What is IPF? 

IPF is a chronic, progressive, fibrotic lung disease which has no clear cause or understood mechanism. IPF is a disease of scarring in the lungs, and the development of the scar tissue is called fibrosis. The scars in the lungs cause the lungs to become stiff, making it hard to breathe. Over time, the scarring becomes so thick that the lungs cannot take in oxygen. With IPF comes a progressive decline in lung function.
