IPF is the result of a cascade of events that involve inflammatory, immune, and fibrotic processes in the lung. However, despite many studies and hypotheses, the stimulus that begins the progression remains unknown. Speculation has revolved around viral and genetic causes, but no good evidence has been found to support either theory. However, it’s clear that chronic inflammation plays an important role. Inflammation develops the injury and the fibrosis that ultimately distorts and impairs the structure and function of the alveolocapillary gas exchange surface.
IPF is slightly more common in men than in women and is more common in smokers than in nonsmokers. It usually affects people ages 50 to 70.

The term 'prevalence' of Pulmonary fibrosis usually refers to the estimated population of people who are managing Pulmonary fibrosis at any given time. The term 'incidence' of Pulmonary fibrosis refers to the annual diagnosis rate, or the number of new cases of Pulmonary fibrosis diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
