What is Asthma

Asthma is a chronic condition that affects people of all ages and approximately 2.8 million Australians, including around 8% of children under 14 years.

Asthma causes inflammation and narrowing of the airways, leading to symptoms such as:

Wheezing
Coughing
Chest tightness
Shortness of breath

These symptoms can vary between individuals and may occur at different times, including:

At night or early in the morning
During or after physical activity
In response to specific triggers like allergens, smoke, or cold air

While there is no cure for asthma, with early diagnosis, and a personalised asthma management plan can help adults and children live their best life with confidence.

Asthma diagnosis and management

Only 32% of individuals with asthma have a written asthma action plan.

A proper diagnosis is important so you can manage asthma safely. Lung function testing is the most reliable way to confirm asthma and understand how severe it is.

Once diagnosed, your doctor can help you create a personal asthma action plan. This plan explains how to manage your asthma every day and what to do if your symptoms get worse.

Why management matters

Only about 1 in 3 people with asthma have a written action plan, which means many people may not be managing their condition as well as they could.

Without proper management, asthma can flare up, sometimes suddenly — this is called an asthma attack. Following your plan and seeing your healthcare team regularly can help you breathe easier and stay healthy.

If you’re experiencing symptoms or haven’t been tested, talk to your GP or book a free lung function test at one of our Respiratory Hubs.

What triggers asthma

Asthma triggers can be different for everyone.

Taking your preventer daily as prescribed helps airways handle triggers. Identifying and avoiding triggers where possible also improves asthma control.

Exercise or physical activity.
Colds and flu.
Allergens such as animals, house dust mites, moulds and pollens.
Poor air quality including smoke, dusty environments, traffic, cleaning products and scents.
Weather and sudden changes in temperature.
Certain medications.
Emotions such as stress and anxiety.
Food and additives.
Medical conditions such as obesity, hormonal changes and gastro-oesophageal reflux disease.
