Pulmonary fibrosis is a condition in which scarring occurs in the lungs. It can be caused by an infection (such as tuberculosis or pneumonia) or injury or by breathing certain materials, such as asbestos. But sometimes no cause can be found for pulmonary fibrosis. Pulmonary fibrosis makes the lungs less elastic and can lead to breathing problems.
Symptoms of pulmonary fibrosis include:
- Shortness of breath.
- Decreased ability to be active.
- Dry cough.
Treatment for pulmonary fibrosis aims to make breathing easier and slow the progress of the disease.
