Asthma – What is It? Asthma is a chronic lung disease that obstructs airflow
The obstruction is reversible
It involves difficulty in
breathing due to – Inflammation (swelling)– Mucus in the airways– Tightening of muscles around
the airways

What is work-related asthma?
Pre-existing asthma that is triggered or made worse by exposure to one or more substances in the work-environment

Asthma that is caused by exposure to substances in the work-environment
Signs and symptoms are the same for asthma and work-related asthma

Can asthma be cured? Asthma can be controlled (but not cured) by:
– Avoiding triggers or reducing exposure to triggers– Using medication to control symptoms
Medications - generally two types are used – Controller or long-term drugs
