What Is Pneumoconiosis?
Pneumoconiosis is a group of lung diseases caused by breathing in harmful dust particles over a long period of time. These particles settle deep in the lungs and can lead to inflammation and permanent scarring.
Pneumoconiosis is usually caused by repeated exposure to dust in workplaces such as mines, construction sites, factories, or industrial settings. Smoking may increase lung damage and worsen symptoms.
Common types include black lung disease from coal dust, silicosis from silica dust, and asbestosis from asbestos exposure.
Symptoms
Symptoms of pneumoconiosis often develop slowly and may not appear until years after exposure begins. As lung scarring worsens, breathing can become more difficult.
Common symptoms include:
- Chronic cough
- Shortness of breath
- Chest tightness
- Wheezing
- Fatigue
- Increased mucus production
How Is It Diagnosed?
Healthcare providers diagnose pneumoconiosis by reviewing your symptoms, medical history, and work exposure history.
Testing may include:
- Chest X-rays
- CT scans
- Pulmonary function tests
- Physical exam
These tests help providers evaluate lung scarring and measure how well the lungs are working.
How Is It Treated?
There is no cure for pneumoconiosis, and lung damage cannot be reversed. Treatment focuses on slowing the disease, managing symptoms, and protecting lung function.
Treatment options may include:
- Avoiding further dust exposure
- Quitting smoking
- Bronchodilator medications
- Oxygen therapy
- Pulmonary rehabilitation
- Flu and pneumonia vaccinations
People with advanced disease may need ongoing respiratory support and regular monitoring.
