What causes Pulmonary Fibrosis?
While the cause of Pulmonary Fibrosis remains a mystery, what researchers do know is that Pulmonary Fibrosis involves changes in the lung’s normal healing process. Pulmonary Fibrosis’ chronic cycle of injury leads to an exaggerated or uncontrolled healing response that, over time, produces fibrous scar tissue. This scarring, in turn, causes the lung’s tiny air sacs, called alveoli, to thicken and stiffen-rendering the lungs less able to function and provide the body with the oxygen it needs.
