Asthma

Asthma is a condition in which your airways narrow and swell and produce extra mucus. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Asthma can't be cured, but its symptoms can be controlled.
 

Symptoms:

• Shortness of breath

• Chest tightness or pain

• Trouble sleeping caused by shortness of breath, coughing or wheezing

• Severe asthma attacks can be life threatening.
