Introduction to Pulmonary Fibrosis<\/strong><\/h2>

Pulmonary fibrosis is a chronic, progressive lung disease characterized by\u00a0thickening and scarring (fibrosis) of lung tissue<\/strong>, making it difficult to breathe. Over time, the stiffened lung tissue loses its ability to transfer oxygen into the bloodstream, leading to respiratory failure.<\/p>

Key Facts<\/strong><\/h3>

  • Type<\/strong>: Interstitial lung disease (ILD)<\/p><\/li>

  • Progression<\/strong>: Irreversible scarring worsens over time<\/p><\/li>

  • Survival Rate<\/strong>: 3-5 years average after diagnosis (varies by type)<\/p><\/li>

  • Prevalence<\/strong>: Affects ~100,000 people in the U.S., with 50,000 new cases yearly<\/p><\/li><\/ul>

    Causes & Risk Factors<\/strong><\/h2>

    Known Causes<\/strong><\/h3>

    \u2714\u00a0Long-term exposure to toxins<\/strong>\u00a0(asbestos, coal dust, silica)
    \u2714\u00a0Chronic autoimmune diseases<\/strong>\u00a0(RA, lupus, sarcoidosis)
    \u2714\u00a0Radiation therapy<\/strong>\u00a0(for lung\/breast cancer)
    \u2714\u00a0Certain medications<\/strong>\u00a0(chemotherapy, heart drugs like amiodarone)<\/p>

    Risk Factors<\/strong><\/h3>

    • Age<\/strong>: Most patients are 50+ years old<\/p><\/li>

    • Smoking<\/strong>: Increases risk of IPF<\/p><\/li>

    • Genetics<\/strong>: Family history raises susceptibility<\/p><\/li>

    • GERD<\/strong>: Chronic acid reflux may worsen lung damage<\/p><\/li><\/ul>
