology

The term "exercise-induced asthma" is derived from the English words "exercise" (from Latin 'exercitus', past participle of 'exercere' meaning 'to keep busy or to work'), "induced" (from Latin 'inducere' meaning 'to lead in'), and "asthma" (from the Greek 'asthma', meaning 'panting or short-drawn breath').

Definition

Exercise-induced asthma is a type of asthma that is triggered by physical activity or exercise. Symptoms may include coughing, wheezing, shortness of breath, chest tightness, and fatigue during exercise. The symptoms often start soon after beginning exercise and can be worse when exercising in cold, dry air.

Related Terms

• Asthma: A chronic condition that affects the airways, causing them to become inflamed and narrow, leading to breathing difficulties.
• Bronchoconstriction: The constriction or narrowing of the bronchi in the lungs due to the tightening of surrounding smooth muscle.
• Bronchodilator: A medication that relaxes and opens the airways, or bronchi, in the lungs.
• Inhaler: A device that delivers medication directly to the lungs to relieve asthma symptoms.
• Spirometry: A common office test used to diagnose and monitor lung diseases by measuring lung function, specifically the amount and speed of air that can be inhaled and exhaled.

Treatment

Treatment for exercise-induced asthma includes the use of bronchodilators or inhalers before exercise to prevent the airways from narrowing. Regular exercise can also help improve lung function over time.

Prevention

Prevention strategies for exercise-induced asthma include warming up before exercise, wearing a mask or scarf over the mouth in cold weather, and avoiding exercise during high pollen counts or when air pollution levels are high.
