What is idiopathic pulmonary fibrosis (IPF)?
The lungs are made up of hundreds of millions of tiny, delicate air sacs called alveoli, which play a vital role in distributing oxygen to the body through the bloodstream. Healthline calls them the “workhorses of your respiratory system,” because they are responsible for providing the body with fresh air and expelling harmful carbon dioxide. With pulmonary fibrosis, these sacs begin to scar and stiffen, making it difficult for them to do their job.
Here’s everything you need to know about idiopathic pulmonary fibrosis, including the causes, symptoms, and treatments.
Who does it affect most?
Most people who develop IPF are between the ages of 50 and 70 (the mean age is 65-70). Men are also more prone to the disease than women. According to a 2021 study, patient numbers are on the rise around the world, likely due to the aging population, an increased awareness of the disease, and more effective diagnostic testing.
How common is it?
IPF is a rare, but serious, disease. According to MedlinePlus, roughly 100,000 Americans are currently living with it, while 30,000 to 40,000 new cases are discovered each year. Worldwide, it affects an estimated 13 to 20 of every 100,000 people.
What are the symptoms?
Common symptoms of IPF include:
- Shortness of breath

What are the complications?
IPF has been linked to a number of co-morbidities, including lung cancer, emphysema, obstructive sleep apnea (OSA), gastroesophageal reflux disease (GERD), and multiple cardiovascular consequences. Scar tissue on the lungs can cause damage to the heart by restricting the flow of oxygen to the body. This may lead to high blood pressure in the lungs (known as pulmonary hypertension) or even heart failure.
