Chronic obstructive pulmonary disease: diagnosis and management

Written by: | Published:

COPD affects nearly 2% of the UK’s population COPD affects nearly 2% of the UK’s population, and is thought to cause 30,000 deaths a year

Chronic Obstructive Pulmonary Disease (COPD) is an umbrella term to describe airflow limitation that is due to airway and/or alveolar abnormalities usually caused by significant exposure to noxious particles or gases, such as cigarette smoke.1

The airflow limitation is caused by a mixture of small airways disease (eg obstructive bronchiolitis) and parenchymal destruction (emphysema). The combination of chronic inflammation, narrowing of the small airways and reduced lung elastic recoil diminishes the ability of the airways to exchange gas.1

COPD is a leading cause of morbidity and mortality, and the second most common lung disease in the UK after asthma; affecting almost 2% of the UK population. In 2012, almost 30,000 people in the UK died as a result of COPD.1

Worldwide, COPD is the fourth leading cause of death, but it is estimated by the World Health Organisation (WHO) that it will become the third leading cause by 2020.1 Furthermore, it is the second most common cause of emergency admissions to hospital, the fifth largest cause of readmissions in the UK and accounts for over one million hospital bed days in England.2
