Key facts
COPD at a glance.
The essentials, in plain English — what it is, what causes it, how it is diagnosed and staged, and why exacerbations matter.
-
What it is
A progressive lung condition with irreversible airflow obstruction — chronic bronchitis, emphysema, or both.
-
Biggest cause
Smoking — cumulative pack-years drive most UK cases. Occupational dust and biomass smoke also contribute.
-
Genetic form
Around 1% of cases are linked to alpha-1-antitrypsin deficiency — worth testing when the story doesn’t fit.
-
Diagnosis
Spirometry is diagnostic — a post-bronchodilator FEV1/FVC ratio below 0.7 confirms fixed obstruction.
-
Severity staging
GOLD 1–4 grades severity by FEV1, combined with symptoms and exacerbation risk for the ABE assessment.
-
Why exacerbations matter
Each flare-up accelerates decline — prevention through inhalers, vaccines and rehab changes the trajectory.
Why this guide matters
Modern COPD care has moved on.
Spirometry, tailored inhaler therapy and pulmonary rehab have transformed what good COPD care looks like. The three points below shape everything else on this page.
-
Spirometry makes the diagnosis
No spirometry means no confirmed diagnosis. A post-bronchodilator FEV1/FVC below 0.7 is the standard.
-
Stopping smoking changes the curve
It is the single intervention that slows disease progression — and it is never too late to benefit.
-
Rehab beats most medications
Pulmonary rehabilitation improves breathlessness and quality of life more than adding another inhaler.
How the diagnosis is made
From first symptoms to a clear plan.
The steps a UK GP or respiratory team will normally follow, in order — so you know what to expect and why.
Phase 1 · Recognising
Symptom pattern and spirometry
Phase 2 · Confirming
Full PFTs, imaging and genetic testing
Phase 3 · Managing
Cardiac overlap and self-management plan
- 01
Recognising
Symptom + smoking history
Progressive breathlessness, chronic cough or sputum in an adult with a smoking history — the starting point for suspecting COPD.
- 02
Recognising
Spirometry (post-bronchodilator)
The diagnostic test — FEV1/FVC ratio below 0.7 after a bronchodilator confirms fixed airway obstruction.
- 03
Confirming
Full PFTs and DLCO
Lung volumes and gas transfer clarify severity, distinguish emphysema from chronic bronchitis and pick up overlap.
- 04
Confirming
Chest X-ray or CT if uncertain
Used to exclude alternative diagnoses — lung cancer, bronchiectasis, interstitial disease — when the picture is atypical.
- 05
Confirming
Alpha-1-antitrypsin blood test
Recommended in younger patients, non-smokers, or those with a family history — around 1% of COPD is genetic.
- 06
Managing
Cardiology work-up (overlap)
Breathlessness in ex-smokers often has a cardiac component — ECG, BNP or echo when heart disease is suspected.
- 07
Managing
Structured self-management plan
A written plan for daily inhalers, rescue packs, when to seek help and how to prevent the next exacerbation.
Typical timeline: 4–8 weeks from first spirometry to a settled inhaler regimen.
Symptoms
What COPD actually feels like.
Symptoms creep in slowly and are easy to normalise. Here is what to look for and when to act.
-
Progressive breathlessness
Slowly worsening breathlessness on exertion — often first noticed on stairs or inclines.
-
Chronic cough
A persistent cough — often the first symptom, sometimes dismissed as a “smoker’s cough”.
-
Sputum production
Regular clear or white sputum, especially first thing in the morning — a hallmark of chronic bronchitis.
-
Exacerbations
Episodes of worse breathlessness, coughing and coloured sputum — often needing steroids or antibiotics.
-
Morning symptoms worst
Symptoms cluster on waking — chest tightness, sputum and breathlessness ease as the day progresses.
-
Weight loss (advanced)
Unintentional weight and muscle loss in severe disease — a marker of poor prognosis worth addressing.
-
Ankle oedema
Swollen ankles can signal cor pulmonale — right heart strain from long-standing lung disease.
-
Red flag
Acute severe breathlessness with cyanosis (blue lips or fingertips) — call 999.
Treatment
How COPD is treated in the UK.
Smoking cessation first, then tailored inhaler therapy, rehab and — when needed — oxygen or surgical options.
-
Smoking cessation
The single biggest intervention — the only thing proven to slow COPD progression. NHS Stop Smoking services help.
-
Short-acting bronchodilator
SABA (salbutamol) or SAMA (ipratropium) as a reliever for occasional symptoms and mild disease.
-
LAMA (tiotropium)
A long-acting muscarinic antagonist — first-line maintenance inhaler for most people with persistent symptoms.
-
LABA + LAMA combination
Dual bronchodilation in a single inhaler — better symptom control than either component alone.
-
LABA/LAMA/ICS triple therapy
Adding an inhaled steroid for frequent exacerbators or those with an asthmatic overlap phenotype.
-
Pulmonary rehabilitation
A structured exercise and education programme — improves breathlessness, exercise tolerance and quality of life.
-
Home oxygen
Long-term oxygen therapy for patients meeting strict criteria (persistent hypoxaemia) — improves survival.
-
Lung volume reduction / transplant
Specialist options for selected severe emphysema — endobronchial valves, surgery, or transplant referral.

Red flags
When COPD becomes an emergency.
Most COPD is managed well in the community. These are the situations where you should act today.
-
Acute severe exacerbation
Sudden marked breathlessness, unable to complete sentences — needs urgent assessment or 999.
-
Cyanosis
Blue lips or fingertips — a sign of dangerously low oxygen. Call 999.
-
Reduced consciousness
Drowsiness or confusion during an exacerbation can signal CO₂ retention — 999.
-
Cor pulmonale
Progressive ankle swelling and raised neck veins — right heart failure needing review.
-
Massive haemoptysis
Coughing large volumes of blood — a medical emergency, call 999.
-
Sudden pneumothorax
Abrupt sharp chest pain and breathlessness — bullae in emphysema can rupture. Urgent assessment.
-
Rapid weight loss
Unintentional weight loss can reflect advanced disease or coexisting lung cancer — investigate promptly.
-
New arrhythmia
Palpitations or an irregular pulse — atrial fibrillation is common in COPD and needs review.
-
End-of-life planning
Advanced COPD deserves honest conversations about ceilings of care, advance directives and palliative support.
Living with it
A long-term condition, but a very manageable one.
Four things that make the biggest difference day to day — technique, a rescue plan, vaccination and pulmonary rehab.
A quiet reminder
Every exacerbation avoided is a step preserved.
Prevention through inhalers, vaccination and rehab genuinely changes long-term outcomes — it is worth the effort.
- 01 Technique
Get the inhaler right
Poor technique is the single biggest reason inhalers fail. Ask your pharmacist or nurse to check yours.
- 02 Rescue pack
Have a plan for flare-ups
A written self-management plan plus a rescue pack of steroids and antibiotics shortens exacerbations.
- 03 Vaccines
Flu, COVID and pneumococcal jabs
All three cut the risk of the infections that trigger most exacerbations — free on the NHS with COPD.
- 04 Rehab
Pulmonary rehab changes lives
A structured 6–8 week programme improves breathlessness and stamina more than any single medication.
Frequently asked
Everything we get asked about COPD.
Quick answers on spirometry, GOLD staging, triple therapy, rehab and when to worry.
-
What is COPD?
Chronic obstructive pulmonary disease — a long-term lung condition where the airways are permanently narrowed. It usually combines chronic bronchitis (inflamed airways with sputum) and emphysema (damaged alveoli).
-
How is COPD diagnosed?
Spirometry — a breathing test. A post-bronchodilator FEV1/FVC ratio below 0.7 confirms fixed airflow obstruction. Symptom pattern, smoking history and imaging support the diagnosis.
-
What are the GOLD stages?
GOLD grades severity 1–4 by FEV1 as a percentage of predicted — mild, moderate, severe and very severe. This is combined with symptom scores and exacerbation history for the ABE assessment.
-
Can COPD be reversed?
No — the airflow obstruction is fixed. But stopping smoking, using the right inhalers, completing pulmonary rehab and preventing exacerbations dramatically change how well and how long you live.
-
Do I need triple inhaler therapy?
Not everyone. Triple therapy (LABA/LAMA/ICS) is reserved for people who keep having exacerbations on dual bronchodilator therapy, or who have an asthmatic overlap.
-
What is pulmonary rehabilitation?
A 6–8 week NHS programme of supervised exercise plus education on breathing techniques, medication and self-management. It improves breathlessness, stamina and quality of life more than most medications.
