What is COPD?

Chronic Obstructive Pulmonary Disease

COPD is a chronic lung disease caused by damage to the airways or lungs. This damage leads to blocked airflow, making it progressively harder to breathe. It includes two main conditions — emphysema and chronic bronchitis — and is a leading cause of disability worldwide.

Common Symptoms

Recognising the signs of COPD

COPD symptoms tend to develop slowly and worsen over time. Many people mistake early symptoms for normal ageing or a recurring cough. Knowing the warning signs early can lead to faster diagnosis and better management.

Symptoms

Persistent cough, sometimes with mucus or phlegm
Shortness of breath, especially during physical activity
Wheezing and chest tightness
Frequent fatigue and low energy
Symptoms worsen progressively over time

Causes & Risk Factors

What leads to COPD

COPD is caused by long-term exposure to irritants that damage the lungs and airways. Smoking is the most common cause, but it is not the only one — environmental and genetic factors also play a significant role.

Risk Factors

Cigarette smoking — the leading cause in high-income countries
Long-term exposure to air pollution, dust, or chemical fumes
A rare genetic condition called alpha-1 antitrypsin deficiency
Around one in four people with COPD have never smoked

How Your Lungs Work

Understanding lung function and how COPD changes it

Understanding how the human lungs work can give much greater clarity as to how COPD makes breathing and physical activity challenging.

How a Healthy Lung Works

The Pathway — Air enters through the nose or mouth, travels down the windpipe, and enters the lungs through two large tubes called bronchi.
The Bronchioles — These tubes branch into thousands of smaller, thinner tubes called bronchioles that carry air to the alveoli.
Gas Exchange — The alveoli insert oxygen into the blood and remove carbon dioxide from it.
Elasticity — Healthy lungs are elastic and inflate like a balloon when you breathe in, then deflate when you breathe out. With COPD, the lungs become much less springy, which traps air inside.

Stages of COPD

GOLD grading system & Australian COPD-X Guidelines

COPD is classified into four grades of severity based on spirometry testing — specifically the forced expiratory volume in one second (FEV₁) — alongside symptom burden and history of flare-ups. Diagnosis requires a post-bronchodilator FEV₁/FVC ratio of less than 0.7.

GOLD Grades

Grade 1 Mild FEV₁ ≥ 80%

Airflow is only mildly limited
Mild cough or slight increase in mucus may be present or absent
Many people at this stage are unaware they have COPD
Management: smoking cessation, vaccinations (flu, pneumococcal, RSV), short-acting bronchodilators as needed

Grade 2 Moderate FEV₁ 50–79%

Breathlessness, coughing, and wheezing become more noticeable during physical activity
This is the stage at which most people first seek medical attention
Long-acting bronchodilators (LABA and/or LAMA) recommended as initial therapy
Pulmonary rehabilitation referral should be considered

Grade 3 Severe FEV₁ 30–49%

Significant breathlessness during routine daily activities and sometimes at rest
Chronic fatigue, reduced exercise tolerance, and frequent exacerbations
Combination inhaler therapy (LABA + LAMA) is standard; inhaled corticosteroids may be added
Pulmonary rehabilitation is strongly recommended

Grade 4 Very Severe FEV₁ < 30%

Severely impaired lung function affecting all aspects of daily life
Breathing difficulties at rest; blood oxygen levels may be critically low
Daily oxygen therapy, advanced medications, and specialist care are typically required
Advanced care planning and consideration of palliative support is appropriate

Important Note

Grading alone does not determine treatment. Clinicians also assess symptom severity and exacerbation history to guide individualised management. COPD affects every person differently — two people at the same grade can have very different experiences and outcomes.

Medications Explained

How COPD medications and therapies work

Medications for COPD are usually designed to open the airways or reduce inflammation and swelling. They work alongside lifestyle changes to manage symptoms and slow progression.

Common Medications

Bronchodilators — The primary medications for COPD, usually taken via inhaler. They relax the muscles around the airways, making breathing easier.
Inhaled corticosteroids — Reduce inflammation in the airways and are typically added for patients with frequent exacerbations.
Combination inhalers (LABA + LAMA) — Standard for moderate-to-severe COPD; combine two types of bronchodilator for greater effect.

Breathing Techniques

Pursed-lip breathing — Slows breathing and keeps airways open longer, reducing air trapping.
Diaphragmatic breathing — Strengthens the diaphragm and improves breathing efficiency through structured exercises.

Exercise & Pulmonary Rehabilitation

Evidence-based information for people living with COPD

Exercise and pulmonary rehabilitation (PR) are among the most effective treatments for COPD, reducing symptoms and improving quality of life beyond what medication alone can achieve.

What is Pulmonary Rehabilitation?

Structured program combining exercise training and education
Improves fitness, reduces breathlessness, and supports self-management
Available in hospitals, community settings, at home, or via telehealth
Australian programs typically run 8 weeks with two supervised sessions weekly

Benefits

Cuts hospital readmissions by ~50% after a flare-up
Improves walking distance by 50–60 metres
Reduces breathlessness, anxiety, and depression
Slows physical decline and maintains independence
Telerehabilitation has higher completion rates (93%) than in-person (70%)

Types of Exercise

Aerobic — walking, cycling, treadmill
Resistance training — addresses muscle weakness
Breathing exercises — pursed-lip and diaphragmatic techniques
Balance and flexibility — reduces fall risk
HIIT — where appropriate and supervised

When to Start & Access in Australia

Recommended for anyone whose breathlessness limits daily activities
Within four weeks of hospital discharge after a flare-up
Home-based programs deliver equivalent outcomes to hospital-based ones
Find a program: lungfoundation.com.au
Ask your GP or respiratory specialist for a referral

Nutrition & Diet

How diet and exercise support COPD management

Nutrition and regular physical activity are important components of COPD management. A healthy diet can strengthen respiratory muscles, support a healthy body weight, and reduce breathlessness.

Key Principles

Good nutrition helps strengthen the muscles used for breathing
Being underweight or overweight both worsen breathlessness — maintaining a healthy weight matters
Smaller, more frequent meals can reduce the effort of eating and limit breathlessness after meals
Aim for 30 minutes of exercise 5 times per week to develop a routine and manage breathlessness
Staying hydrated helps keep mucus thin and easier to clear

Sleep & Breathing in COPD

How COPD affects sleep, and what can help

Poor sleep is one of the most common and under-recognised challenges for people living with COPD. Up to 78% of people with COPD experience nocturnal sleep disturbance, with prevalence rising as airflow limitation worsens.

Why COPD Affects Sleep

Breathing slows during sleep, causing oxygen to drop and CO₂ to build up — especially in REM sleep
Cough, mucus, wheezing, and chest tightness interrupt sleep
Lying flat worsens breathlessness
Anxiety about breathing makes it hard to fall asleep
Some COPD medications can be mildly stimulating if taken near bedtime

Common Sleep Problems

Insomnia — difficulty falling or staying asleep, or waking early
Nocturnal hypoxemia — oxygen drops during sleep, even with adequate daytime levels
Overlap syndrome — COPD combined with obstructive sleep apnoea (OSA)
Restless legs syndrome — linked to oxygen and CO₂ imbalance
Morning headaches — a sign of overnight CO₂ build-up

What is Overlap Syndrome?

Co-existence of COPD and OSA, causing more severe oxygen drops and worse outcomes
Associated with increased cardiovascular disease, pulmonary hypertension, and hospitalisation
Each condition worsens the other through inflammation and impaired immune function

Tips for Better Sleep

Sleep on your side or elevated 30–45° to ease breathlessness
Practice pursed-lip or diaphragmatic breathing before bed
Avoid caffeine, heavy meals, alcohol, and smoking before bed
Keep your bedroom cool (~18°C), quiet, and dark
Limit naps to under 30 minutes; avoid late-afternoon napping
Stick to consistent sleep and wake times daily
See your doctor if you suspect sleep apnoea — a sleep study may be needed

Medical Treatments

CPAP — first-line for overlap syndrome; improves oxygen and sleep quality
BiPAP — used when CO₂ is elevated or CPAP alone is insufficient
Supplemental nocturnal oxygen — for severely low daytime oxygen; improves survival with consistent use
CBT-I — preferred treatment for insomnia; sleeping pills are generally avoided as they suppress breathing

Quitting Smoking

The single most effective COPD intervention

COPD is strongly linked to smoking. Quitting is the most impactful step a person with COPD can take — it slows disease progression significantly and can improve lung function over time.

Why Quitting Matters

Smoking causes the lungs to fill with tar, reducing elasticity and making breathing progressively harder
Continuing to smoke accelerates lung damage and worsens all COPD symptoms
Quitting at any stage of COPD slows further decline and reduces exacerbation risk
Even long-term smokers benefit — it is never too late to quit

Support Available

Speak to your GP about nicotine replacement therapy (patches, gum, lozenges) or prescription medications
