Lung Fibrosis Disorders

Interstitial Lung Disease (ILD)

A Group of Disorders Causing Lung Scarring and Breathing Difficulty

Interstitial Lung Disease (ILD) refers to a group of lung disorders that cause inflammation and fibrosis (scarring) of lung tissue, leading to stiffness of the lungs and reduced oxygen transfer. Many ILDs are progressive and may require lung transplant in advanced stages.

Understanding

What is Interstitial Lung Disease?

ILD is not a single disease but a group of conditions affecting lung tissue.

It involves:

  • Inflammation of lung interstitium
  • Progressive fibrosis (scarring)
  • Reduced lung elasticity

This results in:

  • Difficulty in breathing
  • Reduced oxygen levels
  • Progressive decline in lung function
Classification

Types of Interstitial Lung Disease

Idiopathic ILD

No known cause (e.g., IPF)

Autoimmune-Related ILD

Associated with diseases like rheumatoid arthritis

Environmental/Occupational ILD

Due to dust, chemicals, or allergens

Drug-Induced ILD

Caused by certain medications

Warning Signs

Early Signs & Symptoms

Persistent cough + unexplained breathlessness → Early evaluation required

Early Stage
Dry cough, mild breathlessness
Progressive Stage
Increasing breathlessness, fatigue
Advanced Stage
Oxygen dependency, cyanosis, clubbing
Persistent cough + unexplained breathlessness → Early evaluation required
Risk Factors

Causes & Risk Factors

Causes
  • Autoimmune diseases
  • Environmental exposures
  • Unknown (idiopathic)
Risk Factors
  • Smoking
  • Occupational exposure
  • Family history
  • Older age

Testing

Diagnosis & Tests

HRCT scan
Key diagnostic tool
Pulmonary function tests (PFT)
Oxygen saturation
Autoimmune panel
Lung biopsy
In selected cases

Check Your Lung Function

Assess your ILD severity

Management

Treatment Options (Before Transplant)

1. Medications
  • Anti-fibrotic drugs
  • Steroids / immunosuppressants
2. Oxygen Therapy
  • For advanced disease
3. Pulmonary Rehabilitation
  • Exercise and breathing training
4. Lifestyle Changes
  • Avoid exposure triggers
  • Vaccinations

When is Lung Transplant Needed?

Progressive disease despite treatment

Severe oxygen dependency

Poor quality of life

Early Diagnosis Improves Outcomes

Timely intervention can slow progression

Medical Management vs Transplant
Medical Management

Stage: Early/Moderate • Goal: Slow progression • Outcome: Stabilization

Lung Transplant

Stage: Advanced • Goal: Replace lungs • Outcome: Life-saving
