Occupational Asthma

General Information on Occupational Asthma

Occupational asthma is a narrowing of the airways which causes difficulty breathing. It occurs when inhaling allergen causing vapors or particles in a work related environment. Some examples of substances that contribute to occupational asthma are: dust, animal dander, mold, and certain chemicals. Symptoms may develop during work hours but often don’t start until a few hours after work. Occupational asthma may cause symptoms that come and go for a week or longer, making it difficult to make a connection between the symptoms and the work place. Symptoms often worsen with repeated exposure.

Treatments For Occupational Asthma

When diagnosing occupational asthma, a doctor asks the person about the symptoms and the possibility of exposure to a substance known to cause asthma. An allergy test may be given. During an allergy test, the doctor places the suspected allergen on the skin, to test for an allergic reaction. When making a diagnosis becomes difficult, doctors may use an inhalation challenge test. During the inhalation challenge test, the person inhales small amounts of the suspected substance and is monitored for symptoms. If occupational asthma is confirmed it is suggested that the person change jobs, if possible. Prolonged exposure can lead to more severe and persistent asthma. Treatment is the same for other types of asthma. Drugs that open the airways may be given, usually in the form of an inhaler. Corticosteroids may be given for a short period of time if the person is experiencing severe attacks.
