What is Asthma?
Asthma is a chronic inflammatory lung disease that affects the airways in your lung. During an acute asthma episode, the airway linings are swollen and inflamed. The airways also produce more mucus and the muscles around the airways tighten. All of this leads to narrower airways, which makes it harder to breathe.
Asthma may be triggered by allergies, colds, sinusitis, exercise, strong emotions (laughing/crying), smoke or pollution, and weather changes.
Asthma affects more than 24 million people in the U.S., including more than 6 million children (Source: NIH). It is one of the most common chronic diseases of childhood. While many people think asthma only comes on during childhood or that it “goes away”, it can occur throughout your life. It may also abate only to reoccur in middle age, for example.
