Occupational asthma is a type of asthma characterized by variable airflow limitation or hyper-responsiveness or inflammation due to causes and conditions attributable to a particular occupational environment and not to stimuli encountered outside the workplace. Prevalence of occupational asthma in Switzerland is quite lesser than Asian countries. 66% men, 21% smokers (9 women and 29 men), and only 7% were ex-smokers showed symptoms of occupational asthma. On testing with alpha-amylase inhibitor 0.19,a sensitization rate of 65% individuals with baker's asthma occurred.
Avoiding the workplace irritant that causes your symptoms is critical. However, once you become sensitive to a substance, tiny amounts may trigger asthma symptoms, even if you wear a mask or respirator. You may need medications to control your symptoms and prevent asthma attacks. Treating asthma involves both preventing symptoms and treating an asthma attack in progress. The right medication for you depends on a number of things, including your age, symptoms, asthma triggers and what seems to work best to keep your asthma under control. Reducing exposure to the triggers at work is the most important step to reduce the occurrence of occupational asthma. It's also important to use appropriate asthma medication to prevent symptoms.
