Your lungs are an essential part of your body. They help you breathe, facilitate the exchange of oxygen and carbon dioxide between the environment and the bloodstream, and protect your body from harmful substances. However, what happens if your lung is scarred?

Lung scarring, also known as pulmonary fibrosis, is the thickening and scarring of the tissue around and between the air sacs known as alveoli in the lungs, which make it difficult for oxygen to pass into the bloodstream. Many factors can contribute to this condition, some of which are shared with us by Dr Satish C Reddy, Senior Consultant Pulmonologist, CARE Hospitals, Hitech City, Hyderabad.

What Is Pulmonary Fibrosis?

Dr Reddy described lung scarring due to pulmonary fibrosis as a serious and often challenging health condition where the lungs gradually lose their ability to function effectively.

"As the lung tissue becomes thickened and stiff, breathing becomes increasingly difficult, leading to a significant decline in quality of life," he explained, adding that understanding the underlying causes of this scarring, from environmental exposures to genetic factors, is crucial for effective management and prevention.

Factors That Contribute To Lung Scarring

There are a range of factors that increase the risk of lung scarring. Some of the key contributors are:

• Chronic inflammatory conditions like autoimmune diseases (e.g., rheumatoid arthritis)
• Exposure to harmful substances
• Long-term exposure to pollutants, infections, and radiation therapy

In addition, environmental toxins such as asbestos, silica dust, and industrial chemicals can severely damage lung tissue. When inhaled, these substances cause chronic inflammation and injury, leading to the gradual formation of scar tissue.

It is also important to note that some people are genetically predisposed to pulmonary fibrosis.

Dr Reddy said, “Certain genetic mutations and a family history of the disease can increase susceptibility. Research continues to explore specific genetic markers associated with the disease, which could help in identifying at-risk individuals and guiding preventive strategies.”

Lung Scarring Without Any Cause

Idiopathic pulmonary fibrosis is a progressive lung disorder characterised by lung scarring without any particular cause.

According to StatPearls Publishing, the condition typically affects older individuals, usually after the age of 50.

Studies have shown that men are more likely to develop IPF than women. The prevalence of IPF varies across different regions, with higher rates reported in Europe and North America compared to other areas. In the United States, the estimated prevalence of IPF is around 58.7 cases per 100,000 people, research noted.

How To Reduce The Risk

To reduce the risk of pulmonary fibrosis, here are some expert-recommended tips:

• Focus on avoiding known risk factors and maintaining lung health
• Reduce exposure to environmental toxins
• Wear protective gear in high-risk jobs
• Quit smoking
• Go for regular medical check-ups, especially if you're undergoing treatments known to affect the lungs.
• Manage existing health conditions and be aware of medication side effects.
