Idiopathic pulmonary fibrosis (IPF) is a lung condition that scars your lungs and reduces the efficiency of your breathing.
Idiopathic means the cause is not known, but researchers now believe that the body creates fibrosis (scarring) in response to an injury to the lung.
A team of several experts (called a multi-disciplinary team), often at specialist hospitals, will collect information about you before making a diagnosis. This is because there are many types of pulmonary fibrosis.
Treatment for IPF aims to slow the rate of scarring in the lung and treat the symptoms.
