COPD (Chronic Obstructive Pulmonary Disease)
COPD is long-term lung damage that makes breathing harder over time, usually from smoking or long-term smoke exposure. It cannot be reversed but can be slowed and managed.
Causes & risk factors
- Smoking (the most common cause)
- Long-term exposure to biomass/cooking smoke or dust
- Air pollution and workplace fumes
- Repeated chest infections in childhood
- A rare inherited enzyme deficiency (alpha-1 antitrypsin)
Common symptoms
- Breathlessness on activity
- Long-term cough with phlegm
- Wheezing
- Tiredness
- Frequent chest infections
Tests & diagnosis
- Spirometry (lung function test)
- Chest X-ray
- CT chest scan
- Blood oxygen (pulse oximetry)
Treatment & management
- Stopping smoking is the single most important step
- Inhalers (bronchodilators, sometimes inhaled steroids)
- Pulmonary rehabilitation exercise programmes
- Vaccines (flu, pneumonia) to prevent infections
- Oxygen therapy in advanced cases
When to see a doctor urgently
- Sudden severe breathlessness — call your local emergency number now
- Chest pain, blue lips or confusion — emergency
- Coughing up more or discoloured phlegm with fever
- Symptoms getting steadily worse or interfering with daily life

Frequently asked questions
Is COPD the same as asthma?
No. COPD is usually caused by smoking and mainly affects older adults with permanent airway damage, while asthma symptoms come and go and are often reversible.
Does quitting smoking help if I already have COPD?
Yes. Stopping smoking at any stage slows further lung damage and is the most effective treatment.
