Exercised Induced Asthma
Exercise induced asthma is a reversible airway obstruction that is a direct result of the ventilatory response to exercise. It thought to occur as a consequence of fluid loss in the airways as inspired air is conditioned during exercise. The deconditioned air is thought to trigger an immune or allergic response which may manifest in bronchospasm. Exercise induced asthma is characterized by coughing, wheezing, mucus production and general shortness of breath. EIA attack can usually occur within 10 minutes after exercise but can occur at any time during exercise.
