World COPD Day: what you should know

COPD is a long-term lung condition in which airflow is persistently limited. Smoking is a frequent cause, although other inhaled irritants and exposures can contribute. Symptoms may include breathlessness during activity, a continuing cough, wheezing, chest tightness, and bringing up phlegm. COPD commonly presents with these breathing symptoms, but each symptom can also have other causes.

Symptoms can change gradually, which can make it easy to adjust daily activities without noticing how much breathing has changed. A review helps establish the cause and identify support that fits the person’s symptoms and routine.

Arrange a clinical review for a persistent cough, wheeze, phlegm, or breathlessness that interferes with ordinary activity. Spirometry is a breathing test that measures how air moves out of the lungs and may help assess COPD. Bring details of symptoms, smoking or work exposures, medicines, and previous chest illnesses to the appointment.

If you smoke, stopping can reduce further smoke exposure to the lungs. Support programmes can help with a quit plan, withdrawal symptoms, and relapse prevention. Use inhalers only as prescribed and ask a clinician to check your technique.

Seek urgent medical care for severe or rapidly worsening breathlessness, blue or grey lips, new confusion, chest pain, coughing blood, or difficulty speaking because of breathlessness. Contact a clinician promptly when a usual cough or phlegm changes markedly, fever develops with breathing symptoms, or prescribed treatment is no longer giving usual relief.

Ask whether spirometry is appropriate, what may be causing your symptoms, and how to use each inhaler. If you smoke, ask which quitting support suits your previous attempts and daily triggers.
