Idiopathic pulmonary fibrosis
Idiopathic pulmonary fibrosis (IPF) is a progressive and irreversible lung disease characterized by the scarring (fibrosis) and stiffening of lung tissue. The exact cause of IPF is unknown, hence the term "idiopathic," but it is believed to involve a combination of genetic predisposition, environmental factors, and abnormal wound healing processes in the lungs. IPF primarily affects the interstitial tissue of the lungs, leading to impaired gas exchange and respiratory function.
