Idiopathic pulmonary fibrosis (IPF) is a serious lung disease that causes scarring in the lungs, making it difficult to breathe. The scarring, also known as fibrosis, gradually worsens over time, reducing the amount of oxygen that reaches the bloodstream. Approximately 48,000 people in the United States are diagnosed with IPF each year.
IPF symptoms may not be noticeable in the early stages of the disease. As the condition progresses, the following symptoms may develop:
Shortness of breath
Dry, hacking cough that doesn't go away
Crackling sound in the lungs when breathing (heard through a stethoscope)
Fatigue
Chest pain or tightness
Leg swelling
Loss of appetite and weight loss
Clubbing (widening and rounding) of the fingertips and toes
The exact cause of IPF is unknown, hence the term "idiopathic." However, researchers believe that certain factors may increase the risk of developing the disease, including:
Cigarette smoking
Exposure to certain substances, such as wood dust or asbestos
Viral infections, like Epstein-Barr virus, influenza, hepatitis, and herpes
Gastroesophageal reflux disease (GERD)
Family history of IPF (known as familial IPF)
Diagnosing IPF can be challenging, as its symptoms are similar to those of other lung diseases. To confirm an IPF diagnosis, your doctor may recommend the following tests:
Chest scans (X-ray and high-resolution computed tomography)
Breathing tests (spirometry and pulse oximetry)
Blood tests
Skin test (to rule out tuberculosis)
Exercise test
Lung biopsy
Although there is no cure for IPF, treatment can help manage symptoms and slow the progression of the disease. Treatment options may include:
Medications, such as nintedanib (Ofev) and pirfenidone (Esbriet), to slow down the scarring process
Oxygen therapy to help with breathing and maintain oxygen levels in the blood
Pulmonary rehabilitation to improve breathing techniques, exercise tolerance, and overall quality of life
Lung transplantation for severe cases of IPF
For more information on IPF, visit the Pulmonary Fibrosis Foundation, the American Lung Association, or the National Heart, Lung, and Blood Institute.
Living with IPF can be challenging, but there are steps you can take to manage your symptoms and improve your quality of life:
Follow your treatment plan and attend regular check-ups with your doctor
Adopt a healthy lifestyle, including a balanced diet and regular exercise
Quit smoking and avoid exposure to secondhand smoke
Stay up-to-date with vaccinations to reduce the risk of lung infections
Practice relaxation techniques to manage stress
Join a support group to connect with others living with IPF
Remember, everyone's experience with IPF is different. Work closely with your healthcare team to develop a personalized treatment plan and discuss any concerns you may have about your condition and its impact on your life.
