10 COPD facts
In this article we will describe 10 facts about COPD (chronic obstructive pulmonary disease).
Key Points
-
COPD (chronic obstructive pulmonary disease) is a progressive lung disease characterised by airflow obstruction.
-
Smoking is the primary risk factor.
-
Early diagnosis and management can improve quality of life and reduce exacerbations.
-
Multidisciplinary care, including smoking cessation, pulmonary rehabilitation, and pharmacological treatment, is essential.
1. Definition
- COPD is a chronic inflammatory lung disease causing airflow limitation, making breathing difficult. It encompasses chronic bronchitis and emphysema, often co-existing.
-
Chronic Bronchitis: Inflammation of the bronchial tubes, leading to persistent cough and mucus production
-
Emphysema: Damage to alveoli, reducing lung elasticity and gas exchange
-
Mixed COPD: Combination of chronic bronchitis and emphysema.
2. Epidemiology
-
COPD affects over 1.2 million people in the UK.
-
Prevalence increases with age, affecting 10% of those over 65.
-
COPD is the fifth leading cause of death globally.
3. Risk Factors
-
Smoking: Primary risk factor (80% of cases).
-
Age
-

5. Symptoms
