Introduction

1. Pharmacological therapy, including glucocorticoids, immunosuppressants or cytotoxic agents, antioxidants, antifibrotic drugs, and receptor inhibitors. 2. Surgical treatment, such as lung transplantation, which has become a primary therapeutic modality for various end-stage lung diseases. 3. Other supportive treatments, including oxygen therapy to alleviate hypoxemia in patients, and mechanical ventilation for IPF complicated by respiratory failure.

Pulmonary fibrosis refers to the end-stage pathological change common to a broad group of lung diseases, characterized by fibroblast proliferation, excessive accumulation of extracellular matrix, inflammatory injury, and structural destruction of lung tissue. So, how is pulmonary fibrosis treated? The following section addresses this question.

How Is Pulmonary Fibrosis Treated?

1. Pharmacological Therapy

Pharmacological treatment includes corticosteroids, immunosuppressants or cytotoxic agents, antioxidants, antifibrotic drugs, receptor inhibitors, immunomodulators, other medications, and gene therapy. However, it is crucial to use these medications strictly under physician supervision to avoid exacerbating the disease. Additionally, pulmonary rehabilitation—a comprehensive, multidisciplinary intervention specifically designed for patients with chronic lung disease who experience symptoms and reduced functional capacity—can alleviate symptoms, improve physical function, and stabilize or slow disease progression.

2. Surgical Treatment

Lung transplantation has become a primary therapeutic option for various end-stage lung diseases. In patients with idiopathic pulmonary fibrosis (IPF), lung transplantation improves survival rates and quality of life, with a 5-year survival rate reaching 50–56%. Pulmonary rehabilitation also plays an important role; its components include respiratory physiological training, muscular conditioning (e.g., whole-body exercise and respiratory muscle training), nutritional support, and psychological interventions. Nevertheless, current treatments—regardless of modality—can only slow disease progression and relieve symptoms.

3. Other Therapies

Oxygen therapy can effectively alleviate hypoxemia in patients. For IPF patients with respiratory failure, endotracheal intubation and mechanical ventilation are generally avoided. Noninvasive positive-pressure ventilation (NIPPV) may improve oxygenation and prolong survival in some IPF patients. However, endotracheal intubation and mechanical ventilation are typically not recommended for patients with poor-prognosis, end-stage pulmonary fibrosis. Therefore, patients should always seek treatment guidance from qualified physicians.

The above outlines current approaches to treating pulmonary fibrosis. We hope this information proves helpful.

What causes pulmonary fibrosis?

Pulmonary fibrosis is the end-stage pathological change of interstitial lung disease, which may be associated with environmental factors, medications, long-term smoking, pneumonia, tuberculosis, and other factors. Patients should seek timely medical attention at a hospital and follow medical advice to improve their condition through general treatment, medication, and other approaches. During treatment, adequate rest is essential; heavy physical labor and strenuous exercise should be avoided, and sufficient sleep should be ensured.
