The most common asthma symptoms are:

- shortness of breath
- wheeze
- chest tightness, and/or
- a dry, irritating and continual cough (especially at night/early in the morning, or with exercise or activity)

These symptoms are caused by the narrowing of the airway. Symptoms vary from person to person, and may also change over time. If your asthma is well controlled you should only have occasional asthma symptoms.

If you have asthma, your doctor will prescribe medication to help control your asthma. The type and amount you need to take will depend on your symptoms, and how often you have them.

It’s important to monitor your asthma by being aware and acknowledging if your symptoms are getting worse.

Some people will also regularly measure their peak flow. Your written Asthma Action Plan prepared in partnership with your doctor, is a helpful reference for you to know how to respond if your asthma is getting worse.
