What Is Asthma?

Asthma is a chronic disease-one that cannot be cured. When you have asthma, the airways in your lungs are very sensitive and can become inflamed and swollen.  In addition, certain triggers can cause airway muscles to squeeze; this is called bronchoconstriction.  The airway also can produce excess mucus.


Symptoms of asthma episodes

-Chest tightness


-Shortness of breath
