(HealthDayNews) -- During an asthmatic episode, the inside walls of your airways become inflamed, making them oversensitive to particles you are allergic to or find irritating, according to the U.S. National Heart, Lung, and Blood Institute.
When the airways react this way, they narrow, allowing less air to flow to your lungs. This causes symptoms such as wheezing, coughing, chest tightness and trouble breathing.
While asthma cannot be completely cured, most patients can control it so that they have only minimal and infrequent symptoms. This means staying away from things that trigger attacks and using inhalers or other asthma medicines as directed by your doctor.
