Pulmonary Fibrosis Q & A

What is pulmonary fibrosis?

Pulmonary fibrosis is a condition in which tissues in your lungs become scarred. As the scarring progressively worsens, the affected areas become thick and stiff. These changes make it hard for your lungs to work, which in turn makes it difficult for you to breathe. It also means that your body is deprived of the oxygen it needs.

What causes pulmonary fibrosis?

Medical experts have identified genetic variations that increase your risk for pulmonary fibrosis. If you have a genetic variation, you’re more susceptible to environmental factors that can damage your lungs and lead to pulmonary fibrosis, such as smoking and exposure to wood and metal dust.

Pulmonary fibrosis may also be caused by viral infections, pneumonia, and autoimmune diseases such as rheumatoid arthritis. Patients who have gastroesophageal reflux disease may breathe small drops of stomach acid into their lungs, which could lead to fibrosis.

In many patients, the cause can’t be identified. When that happens, the condition is called idiopathic pulmonary fibrosis (IPF). IPF is the most common type of pulmonary fibrosis.

What symptoms develop due to pulmonary fibrosis?

The symptoms of pulmonary fibrosis are similar to a variety of lung diseases, many of which progressively worsen over the years. If you have any of these symptoms, schedule an appointment call, Dr. Willoughby:

  • Shortness of breath, especially when you exercise
  • Dry, hacking cough
  • Fast breathing
  • Unintended weight loss
  • Aching joints and muscles
  • Tiredness

Pulmonary fibrosis may cause another symptom, called clubbing, in which the tips of your fingers or toes widen and become round.

How is pulmonary fibrosis treated?

After evaluating your medical history and performing an exam, Dr. Willoughby may order diagnostic imaging and perform lung function tests. Pulmonary tests are done in the office using advanced equipment, so Dr. Willoughby can quickly assess the health of your lungs.

After diagnosing your condition, he works with you to develop an individualized treatment plan that may include one or more of the following:


Several medications are available to reduce inflammation, help prevent lung damage, and suppress your immune system, if needed.

Oxygen therapy

Oxygen therapy boosts blood oxygen and helps reduce shortness of breath.

Pulmonary rehabilitation

Pulmonary rehabilitation may include breathing techniques, exercises, nutritional counseling, and other strategies that help you breathe better and stay healthy.
