What are the first signs of COPD?

COPD is a long-term condition in which airflow through the lungs becomes limited. Early changes can be gradual: you may notice that walking uphill, climbing stairs, or keeping up with usual activities causes more [Shortness of Breath](/symptoms/shortness-of-breath/) than before. A daily [Cough](/symptoms/cough/) may produce [Coughing Up Phlegm](/symptoms/coughing-up-phlegm/), and some people develop [Wheezing](/symptoms/wheezing/) or [Chest Tightness](/symptoms/chest-tightness/). These symptoms have other possible causes, so they do not establish COPD by themselves.

Book a clinical assessment if cough or breathlessness persists, worsens, or limits routine activities. A clinician will ask about smoking, workplace or household exposures, infections, and the pattern of symptoms. [Spirometry](/treatments/diagnostics-and-screening/spirometry/) measures how air moves in and out of the lungs and may be part of the assessment. If you smoke, a [Smoking Cessation Programme](/treatments/lifestyle-and-wellness/smoking-cessation-programme/) can support stopping and protect lung function.

Seek urgent help for severe or rapidly worsening breathlessness, blue or grey lips, confusion, fainting, or chest pain. A sudden change from your usual cough or phlegm, especially with fever or marked weakness, also deserves prompt medical advice. For ongoing symptoms without emergency features, arrange a [Chronic Disease Review](/treatments/consultations-and-assessment/chronic-disease-review/).

Ask whether spirometry is appropriate, what else could explain your symptoms, how to reduce smoke or dust exposure, and which changes should prompt urgent help.
