Asbestosis

Asbestosis is a long-term lung condition caused by scarring after heavy exposure to asbestos dust, usually at work. Symptoms typically appear 20 to 30 years after exposure. The scarring cannot be reversed, but its effects can be managed.

What it is

People exposed to asbestos also have a higher risk of mesothelioma and lung cancer, especially if they smoke.

Care includes stopping smoking, vaccinations, pulmonary rehabilitation and, if oxygen levels are low, oxygen therapy.

Common signs

  • Shortness of breath, slowly getting worse
  • A persistent cough
  • Tiredness, chest tightness, clubbed fingertips

How it is usually diagnosed

  • A detailed work history
  • Chest X-ray and CT scan
  • Lung function tests

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Your work history, including employers and dates of exposure
  • Chest CT and X-ray reports
  • Lung function tests over time
  • Respiratory clinic letters

Questions to ask your doctor

  • How much are my lungs affected?
  • What checks do I need for related conditions?
  • Would pulmonary rehabilitation help me?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sudden worsening breathlessness or chest pain
  • Coughing up blood
