Silicosis
Lung Disease Caused by Long-Term Inhalation of Silica Dust
Silicosis is an occupational lung disease caused by inhaling fine silica dust over a prolonged period. It leads to lung inflammation, fibrosis (scarring), and progressive breathing difficulty. The damage is permanent and can worsen even after exposure stops.

Silicosis is preventable with proper workplace safety measures.
What is Silicosis?
Silicosis occurs when fine silica particles are inhaled and deposited in the lungs.
This causes:
- Chronic inflammation
- Formation of fibrotic nodules
- Progressive lung scarring
Resulting in:
- Reduced lung capacity
- Impaired oxygen exchange
- Increased risk of infections (including TB)
Early Signs & Symptoms
Mild Cough
Shortness of Breath
Weight Loss
Causes & Risk Factors
Primary Cause
Inhalation of crystalline silica dust
High-Risk Occupations & Risk Factors
- Mining
- Construction
- Stone cutting and polishing
- Sandblasting
- Long exposure duration
- Lack of protective equipment
Disease Progression
Simple Silicosis
Small nodules
Mild symptoms
Progressive Massive Fibrosis (PMF)
Large fibrotic masses
Significant lung impairment
Severe Stage
Extensive fibrosis
Oxygen dependency
End Stage Lung Disease
Respiratory failure
Lung transplant required
Diagnosis & Tests
Chest X-ray
HRCT scan
Pulmonary function tests
Occupational history assessment
Assess your occupational exposure risk
Understand your lung health
Treatment Options (Before Transplant)
1. Stop Exposure
- Immediate removal from dust exposure
2. Symptom Management
- Bronchodilators
- Anti-inflammatory drugs
3. Pulmonary Rehab
- Breathing exercises
4. Oxygen Therapy
- For advanced disease
When is Lung Transplant Needed?
Severe lung fibrosis develops
Oxygen dependency
Poor quality of life
Prevention is the Most Effective Strategy
Workplace safety can prevent disease progression
Important Consideration: Preventable Occupational Disease
• Use protective masks and ventilation • Regular screening for exposed workers • Early detection improves outcomes
Medical Management vs Transplant
Medical Management
Stage: Early/Moderate • Goal: Slow progression • Outcome: Limited reversal
Lung Transplant
Stage: Advanced • Goal: Replace lungs • Outcome: Life-saving
Lung Transplant Options
Single Lung Transplant
Selected cases
Double Lung Transplant
Preferred in advanced fibrosis
