Chronic obstructive pulmonary disease (COPD) - what is COPD?

What is COPD?

Chronic Obstructive Pulmonary Disease (COPD) is not one single disease but an umbrella term used to describe chronic lung diseases that cause limitations in lung airflow. The more familiar terms 'chronic bronchitis' and 'emphysema' are no longer used, but are now included within the COPD diagnosis.

The most common symptoms of COPD are breathlessness, or a 'need for air', excessive sputum production, and a chronic cough. However, COPD is not just simply a "smoker's cough", but a under-diagnosed, life threatening lung disease that may progressively lead to death.

Main risk factors for COPD

  • Tobacco smoking
  • Indoor air pollution (such as biomass fuel used for cooking and heating)
  • Outdoor air pollution
  • Occupational dusts and chemicals (vapours, irritants, and fumes)
