Chronic Obstructive Pulmonary Disease (COPD) is a progressive long‐term lung disease that involves inflammation and thickening of the airways.¹ Over time the disease makes it more difficult to breathe because the airways are obstructed, restricting the flow of air in and out of the lungs.¹
When this happens less oxygen reaches the blood, and it becomes harder to get rid of the waste gas carbon dioxide.¹
COPD is made up of two chronic conditions: chronic bronchitis which is a persistent cough with mucus, and emphysema which is characterised by the destruction of lung tissue.¹
The main cause of COPD is tobacco smoking, with smokers at a higher risk of respiratory problems and mortality.2 Other risk factors include exposure to air pollution, and occupational exposure to dust and chemicals.3
According to the latest figures from the World Health Organization4 65 million people across the globe are living with moderate to severe COPD. Over the next decade deaths from COPD are projected to increase by more than 30%4 and by 2030 it is expected to become the third leading cause of death worldwide.5
Your doctor will diagnose COPD based on your symptoms and medical history.
