– [Narrator] Seven million
children in the United States have asthma. Asthma is caused by
inflammation in the airways inside the lungs, also known
as the bronchi and bronchioles. Quite often, airborne allergens
like dust mites, pollen, mold, and animal dander
will cause inflammation. This causes the muscles
around the airways to react by tightening. Thereby constricting the airway. Additionally, airway walls begin to swell, and cells begin to produce
more mucus than usual, which further restricts
airflow in the lungs. You’ll feel a tightening of
the chest, shortness of breath, and wheezing. To combat these symptoms,
quick relief medication is often inhaled directly into the lungs which causes the muscles to relax opens the airways for oxygen to pass. Quick relief medications are often only a short-term solution. Your doctor can work with you to develop a long-term
asthma control plan.
