Understanding COPD and Breathlessness: A RespCAIR Patient Guide
COPD describes long-term changes in the airways and lungs, most commonly caused by smoking but also by occupational and environmental exposures. It includes conditions previously called chronic bronchitis and emphysema. COPD is diagnosed with lung function testing (spirometry) and assessed alongside symptoms, exercise tolerance and flare-up history.
Common symptoms
- Breathlessness on exertion that has gradually worsened over time
- Persistent cough, often with phlegm
- Frequent chest infections
- Wheeze or chest tightness
- Reduced exercise tolerance
- Repeated flare-ups (exacerbations)
When to seek specialist review
- New or worsening breathlessness affecting daily activities
- Two or more flare-ups in 12 months
- Hospital admission for chest infection or COPD flare-up
- Suspected COPD in current or former smokers
- Need for inhaler optimisation or pulmonary rehabilitation
