OCCUPATIONAL ASTHMA

Occupational asthma is caused or worsened by exposure to substances in the work environment.  Over 300 workplace substances have been identified as possible irritants that can lead to wheezing, shortness of breath, and lung irritation.  These include chemicals, enzymes, metals, gases, and smokes.  Occupational asthma may develop over time as an allergic response after repeated exposures to an irritant.  It can also occur immediately following inhalation of an irritating substance.  Treatment for occupational asthma is similar to treatment for other types of asthma.  Medications are prescribed to reduce the symptoms.  When irritants can be identified, sufferers may find additional relief by being moved to a different area of the workplace where there is less exposure to the triggering substances.

P.S.  Up to 15 percent of disabling asthma cases in the United States are associated with occupational factors.
