Information about pulmonary fibrosis (PF) can be hard to find. This article aims to answer some of the frequently asked questions (FAQs) about this disease.
What is PF?
PF belongs to a group of lung disorders called interstitial lung diseases (ILD). It is a progressive disease marked by fibrosis, or scarring of lung tissue, that makes breathing difficult and affects lung function.
Are there different types of PF?
There are several types of PF. Idiopathic pulmonary fibrosis (IPF), or PF of no known cause, is the most common type, affecting nearly 13 to 20 people per 100,000 worldwide. There also is a very rare type of PF that can be inherited, called familial pulmonary fibrosis (FPF).
What causes PF?
The causes of PF can be highly variable. These include autoimmune diseases, occupational or environmental health hazards, medication, and in some cases, genetics.
What are the symptoms of PF?
PF is a progressive disease and can affect anyone, although it is seen more commonly in middle-aged and older adults. The symptoms of PF include breathlessness, cough, weight loss, fatigue, aching joints and muscles, and clubbing (the widening and rounding of fingers and toes).
How will doctors know I have PF?
How is the severity of PF determined?
- FVC greater than 75% — mild disease
- FVC between 50 and 75% — moderate disease
- FVC between 25 and 49% — severe disease
- FVC lower than 25% — very severe disease
Can PF be inherited?
Is PF contagious?
No. PF is not contagious and does not spread from person to person.
What treatment options are there?
What is life expectancy like?
PF has a poor prognosis and most patients live about three to five years after diagnosis. Several factors — age, gender, ethnicity, physical features, comorbidities (other illnesses), smoking, physiologic factors, and pathologic factors — can affect prognosis.
Can pulmonary fibrosis be prevented?
While there are no established ways of preventing PF, potential risk factors such as smoking and exposure to environmental pollutants can certainly be avoided. If there are family members affected by PF, undergoing genetic tests can help in planning ways to reduce the risk of the disease developing.
Does exercise help in slowing disease progression?
Although exercise does not slow down PF progression by itself, it helps keep the lungs, heart, and breathing muscles strong. In some cases, however, exercise can be counterproductive. That makes it important for people with PF to check with their doctors before starting an exercise regimen. Often, a pulmonary rehabilitation program is the best way to learn proper breathing and exercise techniques for PF patients.
Should diet be modified?
For PT patients who are overweight, it helps for them to incorporate some changes into their diet. Excess weight can impede comfortable breathing. Large meals also can put pressure on the diaphragm, which can cause discomfort and breathing difficulties. People with PF should consult their doctors or a dietitian, who will be able to suggest a diet and eating schedule tailored to their symptoms.
Does air travel pose issues for PF patients?
Yes. The pressurized cabin inside an airplane can make breathing difficult. It is important for patients to obtain a fitness certificate from their doctor before embarking on a flight. That certificate also must be shown to the airline staff while making the reservation. An FAA-approved portable oxygen cylinder may be carried on board, and can be used during takeoff or landing, if needed. Check with the airline well in advance to determine if the carrier is able to provide one, if necessary.
