What is Asthma?
There are an estimated 17 million people in the U.S. with self-reported asthma. Asthma is a chronic disease marked by wheezing, chest tightness, and/or shortness of breath. Consult a physician if you or someone you know has the following symptoms:
- Coughing a lot during or after exercise
- Shortness of breath
- Wheezing while breathing
- Tight feeling in the chest
Asthma symptoms are caused by the constriction (tightening of the muscles) and the inflammation (swelling and irritation) of the airways. Constriction and inflammation of the airways and increased mucosa make it difficult and sometimes impossible to breathe.
