What is asbestosis?
Asbestosis is a long-term lung disease caused by breathing in asbestos fibres over a period of time. These tiny fibres can become trapped in the lungs and cause scarring, which makes it harder to breathe.
It is a serious condition and can take many years to develop after exposure. In the UK, it is most often linked to people who worked in building, shipbuilding, manufacturing, or maintenance before asbestos was banned.
How does asbestos affect the lungs?
When asbestos fibres are inhaled, they can lodge deep in the lungs and stay there. Over time, the body reacts to these fibres and this can lead to inflammation and scarring.
As the scarring worsens, the lungs become stiffer and less able to expand properly. This means oxygen has more difficulty moving into the blood, which can leave a person short of breath.
What are the symptoms?
The main symptom of asbestosis is shortness of breath, especially during physical activity. Some people also develop a persistent dry cough.
Other symptoms can include chest tightness, fatigue, and a feeling of tightness or discomfort in the chest. In more advanced cases, people may notice clubbing of the fingers or swelling caused by strain on the heart.
Who is at risk?
People who worked with asbestos are most at risk, particularly before stricter controls were introduced. This includes trades such as plumbers, electricians, roofers, laggers, builders, and dock workers.
Family members of workers may also have been exposed if asbestos dust was carried home on clothing. Although asbestos is now heavily regulated in the UK, older buildings can still contain asbestos materials.
How is it diagnosed and treated?
Asbestosis is usually diagnosed through a combination of medical history, chest X-rays, CT scans, breathing tests, and sometimes specialist referral. A doctor will want to know about past jobs and possible asbestos exposure.
There is no cure for asbestosis, so treatment focuses on easing symptoms and slowing further damage. This may include inhalers, oxygen therapy, pulmonary rehabilitation, vaccinations, and support to stop smoking if needed.
When should you seek help?
If you have a history of asbestos exposure and develop breathlessness or a lasting cough, speak to your GP. It is important not to ignore symptoms, even if the exposure happened many years ago.
Early assessment can help rule out other causes and make sure you get the right support. In some cases, people with asbestos-related disease may also be entitled to specialist care or compensation advice.
Frequently Asked Questions
Asbestosis is a long-term lung disease caused by breathing in asbestos fibers, which scar the lungs and make breathing harder over time.
Asbestosis is caused by inhaling asbestos fibers, usually through workplace or environmental exposure over many years.
No. Asbestosis is a scarring disease of the lungs, while mesothelioma is a cancer linked to asbestos exposure.
Common symptoms include shortness of breath, persistent dry cough, chest tightness, and fatigue.
Asbestosis usually develops slowly and may take many years, often decades, after asbestos exposure.
People who worked with asbestos-containing materials, such as construction workers, shipyard workers, and insulation workers, are at higher risk.
A single small exposure is less likely to cause asbestosis, but repeated or heavy exposure increases the risk significantly.
Doctors diagnose asbestosis using a medical history, physical exam, imaging tests like chest X-rays or CT scans, and lung function tests.
There is no cure for asbestosis, but treatment can help manage symptoms and slow complications.
Treatment may include oxygen therapy, medications to ease symptoms, pulmonary rehabilitation, and avoiding further asbestos exposure.
Yes. Asbestosis is a progressive disease and can worsen gradually, especially if exposure continues or if lung damage is advanced.
Yes. Smoking can further damage the lungs and increase the risk of serious complications in people with asbestosis.
Yes. Asbestos exposure raises the risk of lung cancer, especially in people who also smoke.
Asbestos exposure is contact with asbestos fibers, while asbestosis is the lung disease that can develop after significant exposure.
Yes. Prevention involves avoiding asbestos exposure, using protective equipment, and following workplace safety rules.
No. Asbestosis is not contagious and cannot be spread from person to person.
Complications can include severe breathing problems, respiratory failure, heart strain, and increased risk of other asbestos-related diseases.
Yes. Anyone with past asbestos exposure who has breathing symptoms should get medical evaluation.
Some asbestos fibers can remain in the lungs for a very long time, contributing to ongoing inflammation and scarring.
Asbestosis can be a serious lung disease because it progressively reduces lung function and can significantly affect quality of life.
