Occupational asthma

Occupational asthma occurs when airways react to substances inhaled in the workplace. Examples include wood dust, grain dust, animal dander, chemical vapors and more. In occupational asthma, symptoms often get worse as the work week progresses and get better during weekends or vacations.

Once your lungs become sensitive, they also may start to react to other irritants such as cigarette smoke, house dust or cold air.

The longer a person is exposed to the asthma-causing substance, the worse symptoms will get. If occupational asthma goes untreated, it can lead to permanent lung damage.

Treatment

The best treatment for occupational asthma is to completely avoid the substance that is causing it. Your doctor can prescribe medications to ease your symptoms. Industrial hygienists are professionals trained in workplace air quality and safety. Your doctor may consult them to help you avoid the culprit or recommend protective equipment.
