Interstitial Lung Disease Specialists in Sinthee, Kolkata, West Bengal

What is Interstitial Lung Disease?

Interstitial lung disease refers to a large group of disorders that cause progressive scarring, or fibrosis, of the tissue surrounding the lungs' air sacs, gradually stiffening the lungs and making it harder for oxygen to pass into the bloodstream. Many forms of the disease have no identifiable cause and are termed idiopathic, while others result from long-term exposure to environmental or occupational irritants, autoimmune conditions, or certain medications. The scarring process is typically irreversible, so the primary goal of treatment is to slow disease progression and preserve lung function rather than reverse existing damage. Symptoms often develop gradually over months to years, which can delay diagnosis until significant lung damage has already occurred. High-resolution CT scanning and, in some cases, lung biopsy are used to characterise the specific type of disease and guide treatment decisions.

Causes of Interstitial Lung Disease

Causes include chronic exposure to environmental or occupational irritants such as asbestos, silica dust, or certain moulds and bird droppings, autoimmune diseases such as rheumatoid arthritis and scleroderma, and certain medications or radiation therapy. A significant proportion of cases, particularly idiopathic pulmonary fibrosis, have no clearly identifiable cause, though genetic predisposition and smoking are recognised risk factors. Age over 50 and a history of gastroesophageal reflux are also associated with higher risk in some forms.

Symptoms of Interstitial Lung Disease

Progressive shortness of breath especially with exertion, persistent dry cough, fatigue, unintended weight loss, clubbing of the fingers or toes, chest discomfort, crackling sounds in the lungs on examination, in advanced disease bluish discolouration of the skin

Treatment & Types of Interstitial Lung Disease in Sinthee, Kolkata, West Bengal

Treatment depends on the underlying cause, with antifibrotic medications used to slow disease progression in idiopathic pulmonary fibrosis, and immunosuppressive therapy used for cases linked to autoimmune conditions. Supplemental oxygen therapy and pulmonary rehabilitation help manage symptoms and improve quality of life as the disease progresses. Lung transplantation may be considered for eligible patients with advanced disease that has not responded to other treatments.
