Is there a relationship between pulmonary fibrosis and the common cold?


Hello Dr.
Yang: I recently had a chest X-ray, and the results showed "fibrosis in the left and right lung apices." This is the first time I've seen this; the results from about a year ago were normal.
Could having a slight cold (or not being fully recovered) at the time of the X-ray have affected the results? Or would you recommend following up with a pulmonologist? Thank you.

Dr. Yang Wenda reply Pulmonology


Hello Mr.
Yang: Fibrosis typically indicates a history of inflammation that has left a scar.
Based on your description, it is likely that the inflammation occurred within the past year (since the X-ray was normal a year ago).
The apices of both lungs are common sites for pulmonary tuberculosis, so I recommend that you check if any family members or close friends have a history of tuberculosis.
For follow-up, I suggest you return to your original hospital every 3 to 6 months for regular monitoring over the past year; compare the X-rays for any changes (progression).
If you experience a cough lasting more than three weeks without improvement, please seek evaluation at a pulmonology clinic promptly.
Best wishes!

More Info


Lung fibrosis, also known as pulmonary fibrosis, is a condition characterized by the thickening and stiffening of lung tissue, which can lead to progressive respiratory difficulties. The presence of fibrosis can be detected through imaging studies such as chest X-rays or CT scans. In your case, the recent X-ray findings of "left and right lung apex fibrosis" indicate that there has been a change in your lung structure compared to previous imaging, which was reported as normal about a year ago.

Regarding your question about the potential impact of having a cold or respiratory symptoms at the time of the X-ray, it is important to understand that acute respiratory infections, such as the common cold, typically do not cause lung fibrosis. However, they can lead to temporary changes in lung function and may exacerbate pre-existing conditions, such as asthma or chronic obstructive pulmonary disease (COPD). If you were experiencing symptoms of a cold during the imaging, it is unlikely that this would directly cause the observed fibrosis, but it could potentially mask or complicate the interpretation of the X-ray findings.

It is advisable to follow up with a pulmonologist or a chest specialist for further evaluation and monitoring of the lung fibrosis. They may recommend additional imaging studies, pulmonary function tests, or even a biopsy if necessary, to determine the underlying cause of the fibrosis. The progression of lung fibrosis can vary significantly among individuals, and early intervention can be crucial in managing symptoms and slowing disease progression.

In terms of symptoms, lung fibrosis can lead to chronic cough, shortness of breath, and fatigue. These symptoms can be exacerbated by cold weather, as cold air can irritate the airways and make breathing more difficult, especially for individuals with pre-existing lung conditions. Therefore, if you are experiencing respiratory symptoms, it is essential to monitor them closely and seek medical attention if they worsen.

In summary, while having a cold at the time of your X-ray is unlikely to have caused the observed lung fibrosis, it is important to follow up with a healthcare professional to assess the significance of the findings and to determine an appropriate management plan. Regular monitoring and proactive management are key to maintaining lung health, especially in the presence of fibrosis.
