What is Asthma?

Asthma is a chronic or long-term disease of the airways, the tubes that carry air into our lungs. It causes inflammation and narrowing of the bronchial tubes that leads to airflow limitation. 

Asthma has many symptoms and children with asthma may experience some or all of them.

Does my child have asthma?

What does asthma look like?

Talk to your doctor about asthma if you notice your child experiencing any of the following:

Cough

in the middle of the night that often wakes you or your child up

Cold symptoms

congestion, cough, trouble breathing that won't go away after a few weeks

Wheezing

coughing, trouble breathing or chest tightness after a few minutes of exercise, or during specific times of year such as “allergy season” or cold seasons


How Asthma Affects Your Lungs

Asthma makes breathing difficult and often results in coughing, wheezing, shortness of breath and tightness in the chest.  

Here's what happens to your body if you have asthma:

  • Inhaled triggers cause the lungs to over-react
  • The airways in the lungs get inflamed and swollen
  • Mucus is produced and builds up in the airways
  • Swelling and mucus may block and narrow the airways
  • Sometimes the muscles around the airways tighten and squeeze the airways
Lungs

Asthma may be more likely when children have:

family with asthma

  • or allergic conditions, such as eczema, hay fever, and even food allergies

exposure to triggers

  • at home such as cigarette smoke, animal or dust allergies

allergies or eczema

  • can make asthma symptoms worse and cause asthma to be uncontrolled
