What is Asthma?

What is asthma? Asthma is a disease that affects more than 20 million Americans and 1/3 of those cases are in children. In addition, more than 4,000 people die due to complications from their asthma. Attacks can range from mild to life threatening. During an asthma attack, the small tubes that carry air through the lungs react to the asthma trigger and begin to swell. This tightens the airway and allows less air to flow through. At the same time, the muscles that surround the tubes also constrict and close the tubes even further. This results in difficulty breathing and pain or tightness in the chest. In this video, Dr. Preeti Parikh further explains what exactly happens and what causes an asthma attack.
