Pulmonary fibrosis
Pulmonary fibrosis is a group of lung conditions that cause scarring (fibrosis) of the lung tissue. When lungs become scarred, the tissue gets stiffer and is less able to move oxygen into the bloodstream. This can make breathing progressively more difficult over time.
Symptoms
- Increasing shortness of breath, especially with activity
- A dry, persistent cough
- Fatigue
- Unintentional weight loss
- Sometimes clubbing (widening) of the tips of the fingers or toes
Symptoms usually develop slowly, over months or years.
Causes
Pulmonary fibrosis can be caused by a known factor, such as certain medications, radiation therapy, exposure to harmful particles like silica or asbestos, or certain infections. It may also be linked to other medical conditions, such as autoimmune diseases like rheumatoid arthritis or scleroderma. In many people, no clear cause can be found. This is called idiopathic pulmonary fibrosis.
Risk Factors
- Older age, especially over 50
- History of smoking
- Certain jobs that involve dust or fumes, such as construction or mining work
- Having gastroesophageal reflux disease (GERD)
- Family history of pulmonary fibrosis
- Some autoimmune diseases
- Certain medications, such as chemotherapy agents or some heart and antibiotic drugs
How Pulmonary Fibrosis Is Diagnosed
Diagnosis usually begins with a careful review of your symptoms and exposure history, along with a physical exam. Our specialists may recommend tests such as:
- Pulmonary function tests to measure how well your lungs work
- High-resolution CT scan to look for lung scarring
- Blood tests to check for autoimmune causes
- Oxygen level checks (pulse oximetry or arterial blood gas)
- In some cases, bronchoscopy or a lung biopsy if the cause is unclear
A team discussion among pulmonologists, radiologists and pathologists at TidalHealth often helps reach a clear diagnosis.
What to Expect with Pulmonary Fibrosis
The course of pulmonary fibrosis can differ from person to person. Some notice slow changes over many years, while others may see their condition worsen more quickly. Idiopathic pulmonary fibrosis often progresses faster. Early diagnosis and treatment can help slow the disease and improve quality of life.
Managing Pulmonary Fibrosis
Though scarred lung tissue cannot be fully reversed, there are ways to slow progression, ease symptoms and improve daily living. Management often includes:
- Antifibrotic medications for certain types of fibrosis
- Oxygen therapy as needed
- Pulmonary rehabilitation
- Vaccinations
- Quitting smoking
- Treating related conditions like reflux or autoimmune disease
- Lung transplantation in selected cases
Regular follow-ups with a pulmonary specialist are important to track your progress and adjust therapy as needed.
Living with Pulmonary Fibrosis
Supportive measures can help maintain your independence and quality of life. These include pulmonary rehabilitation, breathing techniques, good nutrition, emotional counseling and support groups. Having a coordinated care team at TidalHealth, planning ahead and understanding your care preferences can all contribute to the most comfortable and supported experience possible.
What causes pulmonary fibrosis?
Pulmonary fibrosis can happen because of certain exposures, such as some medications, radiation or environmental and occupational particles. It may also be linked to other medical conditions like autoimmune diseases or chronic heart or liver disease. In some cases, the cause is unknown, called idiopathic pulmonary fibrosis. Genetics can play a role for some families.
What are the first signs I should look for?
Early signs often include shortness of breath with activity and a dry, persistent cough. Fatigue and unexplained weight loss can also occur. If these symptoms gradually worsen, it is important to see your healthcare provider.
How is pulmonary fibrosis diagnosed?
Diagnosis usually includes a detailed medical history and physical exam, pulmonary function tests, a high-resolution CT scan of the chest, blood tests to check for autoimmune disease and sometimes bronchoscopy or lung biopsy. Complex cases are often discussed by a multidisciplinary team at TidalHealth to confirm the diagnosis.
Can pulmonary fibrosis be cured?
There is no cure that reverses existing lung scarring. Certain medications can help slow disease progression for some types, such as antifibrotic drugs for idiopathic pulmonary fibrosis. Lung transplantation may be an option for some people and can extend life.
What treatments are available?
Treatments depend on the cause and severity. Options include antifibrotic medications for eligible people, oxygen therapy, pulmonary rehabilitation, medications to manage symptoms and other health issues, vaccinations and sometimes lung transplant. Lifestyle steps like quitting smoking, eating well and staying as active as possible are also important.
Will I need oxygen therapy?
Many people with pulmonary fibrosis eventually need extra oxygen, especially during physical activity or sleep and sometimes while at rest. Your doctor will recommend oxygen based on your needs and symptoms.
Can pulmonary fibrosis be prevented?
Prevention involves limiting known risks. You can help by not smoking, avoiding harmful environmental exposures, following safety guidelines for hazardous materials, using medications only as directed and managing autoimmune diseases. Some cases, like idiopathic pulmonary fibrosis, cannot currently be prevented because the cause is unknown.
How will pulmonary fibrosis affect my day-to-day life?
Effects can vary widely. With adjustments and supportive care such as pulmonary rehab and oxygen, many people continue daily activities. Pacing yourself, using energy-saving strategies and getting emotional and social support can make a difference.
When should I see a specialist?
If you have unexplained or ongoing shortness of breath, a chronic cough or abnormal lung test results or imaging, it is important to see a pulmonologist experienced in interstitial lung diseases.
Are there clinical trials or new treatments?
Research in pulmonary fibrosis is active. Clinical trials are exploring new medications, anti-inflammatory therapies, ways to repair lung tissue and strategies to better manage symptoms. Ask your healthcare practitioner about available trials and whether you may qualify.
