Asthma is a chronic respiratory condition that affects the airways, the tubes that carry air in and out of the lungs. It is characterised by inflammation and narrowing of the airways, which can cause recurring episodes of wheezing, coughing, chest tightness, and shortness of breath.
In a person with asthma, the airways are overly sensitive to specific triggers, such as allergens (e.g., pollen, pet dander), irritants (e.g., smoke, strong odours), respiratory infections, exercise, or weather changes. When exposed to these triggers, the airways become inflamed and constrict, leading to asthma symptoms.
Asthma symptoms can vary from person to person and can also differ in intensity and frequency. Some people may experience mild, occasional symptoms, while others may have more frequent and severe episodes. In extreme cases, asthma attacks can be life-threatening and require immediate medical attention. The most common symptoms of asthma include:
Wheezing
A whistling or high-pitched sound when breathing out, often audible to others. Wheezing may also occur during breathing in some cases.
Shortness of breath
A feeling of breathlessness or difficulty breathing may be accompanied by a sensation of tightness in the chest.
Coughing
A persistent or recurring cough, particularly at night or early morning. The cough may be dry or produce phlegm.
Chest tightness
A discomfort or pressure in the chest is often described as a squeezing sensation.
Rapid breathing
Increased breathing rate due to the effort required to breathe correctly.
Asthma symptoms can be triggered or worsened by various factors, including exposure to allergens (such as dust mites, pollen, and pet dander), irritants (such as smoke, strong odours, and pollution), respiratory infections, exercise, cold air, emotional stress, and certain medications. Some individuals may experience symptoms only during specific situations or seasons, while others may have ongoing symptoms.
It is important to note that not all wheezing or coughing is caused by asthma, and these symptoms alone do not necessarily indicate asthma. Proper diagnosis by a healthcare professional is crucial for determining whether asthma is the underlying cause of these symptoms.
How Many People Have Asthma in Australia?
We can provide you with the statistics available as of September 2021. However, please note that the current numbers may have changed, and it’s always best to refer to the latest data from reliable sources like government health agencies or research organisations.
According to the Australian Bureau of Statistics (ABS) National Health Survey 2017-2018, an estimated 2.7 million Australians (11.2% of the population) reported having asthma. This includes both adults and children. Asthma prevalence tends to be higher in children, with approximately 10.2% of children aged 0-14 years reporting asthma compared to 11.5% of adults.
It’s worth mentioning that asthma prevalence can vary across different regions and age groups, and it may also change over time due to various factors such as changes in population demographics, environmental conditions, and healthcare practices.
For the most up-to-date and accurate information on asthma prevalence in Australia, I recommend consulting recent reports or studies from reputable sources like the Australian Institute of Health and Welfare (AIHW) or the Australian Department of Health.
How is Asthma Treated?
Asthma is a chronic condition with no cure, but it can be effectively managed with appropriate treatment. Asthma treatment aims to achieve and maintain reasonable asthma control, which involves minimising symptoms, preventing asthma attacks, and maintaining normal lung function. The treatment approach may vary depending on the severity of asthma and individual patient needs. Here are some standard treatment options for asthma:
Medications
Quick-relief medications (Bronchodilators)
These short-acting medications, such as short-acting beta-agonists (SABAs), provide immediate relief during asthma symptoms or an asthma attack. They work by relaxing the muscles around the airways, allowing them to open up and ease breathing.
Long-term control medications
These medications are taken regularly to control asthma and prevent symptoms. They include inhaled corticosteroids, long-acting beta-agonists (LABAs), leukotriene modifiers, mast cell stabilisers, and combination inhalers that contain both a corticosteroid and a long-acting beta-agonist.
Biologic therapies
In some cases, when asthma is severe and not well-controlled with other medications, biologic therapies may be prescribed. These medications target specific immune system molecules involved in asthma, helping to reduce inflammation and prevent asthma symptoms.
Asthma Action Plan
Individuals with asthma must work with their healthcare provider to develop an asthma action plan. This plan outlines the daily management of asthma, including medication use, recognising and managing symptoms, and steps to take in case of worsening symptoms or an asthma attack.
Trigger Avoidance
Identifying and avoiding triggers that can worsen asthma symptoms is essential to managing the condition. Common triggers include allergens (e.g., pollen, dust mites), irritants (e.g., smoke, strong odours), cold air, exercise, and respiratory infections. Taking measures to reduce exposure to triggers can help prevent asthma symptoms.
Regular Monitoring
Regular check-ups with a healthcare provider are crucial for monitoring asthma control and adjusting treatment. This may involve measuring lung function with a spirometer, tracking symptoms, and assessing medication effectiveness.
Education and Self-Management
Education plays a vital role in asthma management. Patients and their families should learn about asthma, its triggers, proper medication techniques, and how to recognise and respond to worsening symptoms or asthma attacks. Self-management skills empower individuals to take an active role in controlling their asthma and seeking timely medical help when needed.
Individuals with asthma must consult with their healthcare provider to develop a personalised treatment plan based on their asthma’s severity, symptoms, and other factors. The treatment plan may be adjusted over time to ensure optimal asthma control.
