What is Idiopathic Pulmonary Fibrosis?

Idiopathic Pulmonary Fibrosis (IPF) is a chronic, progressive lung disease characterized by scarring (fibrosis) of the lung tissue, which leads to worsening shortness of breath and reduced oxygen exchange. The cause is unknown, hence the term 'idiopathic.' Key facts include that IPF primarily affects older adults, has a median survival of 3–5 years without treatment, and is managed with antifibrotic medications like nintedanib and pirfenidone, along with lung transplant evaluation for eligible patients.
