Occupational 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.
    Occupational asthma can appear in any work
    environment be, it a store, office, or hospital.
    There are two main types of occupational asthma.
    Irritant induced asthma directly triggers the
    airways and causes inflammation of the airways.
    Immune mediated asthma is caused by the external
    stimulus, which initially triggers the bodys
    immune system causing asthma.

3
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.

4
Symptoms
  • The symptoms of occupational asthma may appear
    when a patient reaches his workplace and symptoms
    disappear after a patient leaves the workplace.
    The symptoms may come and go frequently. However,
    many of the patients do not have any symptom.
    Common symptoms of occupational asthma 
  • Chest pain
  • Fatigue
  • Coughing
  • Conjunctivitis
  • Rhinorreha (runny nose)
  • Difficulty breathing
  • Wheezing
  • Chest tightness

5
Diagnosis of Occupational Asthma
  • A doctor will start a diagnosis by asking a
    patient about their symptoms, medical history and
    may conduct a physical exam. After that, a doctor
    will order a diagnostic test to know the exact
    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

6
Treatments
  • The most effective treatment of occupational
    asthma is to avoid the trigger this may include
    changing the workplace where there is less
    exposure to the triggers. The main aim of
    the treatment of occupational asthma is to
    prevent asthma attacks, to maintain normal lung
    function, to maintain healthy breathing cycle.
    Asthma in its initial stages can be easily
    treated by taking a few preventive measures. Some
    preventive measures are 
  • Wear a mask while at the workplace.
  • Quit smoking and avoid sitting next to a person
    who smokes.
