What is IPF?

The most common ILD is called Idiopathic Pulmonary Fibrosis (IPF).

IPF is a type of chronic lung disease characterised by a progressive and irreversible scarring and decline in lung function. The cause of this is unknown. Fibrosis occurs when scars form causing excess thickened connective tissue and thickening of the alveolar walls.  This process results in reduced oxygen supply in the blood leading to breathlessness.

What do terms mean in IPF?

  • Idiopathic: any disease or condition where the cause is unknown.
  • Pulmonary: relating to the lungs.
  • Fibrosis: thickening and scarring of connective tissue.
