Asthma: What You Should Know

Possible Causes Of Occupational Asthma
Asthma is a complicated disease that is composed of two following constituents: the chronic inflammation of the respiratory organs and the periodical attacks of the disease. The cause of the former component has not been explained completely. The only conclusion the physicians all over the world have reached is that an individual, having asthmatic in the family, runs risk to be taken ill with the disease. Nevertheless many people are born without the tendency to have asthma.
All the medics agree that asthma attacks and flare-ups are caused by exposure to a trigger. Similar to any allergic reaction the asthma attack has its sudden outset.
It is the exogenous irritant that serves the reason for any allergic reaction. It’s a kind of the response of the whole organism to so called “invader”, which is perceived as the substance or object different (“alien”) to the body and thus to the immune system.
Let us plunge into the physical process of asthma attack for a moment. The “invader” is perceived by the cells of the immune system. These cells in their turn release certain reactions, a kind of “counteraction”, in order to resist the exogenous irritant. These reactions cause the production and further lump of special protective liquid (mucus) and bronchial spasms. Everything in aggregate occasions the signs of acute asthmatic attack. Sometimes people call asthma reactive airway disease as long as it is one of allergic reaction types.
What concerns occupational asthma, here the role of “invader” plays certain substance or the unusual condition in the workplace of the sufferer. These substances and conditions cause different signs of asthma. As a rule these usual agents are not considered to be detrimental to health. Even though such substances as well as the environmental conditions at the stable working place are the normal ambiance for the majority of the workers, occupational asthma is the typical disease at the following jobs and industries: rubber-processing, chemical and plastics industries; printing, welding, refinery and metal processing; horticulture, landscaping or animal husbandry; and many other similar manufactures and industries.

But that doesn’t mean that everybody, having the job as mentioned above, is bound to develop asthma. Fortunately, most people are not that amenable to this disease. Still the individuals susceptible to respiratory diseases may get other lung diseases or bronchial allergy not necessarily at the work place. The next factors are regarded as the health hazard: different types of allergic reactions, individual exposure to the trigger, any ancestral symptoms of asthma and certainly active or passive smoking.

In order to prevent overreaction of the airways to the exogenous irritant it is obligatory to take the prescribed medication. Alone manifestation or the vivid expression of the asthma symptoms may be caused by everyday conditions, for instance temperature drop or cigarette smoke.
