Your lungs have tiny, delicate air sacs that need to be flexible like a balloon to help you breathe. In pulmonary fibrosis, these sacs become damaged and develop scar tissue, which is thick and stiff. This scarring makes it very hard for the lungs to stretch, meaning you have to work harder to take in a full breath.
The term 'unspecified' means that your doctor has confirmed you have this lung scarring, but they have not yet identified a specific cause or a known medical condition, like an autoimmune disease, that is driving the process. Because the lungs are not working as efficiently, your body often struggles to get enough oxygen during daily activities.
Common Symptoms
- A dry, nagging cough that does not go away.
- Shortness of breath, especially when you are walking, climbing stairs, or being active.
- Feeling unusually tired or exhausted.

- In some cases, the tips of your fingers or toes may appear rounded or wider than usual, a change known as clubbing.
