When something keeps the air from moving in and out of the airways in your lungs, it's called
an airway obstruction. When someone has asthma,
the airways may become obstructed, or blocked, because the airways are swollen, narrow,
and clogged with thick mucus. Obstructed airways can cause coughing, wheezing, and
shortness of breath.
