What is pulmonary fibrosis?

Pulmonary fibrosis is a condition in which there is scarring of the tissue in the lungs. This tissue gets thick and stiff. That makes it hard for you to breathe, and your blood may not get enough oxygen.

It can be caused by many conditions, including chronic inflammatory processes, infections, environmental agents, exposure to certain gases, exposure to ionizing radiation and chronic conditions.
