What is Asthma?
Posted by: imers : Category: Asthma
One in ten children and one in three adults suffer from chronic asthma. That is about 15 million Americans alone. An acute asthma attack is caused by inflammation in the airways of the lungs, causing contraction and narrowing of the airways (bronchi oles), restricting airflow and making breathing very difficult.
Chronic asthma is a lung condition characterized by frequent asthma attacks and requiring medical management to prevent and minimize acute attacks.
