COPD Key facts
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, causing 3.23 million deaths in 2019.
Nearly 90% of COPD deaths in those under 70 years of age occur in low- and middle-income countries (LMIC).
COPD causes persistent and progressive respiratory symptoms, including difficulty in breathing, cough and phlegm production.
COPD results from long-term exposure to harmful gases and particles combined with individual factors, including events which influence lung growth in childhood and genetics.
Environmental exposure to tobacco smoke, indoor air pollution and occupational dusts, fumes and chemicals are important risk factors for COPD.
Early diagnosis and treatment, including smoking cessation support, is needed to slow the progression of symptoms and reduce flare-ups.

Learn about COPD
Chronic obstructive pulmonary disease (COPD) is a common, preventable and treatable chronic lung disease which affects men and women worldwide.
Abnormalities in the small airways of the lungs lead to limitation of airflow in and out of the lungs. Several processes cause the airways to become narrow. There may be destruction of parts of the lung, mucus blocking the airways, and inflammation and swelling of the airway lining.
COPD is sometimes called emphysema or chronic bronchitis. Emphysema usually refers to destruction of the tiny air sacs at the end of the airways in the lungs. Chronic bronchitis refers to a chronic cough with the production of phlegm resulting from inflammation in the airways.

There is no cure for COPD, but early diagnosis and treatment are important to slow the progression of symptoms and reduce the risk of flare-ups.
COPD should be suspected if a person has typical symptoms, and the diagnosis confirmed by a breathing test called spirometry, which measures how the lungs are working. In low- and middle-income countries, spirometry is often not available and so the diagnosis may be missed.
