Special interest and expertise in interstitial lung disease and pulmonary fibrosis — conditions that deserve an experienced diagnosis.
Understanding ILD
A Family of Lung Conditions
Interstitial lung disease (ILD) is not one disease — it is a family of conditions that scar or inflame the lung tissue itself. When the lung becomes stiff, the body has to work harder to get oxygen, causing progressive breathlessness and a persistent dry cough.
Some ILDs follow an autoimmune disease or a known exposure; others (like idiopathic pulmonary fibrosis) appear without a clear cause. Because the different forms of ILD behave very differently, the exact diagnosis drives the treatment — and this is where specialist experience matters most.
Common symptoms
Progressive breathlessness on exertion, dry persistent cough, fatigue, subtle crackling sounds in the lungs, swelling of fingertips (clubbing) in some cases.
How it is diagnosed
High-resolution CT (HRCT) chest, lung function testing including diffusion capacity, blood panels for autoimmune markers, and when needed, bronchoscopy with sampling.
Management approach
A multidisciplinary, individualised plan — anti-inflammatory or anti-fibrotic treatment where indicated, oxygen assessment, vaccination, rehabilitation and structured follow-up.
Special Interest
Why ILD Needs a Focused Specialist
ILD is frequently misdiagnosed as asthma, bronchitis or ageing. By the time the correct diagnosis is made, valuable time may have passed. Dr. Sandip Das holds a dedicated clinical interest in ILD and pulmonary fibrosis, and follows this field closely:
Careful HRCT pattern interpretation for the right ILD subtype
Coordination with rheumatology when autoimmune ILD is suspected
Structured disease monitoring — lung function at fixed intervals
Honest, clear counselling about what each stage of care involves
Note for patients
Earlier diagnosis in ILD means earlier treatment — and for many forms of the disease, that translates directly into better symptom control and slower progression.
ILD FAQs
ILD Questions, Answered
What is interstitial lung disease (ILD)?
ILD is a group of more than 200 conditions that cause scarring (fibrosis) or inflammation of the lung tissue between the air sacs. It makes the lungs stiff, so oxygen transfer becomes harder over time.
Is ILD the same as pulmonary fibrosis?
Pulmonary fibrosis is the most recognised form of ILD — including Idiopathic Pulmonary Fibrosis (IPF). Others include sarcoidosis, hypersensitivity pneumonitis and ILD related to autoimmune disease. The exact type determines the treatment.
Is ILD contagious?
No. ILD is not an infection and cannot spread from person to person.
What tests are needed to diagnose ILD?
A high-resolution CT (HRCT) of the chest is the key investigation, along with lung function tests (spirometry, lung volumes, diffusion capacity), blood tests and sometimes bronchoscopy with sampling.
Can ILD be cured?
ILD includes many diseases with different courses. For several types, treatment is very effective in controlling the disease; for fibrotic forms, care focuses on slowing progression, managing symptoms and maintaining quality of life. A precise diagnosis is essential.
What does long-term follow-up involve?
Regular lung function checks, imaging as advised, vaccination, oxygen assessment when needed, nutritional support and pulmonary rehabilitation — all coordinated by the treating specialist.
বাংলায় জানুন — ইন্টারস্টিশিয়াল লাং ডিজিজ
ইন্টারস্টিশিয়াল লাং ডিজিজ (আইএলডি) ফুসফুসের টিস্যুর একদল রোগ, যাতে ফুসফুস শক্ত হয়ে যায় — ফলে অল্প পরিশ্রমেই শ্বাসকষ্ট হয় ও শুকনো কাশি থাকে। এই রোগ প্রায়ই হাঁপানি বা সাধারণ কাশি বলে ভুল হয়, তাই অভিজ্ঞ বুকের ডাক্তারের মাধ্যমে সঠিক পরীক্ষা (হাই-রেজোলিউশন সিটি) খুবই জরুরি। রোগের ধরন অনুযায়ী চিকিৎসা নির্ধারিত হয় — দীর্ঘমেয়াদি যত্ন ও নিয়মিত ফলো-আপে রোগ নিয়ন্ত্রণে রাখা সম্ভব।
