Idiopathic Pulmonary Fibrosis

What is Idiopathic Pulmonary Fibrosis?

Idiopathic pulmonary fibrosis (IPF) is a serious lung disease. It occurs when the tissue around air sacs (alveoli) in the lungs gets thick and stiff. This makes it harder to breathe. Over time this stiff tissue causes permanent scarring in the lungs, which is called fibrosis.(1)
