  • Asthma can be caused by allergies, respiratory infections, weather changes and poor air quality. Signs of an asthma attack include coughing, wheezing and shortness of breath.
  • Allergies are most commonly triggered by pollen and pet dander. Symptoms include watery eyes, runny nose, swollen throat, skin rashes and, in some cases, asthma attacks.
