Occupational asthma is asthma that’s caused or worsened by breathing in fumes, gases, dust or other potentially harmful substances while one is “on the job.” Symptoms usually get worse as the workweek progresses, go away during weekends and vacations, and recur when you return to work. But they can occur both at work and away from work!!

Occupational asthma could be the first time when patient has asthma symptoms, or patient may have had asthma as a child and it has returned. If there is a history of underlying asthma, it may be worsened by being exposed to certain substances at work.

Risk Factors

  • Existing allergies or asthma.
  • Allergies or asthma runs in family
  • Working around substances that are known to be lung irritants and asthma triggers.
  • Smoking

Prevalence

Up to 15% of asthma cases in the United States may be job-related.
