Occupational asthma is a lung disorder triggered by exposure to dust, vapors, gases, fumes or other irritants at a patient’s workplace. Breathing difficulties, such as wheezing and coughing, are typical symptoms associated with this workplace disorder.

People with traditional asthma may experience symptoms of occupational asthma after moving into a new work environment or using new materials. It may also occur in people who have no history of asthma and those who have asthma but have not experienced asthma symptoms for a number of years. Most episodes are triggered by exposure to a substance that either provokes an allergic reaction or an irritant reaction. Many agents in the workplace are potential sources of occupational asthma symptoms. Protein molecules and various chemicals are among the most common triggers.

Those with symptoms of occupational asthma should see a physician to make sure the disorder is properly diagnosed. Left untreated, occupational asthma symptoms are likely to get worse with repeated exposures, leading to long-term health problems. Many employers have shown a willingness to help employees find or create a more suitable work environment.
