Question:
Which respiratory disorder causes recurrent alveolar hemorrhage?
Which respiratory disorder causes recurrent alveolar hemorrhage?
Show Hint
Siderosis is also called “iron lung disease” caused by iron dust inhalation.
Updated On: Jun 19, 2026
- Asbestosis
- Silicosis
- Siderosis
- Bronchitis
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand occupational lung diseases.
Respiratory disorders like asbestosis, silicosis, and siderosis are caused by inhalation of different dust particles.
Step 2: Define siderosis.
Siderosis is caused by inhalation of iron dust particles, commonly seen in workers exposed to iron filings.
Step 3: Identify symptom.
Siderosis is associated with irritation and can lead to recurrent alveolar hemorrhage due to iron particle deposition.
Step 4: Analyze other options.
Asbestosis is caused by asbestos fibers, silicosis by silica dust, and bronchitis is inflammation of bronchi, none specifically linked to alveolar hemorrhage.
Step 5: Compare severity.
Siderosis is generally less fibrotic but causes irritation and bleeding in alveoli.
Step 6: Conclusion.
Therefore, the correct answer is siderosis.
