Study Notes
Overview of COPD
- Chronic Obstructive Pulmonary Disease (COPD) is a severe and progressive respiratory condition.
- Approximately 10,000 new cases occur annually in Hong Kong due to long-standing damage to the respiratory system.
Causes of COPD
-
Active Smoking:
- Smoking is the predominant cause of COPD, with around 75% of patients having a smoking history.
- Cigarette smoke contains over 7,000 harmful chemicals that damage lung function.
-
Passive Smoking:
- Exposure to secondhand smoke can also contribute to COPD.
- Non-smokers inhaling secondhand smoke experience similar damage to lung function as active smokers.
-
Other Contributing Factors:
- Environmental factors such as air pollution and urban development increase COPD risk.
- Genetic deficiencies and biological differences, including gender, play a role in susceptibility to the disease.
Pathophysiology of COPD
- Smoking causes inflammation and narrowing of the airways, impairing airflow.
- Chronic inhalation of harmful substances leads to the destruction of alveoli (air sacs) in the lungs, causing emphysema.
- Loss of lung elasticity results in air trapping during exhalation, worsening breathing difficulties.
Symptoms and Diagnosis
- Symptoms of COPD worsen over time and include difficulty breathing, chronic cough, and increased mucus production.
- Many individuals may underestimate the seriousness of their condition, leading to delayed treatment.
Prevention and Awareness
- Public education is vital for understanding COPD's causes, symptoms, and treatments.
- Awareness campaigns can help mitigate risks, emphasizing both the dangers of smoking and the impact of passive smoke.
- Knowledge about COPD can empower citizens to seek early detection and adopt preventative measures.
Importance of Gender Considerations
- Women may be more vulnerable to the effects of smoking due to smaller airways, leading to higher risk of COPD development.
- Biological factors complicate the presentation and progression of the disease in women compared to men.
