Occupational Asthma

Abstract 10.5152/gghs.2019.030

Asthma is a respiratory disease characterized by airway obstruction that is partially or completely reversible, either spontaneously or with treatment; airway inflammation; and increased airway responsiveness to a variety of stimuli. Occupational asthma is asthma that is caused by environmental exposures in the workplace. Several hundred agents have been reported to cause occupational asthma. Pre-existing asthma or airway hyper-responsiveness, with symptoms worsened by work exposure to irritants or physical stimuli, is usually classified separately as work-aggravated asthma. There is general agreement that occupational asthma has become the most prevalent occupational lung disease in developed countries. however, that in many countries asthma of occupational etiology causes a largely unrecognized burden of disease and disability with high economic and non-economic costs. Much of this public health and economic burden is potentially preventable by identifying and controlling or eliminating the workplace exposures causing the asthma.
