Risk factors

By Mayo Clinic staff

You're at increased risk of developing occupational asthma if:

  • You have existing allergies or asthma. Although this can increase your risk, many people who have allergies or asthma do jobs that expose them to lung irritants and never have symptoms.
  • Allergies or asthma run in your family. You are more likely to develop asthma if your parents have allergies or asthma.
  • You work around known asthma triggers. Some substances are known to be lung irritants and asthma triggers. A number of workplace substances are known to cause occupational asthma.
