How Asthma Can be Deadly

WRITTEN BY: Xuan Pham

About one in 12 Americans, or 25 million people, are diagnosed with asthma. Asthma is a chronic respiratory condition marked difficulty breathing, coughing, wheezing, and shortness of breath. These symptoms are brought on by the airway swelling up and producing extra mucus in response to different types of allergens.

Patients diagnosed with asthma take long-term medications like inhaled corticosteroids, and may also have to carry fast-acting rescue medications in case of a serious asthma attack. The condition has no cure, but treatments can significantly help improve the quality of life for sufferers.Watch the video to learn more about asthma and it symptoms.
