Symptoms

The most common symptoms of pulmonary fibrosis are dry, persistent cough and shortness of breath. Symptoms may be mild or even absent early in the disease process. As the lungs develop more scar tissue, symptoms worsen. Shortness of breath initially occurs with exercise, but as the disease progresses patients may become breathless while taking part in everyday activities, such as showering, getting dressed, speaking on the phone, or even eating.

Due to a lack of oxygen in the blood, some people with pulmonary fibrosis may also have “clubbing” of the fingertips. Clubbing is a thickening of the flesh under the fingernails, causing the nails to curve downward. It is not specific to pulmonary fibrosis or idiopathic pulmonary fibrosis and occurs in other diseases of the lungs, heart, and liver, and can also be present at birth.
