About Chronic Obstructive Pulmonary Disease
Progressive lung disease causing breathing difficulties
COPD includes emphysema and chronic bronchitis, causing airflow limitation that is not fully reversible.
It is primarily caused by long-term exposure to irritating gases or particulate matter, most commonly from cigarette smoke.
Editorial update (28 September 2026): structured medical content awaits clinical reviewer sign-off.
How assessment may be approached
A clinician may review cough, breathlessness, wheeze, fever, triggers, smoking or exposures, medicines and infection risk. Examination and tests such as oxygen saturation, imaging, lung function or sputum testing may be considered.
Care can range from self-care and monitoring to inhaler review, antibiotics for a confirmed indication, allergy control, rehabilitation or specialist assessment. Ask how to use medicines and what improvement should occur.
When to seek prompt care
Seek urgent care for severe breathlessness, blue lips or face, confusion, chest pain, coughing blood, low oxygen saturation if measured, inability to speak in sentences or rapidly worsening symptoms.
