The airway narrowing or obstruction and "twitchiness" cause the asthma symptoms to come in "waves" called flares or attacks. The "twitchy" lungs overreact even to cold air, exercise and smoke. This narrowing is called inflammation.Īirways become super-sensitive or hyper-reactive to things that do not bother people with normal lungs. Extra mucus and swelling of the airway linings, which all add to the narrowing.There is tightening of the muscles surrounding the airways (called bronchospasm or bronchoconstriction).These triggers cause the airway tubes to become narrow, making it hard to move air in and out of the lungs. Some examples of triggers include: upper respiratory viral infections, allergies, irritants, weather changes and exercise (details below). About 5 million American children are estimated to have asthma.įactors leading to increase in symptoms are called triggers. 1 reason that children miss school, go to emergency rooms, and are admitted to hospitals. The frequency and intensity of symptoms tend to vary over time.Īsthma is the most common chronic disease of childhood and the No.
