Understanding Asthma: Symptoms, Triggers and Treatment Options

Asthma is a common condition that affectsthe airways (breathing tubes) in the lungs. It can cause symptoms such as wheezing,shortness of breath, and chest tightness—but with the right treatment, mostpeople can live very well with asthma.

What is Asthma?

Asthma is a condition where the airways become:

·        Inflamed (swollen)

·        Narrowed

·        Sensitive to triggers

This makes it harder for air to move in andout of the lungs, especially during flare-ups.

Asthma can vary from mild and occasional symptoms to more persistent or severe disease.

Common Symptoms of Asthma

Asthma symptoms can come and go. You might notice:

·        Shortness of breath

·        Wheezing (a whistling sound when breathing)

·        Chest tightness

·        A persistent cough (especially at night or early morning)

Some people only experience symptoms during exercise or when they are unwell.

What Triggers Asthma?

Asthma symptoms are often triggered by certain factors, including:

·        Colds and viral infections

·        Allergens (dust mites, pollen,pet dander)

·        Exercise

·        Cold air

·        Smoke or air pollution

·        Strong smells or chemicals

Everyone’s triggers are different, and identifying yours is an important part of managing asthma.

How is Asthma Diagnosed?

Your doctor may recommend:

·        Spirometry (lung function test): Measures how well your lungs are working

·        Trial of inhaler therapy: To see how your symptoms respond

·        Additional tests: Sometimes blood tests or FeNO (a breath test) to assess inflammation

Asthma Treatment Options

The goal of asthma treatment is to:
✔ Reduce symptoms
✔ Prevent flare-ups
✔ Keep you active and well

1. Inhalers (Daily Control + Quick Relief)

These are the most important medications for many people with asthma.

They:

·        Reduce airway inflammation

·        Prevent symptoms from developing

Adults with asthma are usually given a combination inhaler that includes 2 medications – one that provides quick relief and another that reduces airway inflammation. Both medications are important in order to achieve good control of symptoms and prevent flare-ups.

Inhalers come in many different shapes and sizes, and optimum inhaler technique varies. If you are unsure about how to use your inhaler effectively, please speak to your pharmacist or doctor. There are also educational videos available on the Asthma Australia website at https://asthma.org.au/devices-techniques/

If you are having difficulty using your prescribed inhaler, switching to different type of device may be an option. Please speak to your doctor if this is the case.

2. Asthma Action Plan

An asthma action plan is a written document that tells you:

·        How often to take your inhaler and in what dose

·        What to do if your symptoms increase

·        What to do in an emergency

Written action plans are essential for people living with asthma, as they give you the right information to treat your asthma effectively, and to know when to seek help.

3. Advanced Treatments (Specialist Care)

For people with more severe asthma, additional options may include:

·        Biologic injections

·        Specialised tablets

·        Personalised treatment plans

These are usually managed by a respiratory specialist.

Why Good Asthma Control Matters

When asthma is well controlled, you should:

·        Have minimal or no symptoms

·        Sleep well at night

·        Stay active and exercise

·        Rarely need your reliever inhaler

Poorly controlled asthma can increase the risk of flare-ups and hospital visits, so it’s important to review your treatment regularly.

Simple Tips to Manage Asthma

·        Take your preventer inhaler as prescribed

·        Check your inhaler technique with your doctor or pharmacist

·        Avoid known triggers where possible

·        Have an asthma action plan

·        Stay up to date with vaccinations

When Should You Seek Help?

You should speak to your GP or specialistif:

·        Your symptoms are worsening

·        You are using your reliever inhaler more often

·        You are unsure how to use your inhaler or are having difficulty with using it effectively

·        You have frequent flare-ups

·        You are unsure if your asthma is well controlled

Asthma is very common, and effective treatments are available. With the right plan in place, most people can manage their asthma and live a full, active life.
