INTRODUCTION TO OCCUPATION ASTHMA
  • Occupational asthma also known as work related
    asthma is a chronic lung disorder. 
  • Occupational asthma occurs when there is a
    reversible inflammation of the airways. 
  • This type of asthma is generally caused by
    exposure to substances at workplace. A patient of
    occupational asthma may develop an allergic
    reaction, irritant reaction, or reaction to
    certain substances at work place, which can
    result in an asthma attack. 
  •  Immune mediated asthma is caused by the external
    stimulus, which initially triggers the bodys
    immune system causing asthma.

Causes of Occupational Asthma
  • There are two elements of occupational asthma-
    one in which there are recurrent attacks and
    another in which there is chronic inflammation.
  • Occupational asthma can be a genetic disorder a
    patient may have a family history of asthma.
  • The most common cause of asthma is the exposure
    to a trigger. The trigger may be an allergic
    reaction.
  • When a person encounters a trigger, the problem
    appears. For example A patient is allergic to
    smoke, when somebody sitting next to him smokes
    it triggers symptoms of occupational asthma.

    cause and the severity of the problem. The
    diagnostic test will include 
  • A chest x-ray
  • Peak flow meter test to detect the patterns
    related to airway process
  • Spirometry test to measure the level of impaired
    breathing
  • Blood test to check for an infection that might
    be causing occupational asthma
