Our Responsum for PF app is closing as of October 2023. We’ll continue to provide access to helpful information for the PF community via our website.
What Are the Stages of Pulmonary Fibrosis?
Pulmonary fibrosis (PF) is a chronic disease that progresses or worsens over time—though how quickly or slowly it progresses for each individual varies. While some chronic diseases have definable stages that allow you to understand how fast the disease is or will advance, PF is different. “There is no formal staging system for pulmonary fibrosis. Physicians use different factors…to describe the disease as mild, moderate, severe, or very severe,” according to the American Lung Association (ALA).
