Doctors don't know what causes idiopathic pulmonary fibrosis (IPF). They think that something inside or outside of the lungs attacks the lungs again and again over time.
These attacks injure the lungs and cause scarring in the tissue inside and between the air sacs. This makes it harder for oxygen to pass through the air sac walls into the bloodstream.
Doctors think the following things may increase your risk for IPF:
• Cigarette smoking
• Viral infections, including Epstein-Barr virus (which causes mononucleosis), influenza A virus, hepatitis C virus, HIV-a virus, and herpes virus 6
• Exposure to environmental pollutants, including inorganic dust (silica and hard metal dusts), organic dust (bacteria and animal proteins), and gases and fumes
• The use of certain medicines, including:
Genetics also may play a role in causing IPF. Some families have at least two members who have IPF.
Scientists have found that 9 out of 10 people who have IPF also have gastroesophageal reflux disease (GERD). GERD is a condition in which acid from your stomach backs up into your throat.
As a result, some scientists think that some people who have GERD may breathe in tiny drops of acid from their stomachs on a regular basis. The acid may then injure the lungs and lead to IPF. More research must be done to confirm this theory.
The signs and symptoms of idiopathic pulmonary fibrosis (IPF) develop over time. Once they occur, they're likely to get worse over time.read more
Treatment of idiopathic pulmonary fibrosis usually is based on your age, medical history, any medical problems you may have, and how much the IPF hasread more
