Understanding Asthma - VHL HealthSheet #82427_VA
Asthma is a disease that inflames and narrows the airways in your lungs. If the airways become so narrow that you have trouble breathing, it’s called an asthma flare-up (or “asthma attack”). Air travels into and out of the lungs through tubes called airways.
