Emphysema’s Effects on the Body: Breathlessness, Weight Loss, Fatigue, and More

Emphysema destroys alveolar walls, reducing gas‑exchange surface and lung elasticity. Systemic effects:

• Dyspnea (exertional → resting)
• Chronic cough ± sputum
• Wheezing
• Weight loss & muscle wasting (increased work of breathing)
• Fatigue (hypoxemia, hypercapnia)
• Peripheral edema (cor pulmonale → right heart failure)
• Depression/anxiety (chronic illness burden)

Early diagnosis (spirometry), smoking cessation, bronchodilators, pulmonary rehab, and oxygen therapy improve survival and quality of life.
