Interstitial fibrosis, also known as interstitial lung disease, is a chronic condition that affects the lungs. It occurs when there is scarring in the interstitium, which is the space between the alveoli and the blood vessels. This scarring can lead to inflammation and damage to the surrounding tissues.
The exact cause of interstitial fibrosis is still unknown, but it is often linked to environmental factors such as exposure to pollutants or chemicals. It can also be caused by genetic predisposition or other health conditions.
The symptoms of interstitial fibrosis can be subtle at first but worsen over time. Common signs include shortness of breath, fatigue, and a persistent cough. In some cases, patients may experience chest tightness or pain.
Diagnosis typically involves a combination of physical examination, imaging tests such as CT scans or MRI, and lung function tests. A biopsy may also be necessary to confirm the diagnosis.
While there is no cure for interstitial fibrosis, treatment focuses on managing symptoms and slowing disease progression. This may involve medication to reduce inflammation or improve lung function, as well as lifestyle changes such as quitting smoking or avoiding environmental triggers.
In severe cases, lung transplantation may be necessary to restore breathing capacity.
