What
is Asthma?
Asthma is a
chronic lung condition with symptoms of difficulty breathing
and wheezing caused by inflammation and narrowing of the air passages. The
condition ranges
from mild to severe. During an asthma attack, the airways become
inflamed and narrower
as the muscles surrounding them constrict. The flow of air is
blocked partially or completely as mucus produced by the inflammation
fills a narrower passageway. Asthma affects both the lung's larger airways,
called
the bronchi, and the lung's smaller airways, called
the bronchioles. Treatment focuses on preventing or stopping
inflammation, and relaxing muscles that line the airways.
