Asthma

Asthma, a chronic lung disease, can affect people of all ages. Asthma causes the lung’s airways to become reactive to “triggers” and swell. Reactions to triggers can vary from a mild cough to extreme difficulty breathing. If you think you or your family member may have asthma, notice the signs and triggers. Discuss with your provider and learn how to manage symptoms.

What Are the Signs and Triggers for Asthma?

Asthma signs:

  • Coughing: Persistent coughing can sometimes be the only symptom of asthma. Coughing with mucus or phlegm. Coughing is worse at night or early morning.
  • Wheezing: A whistling or squeaky sound when you breathe.
