According to the National Institutes for Health (NIH), PF affects 200,000 Americans(1)(2). PF is a condition in which the lung tissue becomes thickened, stiff, and scarred1. The development of the scar tissue is called fibrosis. As lung tissue becomes scarred and thicker, it loses its ability to transfer oxygen into the bloodstream. As a result, the brain and other organs don’t get the oxygen they need. In some cases, doctors can determine the cause of the fibrosis, but in most cases, there is no known cause. When there is no known cause for the fibrosis the disease is called idiopathic pulmonary fibrosis or IPF.
