Chronic obstructive pulmonary disease (COPD) is the name for a collection of lung diseases including Chronic Bronchitis, Emphysema and Chronic Obstructive Airways Disease.
People with COPD have difficulties breathing, primarily due to the narrowing of their airways - this is called airflow obstruction.
Typical symptoms of COPD include:
- Increasing breathlessness when active
- A persistent cough with phlegm
- Frequent chest infections
You can get more information on COPD from the NHS Choices website.
