Understanding respiratory conditions is an important step in managing your lung health. This guide provides clear, accessible information about common chronic respiratory conditions.
Important Note

What is COPD?
Chronic Obstructive Pulmonary Disease (COPD) is a term that describes progressive lung diseases, including emphysema and chronic bronchitis. COPD is characterized by increasing breathlessness and reduced airflow that isn't fully reversible.
COPD develops slowly over years and is most commonly caused by smoking, though long-term exposure to other lung irritants can also contribute. The condition affects millions of people worldwide and is a leading cause of disability.
Key Characteristics of COPD
- Progressive nature - symptoms typically worsen over time
- Airflow limitation that is not fully reversible
- Inflammatory response in the lungs and airways
- Often preventable and treatable, though not curable
Chronic Bronchitis
Chronic bronchitis involves long-term inflammation of the bronchi (airways), leading to increased mucus production and coughing.
Common Signs:
- Persistent cough with mucus
- Cough lasting at least 3 months per year for 2 consecutive years
- Shortness of breath, especially during activity
- Wheezing or chest tightness
Emphysema
Emphysema involves damage to the air sacs (alveoli) in the lungs, reducing the surface area available for gas exchange.
Common Signs:
- Shortness of breath, especially during physical activity
- Chronic cough
- Wheezing
- Reduced exercise tolerance
Risk Factors
Several factors can increase the risk of developing COPD:
- Smoking: The most significant risk factor for COPD
- Long-term exposure to lung irritants: Including air pollution, chemical fumes, and dust
- Genetics: A rare genetic condition called alpha-1 antitrypsin deficiency
- Age: COPD develops slowly, so symptoms often appear in people over 40
- Respiratory infections: Frequent childhood respiratory infections
Stages of COPD
COPD is typically classified into stages based on lung function tests:
- Stage 1 (Mild): Mild airflow limitation; person may not notice symptoms
- Stage 2 (Moderate): Worsening airflow limitation; symptoms become more noticeable
- Stage 3 (Severe): Severe airflow limitation; symptoms significantly impact daily life
- Stage 4 (Very Severe): Very severe airflow limitation; quality of life is seriously impaired
Living with COPD
While COPD is a progressive condition, proper management can help slow its progression, reduce symptoms, and improve quality of life. This includes medical treatment, lifestyle modifications, and ongoing monitoring by healthcare professionals.
When to See a Doctor
Consult a healthcare provider if you experience:
- Persistent cough that lasts for weeks or months
- Shortness of breath, especially during routine activities
- Wheezing or chest tightness
- Frequent respiratory infections
- Bluish lips or fingernail beds (seek immediate care)
- Rapid heartbeat or confusion (seek immediate care)
