Understanding COPD: Symptoms, Diagnosis & Treatment Options

Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease characterized by persistent airflow limitation. It includes chronic bronchitis and emphysema.

Common Symptoms

• Shortness of breath (dyspnea), especially with exertion
• Chronic cough, often productive
• Wheezing
• Chest tightness
• Fatigue, reduced exercise tolerance
• Unintended weight loss (advanced)
• Peripheral edema (cor pulmonale sign)

Diagnosis

Clinical Assessment

History: symptom onset, severity, activity limitation, smoking/exposure history, comorbidities.

Physical Exam

Lung auscultation (wheezing, decreased breath sounds), heart rate, blood pressure, oxygen saturation.

Spirometry (Gold Standard)

Post-bronchodilator FEV₁/FVC < 0.70 confirms persistent airflow limitation. Severity staged by FEV₁ % predicted.

Additional Tests

• Lung volumes (hyperinflation)
• Diffusion capacity (emphysema assessment)
• Chest X-ray/CT (rule out other pathology)
• Arterial blood gas (severe disease)

Treatment

No cure, but management slows progression and improves quality of life.

• Bronchodilators: SABA, LAMA, LABA (first-line)
• Inhaled Corticosteroids (ICS): Added for frequent exacerbations/eosinophilic inflammation
• Pulmonary Rehabilitation: Exercise, education, breathing techniques—proven to improve dyspnea and exercise capacity
• Oxygen Therapy: For severe resting hypoxemia (PaO₂ ≤ 55 mmHg)
• Vaccinations: Influenza, pneumococcal, COVID-19
• Exacerbation Management: Short-course oral corticosteroids, antibiotics if purulent sputum
• Advanced Options: Lung volume reduction, transplantation (select cases)

Early diagnosis and intervention are crucial. If you have symptoms, see your doctor promptly.
