About Pulmonary Fibrosis

What is Pulmonary Fibrosis?

Pulmonary Fibrosis is a life-limiting lung disease caused by scarring of the lungs.

Pulmonary = Of the Lungs
Fibrosis = Scarring

This scarring causes the lungs to become stiffer and the transfer of oxygen from lungs to the body becomes more difficult. As the disease progresses more of the lung tissue becomes scarred.

There are many causes of pulmonary fibrosis including:

  • acid reflux
  • smoking
  • family history
  • exposure to certain types of dust
  • in some cases there is no known cause – this is called idiopathic pulmonary fibrosis (IPF)


The symptoms of PF include the following:

  • shortness of breath
  • persistant dry cough
  • tiredness
  • weight loss and loss of appetite
  • clubbed fingers
