Get advanced, accurate diagnosis and personalised treatment for Interstitial Lung Disease (ILD) at Apex Hospitals, where our pulmonology specialists use state-of-the-art technology to detect and manage lung conditions early. With a focus on improving your breathing, slowing disease progression, and enhancing quality of life, we offer compassionate, evidence-based care for every stage of ILD.
Interstitial Lung Disease (ILD) refers to a group of nearly 100 chronic lung disorders that primarily cause inflammation and progressive scarring (fibrosis) of lung tissue. This scarring thickens and stiffens the lungs, reducing their ability to expand fully and take in oxygen. Over time, this makes breathing increasingly difficult and limits the amount of oxygen reaching the bloodstream.
In most cases, people with ILD experience shortness of breath, especially during physical activity, and may have a persistent dry cough. The condition can be caused by prolonged exposure to harmful substances such as asbestos, silica, or coal dust, or may develop as a complication of certain autoimmune diseases like rheumatoid arthritis. In some cases, however, the exact cause remains unknown.
The inflammation associated with ILD can affect different parts of the lungs:
Once fibrosis (scarring) occurs, it cannot be reversed. Treatment focuses on slowing further lung damage, easing symptoms, and improving quality of life. Depending on the type and severity of ILD, medications may help reduce inflammation and slow disease progression, but some people may eventually require a lung transplant.
The course of ILD varies from person to person; it may remain stable for years, progress slowly, or worsen rapidly. Symptoms can range from mild to severe, making regular monitoring and timely medical care essential.
The symptoms of ILD can develop gradually over months or years, or in some cases, progress quickly. They often worsen over time as lung scarring increases.
Common symptoms include:
Other possible symptoms:
Interstitial lung disease can result from a variety of factors that damage the lung tissue, leading to inflammation and scarring (fibrosis). In some cases, the cause remains unknown, which is referred to as idiopathic ILD.
Some viral, bacterial, or fungal infections can trigger lung inflammation that leads to ILD.
In many patients, no specific cause can be found. The most common idiopathic form is Idiopathic Pulmonary Fibrosis (IPF), which tends to worsen over time without a clear reason.
You should consult a pulmonologist if you experience:
If your doctor suspects interstitial lung disease (ILD), they will perform a series of tests and assessments to confirm the diagnosis, identify the underlying cause, and determine the best treatment plan. The evaluation process may include:
Your doctor will ask about your breathing problems, cough, and how long you’ve had symptoms. They will inquire about exposure to dust, chemicals, or mold, smoking habits, travel history, family history of lung disease, and any existing autoimmune conditions.
Using a stethoscope, your doctor will listen for crackling or “Velcro-like” sounds in your lungs. They may also check your oxygen levels using a pulse oximeter.
Measures how well your lungs take in and release air, and how efficiently oxygen moves into your blood. Common tests include spirometry and the diffusing capacity test (DLCO).
Help rule out infections and detect autoimmune or inflammatory diseases.
A 6-minute walk test may be performed to see how your lungs respond to physical activity.
In some cases, a small sample of lung tissue is taken to confirm the diagnosis and identify the type of ILD.
Detecting interstitial lung disease (ILD) at an early stage can make a big difference in how the condition is managed and how well you feel in the long term.
While lung scarring (fibrosis) cannot be reversed, early treatment can help slow down further damage and preserve lung function.
In the early stages, there are usually more choices for medication and therapy, which can help control inflammation and improve breathing.
Prompt treatment can help reduce breathlessness, cough, and fatigue, improving your ability to perform daily activities.
Early diagnosis lowers the risk of serious complications such as pulmonary hypertension or severe oxygen shortage.
With early intervention, you can maintain independence and mobility for a longer time.
People diagnosed early may qualify for research studies offering access to new and promising treatments.
Early awareness gives you time to make changes such as avoiding harmful exposures, improving nutrition, and starting pulmonary rehabilitation.
"Many ILD patients mistake their symptoms for asthma or aging. Early evaluation with HRCT and lung function testing is key to preventing severe lung damage." – Dr Vijayant Solanki, Senior Consultant- Pulmonary Medicine, Apex Hospitals
