	'''Occupational asthma''' is a type of [[asthma]] that is directly related to exposure to substances in the workplace. It is characterized by the development of asthma symptoms such as wheezing, coughing, chest tightness, and shortness of breath due to inhalation of specific substances that are present in the work environment.

'''Occupational asthma''' is a type of [[asthma]] that is caused by inhaling certain substances in the workplace. These substances, known as [[asthmagens]], can cause the airways to become inflamed and narrowed, leading to symptoms such as wheezing, coughing, chest tightness, and shortness of breath.

== Causes ==
Occupational asthma can be caused by a wide range of substances, including:
* [[Dust]] from wood, grain, or textiles
* [[Chemicals]] used in manufacturing, such as isocyanates, anhydrides, and amines
* [[Animal dander]], urine, or proteins
* [[Enzymes]] used in detergents or pharmaceuticals
* [[Metals]], such as platinum, chromium, and nickel sulfate
* [[Plants]], such as latex, flour, and certain types of grain

== Symptoms ==
The symptoms of occupational asthma are similar to those of other types of asthma, and can include:
* [[Wheezing]]
* [[Coughing]]
* [[Chest tightness]]
* [[Shortness of breath]]
* [[Eye irritation]]
* [[Nasal congestion]]

== Diagnosis ==
Occupational asthma can be diagnosed by a [[doctor]] based on a person's symptoms, medical history, and the results of certain tests. These tests can include:
* [[Spirometry]], a test that measures how much air a person can breathe in and out, and how quickly
* [[Peak flow monitoring]], a test that measures how quickly a person can exhale
* [[Allergy testing]], to determine if a person is allergic to certain substances
* [[Bronchial provocation testing]], to see how a person's airways respond to specific substances

== Treatment ==
The primary treatment for occupational asthma is to avoid exposure to the substance that is causing the symptoms. This may involve changing jobs or tasks, or using protective equipment. Medications may also be used to manage symptoms, including:
* [[Bronchodilators]], which help to open the airways
* [[Inhaled corticosteroids]], which help to reduce inflammation in the airways
* [[Leukotriene modifiers]], which help to prevent asthma symptoms

== Prevention ==
Prevention of occupational asthma involves reducing exposure to asthmagens in the workplace. This can be achieved through:
* [[Substitution]], replacing a hazardous substance with a less hazardous one
* [[Isolation]], separating the worker from the hazardous substance
* [[Ventilation]], removing the hazardous substance from the air
* [[Personal protective equipment]], such as respirators
