What causes Pulmonary Fibrosis?

It is very difficult to pin-point the causes of Pulmonary Fibrosis (PF). Idiopathic Pulmonary Fibrosis (IPF) is PF with an unknown cause. This is the most common type of PF so often doctors are unable to determine the cause of the disease.
However, there are some factors that can increase the chances for PF such as:

• Family history of PF
• Smoking
• Certain autoimmune diseases
• Pneumonia
• Tuberculosis
• GERD (Acid reflux disease)
• Exposure to asbestos, certain dusts and gases
• Certain drugs for treating cancer, heart disease, and antibiotics
• Certain viral infections

Because there are so many different potential causes for PF and the symptoms of PF are similar to other lung diseases, it can very difficult for doctors to diagnose it.
