World COPD Day | Understand Your Lung Function

2024.11.20 World COPD Day

Theme: Know Your Lung Function

November 20, 2024, marks the 23rd World COPD Day. This year's theme, Know Your Lung Function, aims to raise public awareness about COPD, encourage early lung function testing, and promote proactive disease management to improve the quality of life for patients.

What is Chronic Obstructive Pulmonary Disease (COPD)?

COPD is a chronic lung disease characterized by persistent respiratory symptoms, including coughing, excessive sputum production, and shortness of breath. It gradually worsens over time and is often underdiagnosed.

According to global data, COPD is the third leading cause of death worldwide. In China, over 100 million people suffer from COPD, with a prevalence rate of 13.6% among adults aged 40 and above.

What Are the Causes and Risk Factors of COPD?

• Smoking: The primary cause of COPD, affecting both active and passive smokers.

• Air Pollution and Occupational Exposure: Prolonged exposure to pollutants like dust, chemicals, and fumes.

• Respiratory Infections: Frequent lung infections in childhood can increase the risk of COPD in adulthood.

• Genetic Factors: A deficiency in alpha-1 antitrypsin can contribute to COPD development.

Who Is at High Risk for COPD?

Individuals over 35 who experience any of the following should be cautious:

• Persistent cough and sputum production

• Shortness of breath, even with mild activity

• A history of smoking or exposure to secondhand smoke

• Long-term exposure to dust, fumes, or chemical irritants

How to Detect and Diagnose COPD?

When experiencing chronic cough, sputum, or shortness of breath, lung function tests (spirometry) are recommended for early detection.

• Spirometry is the gold standard for diagnosing COPD, measuring how much air a person can exhale and how quickly.

• Early screening and regular check-ups are crucial for at-risk individuals.

How to Prevent COPD Progression?

1. Quit Smoking: The most effective way to prevent and slow COPD progression.

2. Avoid Pollutants: Reduce exposure to harmful air pollutants, including dust and chemicals.

3. Strengthen Lung Function: Engage in breathing exercises and moderate physical activity.

4. Timely Vaccination: Get flu and pneumonia vaccines to prevent respiratory infections.

5. Follow Medical Advice: Use prescribed medications and seek professional guidance for symptom management.
