What is occupational asthma?

Occupational asthma is asthma that is caused by, or made worse by, something in the workplace. It can affect people in many different jobs, from cleaning and construction to healthcare and manufacturing.

It happens when the lungs become sensitive to a substance at work. This substance may be breathed in over time, or it may trigger symptoms after a single exposure.

Common workplace causes

Many different substances can lead to occupational asthma. Common examples include flour dust, wood dust, chemical fumes, paints, isocyanates, and animal proteins.

Some jobs carry a higher risk than others. These include baking, welding, spray painting, farming, hairdressing, healthcare, and laboratory work.

Symptoms to look out for

The symptoms are similar to other types of asthma. They may include wheezing, coughing, chest tightness, and shortness of breath.

One clue is that symptoms are often worse during the working week and improve when the person is away from work, such as at weekends or on holiday. Early symptoms may be mild, so they can be easy to miss.

How occupational asthma is diagnosed

If occupational asthma is suspected, a GP may ask about the person’s job, duties, and exposure to dusts, fumes, or chemicals. They may also arrange tests to check lung function.

It is helpful to keep a record of symptoms and when they happen. An occupational health specialist or respiratory clinic may also be involved in confirming the diagnosis.

Treatment and what to do next

Treatment usually includes standard asthma medicines, such as inhalers, to control symptoms and reduce inflammation. However, the most important step is to avoid or reduce exposure to the cause at work.

In some cases, a person may need to change tasks, improve ventilation, or use better protective controls. For some people, changing job or workplace may be necessary if symptoms are severe or continue to worsen.

Why early action matters

Occupational asthma can become long-term if it is not recognised early. The sooner the cause is identified, the better the chance of preventing further damage to the lungs.

Anyone who thinks their asthma may be linked to work should speak to their GP as soon as possible. They should also report concerns to their employer or occupational health team so that the workplace risks can be addressed.

Frequently Asked Questions

What is occupational asthma?

Occupational asthma is asthma caused by conditions or substances in the workplace, such as dusts, fumes, chemicals, or animal proteins.

How is occupational asthma different from regular asthma?

Occupational asthma is triggered or worsened by exposures at work, while regular asthma may be caused by many non-work-related factors.

What are common causes of occupational asthma?

Common causes include flour dust, wood dust, isocyanates, latex, animal dander, cleaning agents, and certain metal or chemical fumes.

Who is at risk for occupational asthma?

People who work with irritant or sensitizing substances, such as bakers, healthcare workers, painters, cleaners, farmers, and laboratory staff, are at higher risk.

What are the symptoms of occupational asthma?

Symptoms can include wheezing, coughing, chest tightness, and shortness of breath, often worsening during or after work.

Can occupational asthma develop suddenly?

Yes, it can develop after a single high exposure or more gradually after repeated workplace exposures over time.

Does occupational asthma improve away from work?

Symptoms often improve on days off, weekends, or vacations, especially in the early stages.

How is occupational asthma diagnosed?

Diagnosis usually involves a medical history, work exposure review, lung function tests, and sometimes allergy testing or peak flow monitoring at and away from work.

Why is identifying occupational asthma important?

Finding the cause is important because continued exposure can make asthma worse and may cause long-term lung problems.

Can occupational asthma be cured?

It may improve greatly if the exposure is removed early, but some people continue to have asthma even after leaving the workplace exposure.

What is a sensitizer in occupational asthma?

A sensitizer is a substance that causes the immune system to react over time, leading to asthma symptoms when exposed again.

What is irritant-induced occupational asthma?

This type develops after exposure to a strong irritant, such as smoke or chemical fumes, that damages the airways and causes asthma-like symptoms.

How is occupational asthma treated?

Treatment may include asthma medicines like inhalers and avoiding or reducing exposure to the triggering substance.

Should a person with occupational asthma change jobs?

Sometimes changing duties or jobs is needed if exposure cannot be controlled enough to prevent symptoms.

Can workplace masks prevent occupational asthma?

Masks may reduce exposure in some situations, but they do not always fully prevent occupational asthma, especially with sensitizers.

Is occupational asthma the same as work-exacerbated asthma?

No. Occupational asthma is caused by work exposures, while work-exacerbated asthma is pre-existing asthma that becomes worse at work.

Can occupational asthma be covered by workers' compensation?

In many places, occupational asthma may be considered a work-related illness and could qualify for workers' compensation.

What should I do if I think my asthma is related to my job?

See a healthcare professional promptly, track when symptoms occur, and note possible workplace exposures and symptom patterns.

Can children get occupational asthma?

Occupational asthma is usually seen in adults because it is related to workplace exposures, but young workers can also develop it.

How can occupational asthma be prevented?

Prevention includes controlling workplace exposures, improving ventilation, using safe handling practices, substituting safer substances, and using proper protective equipment.
