When the action and time of occupational hazard factors exceed a certain limit, a specific functional or organic pathological state may appear in the body, and corresponding clinical signs may appear, which will affect the work ability. Diagnosed by the occupational disease diagnosis institution, this is an occupational disease.
In addition, occupational hazards can also reduce the body's resistance to general diseases, which is manifested by increasing the prevalence of general diseases, or aggravating the disease and prolonging the course of disease. This effect is called nonspecific effect of occupational hazards.
Occupational frequently-occurring diseases, also known as work-related diseases, are different from occupational diseases. Occupational factors are one of the important factors in the occurrence and development of the disease, but they are not the only reasons. Arthritis of miners and low back pain of construction workers are common.
In addition, many occupational hazards will also adversely affect the reproductive function of workers. Long-term exposure can lead to menstrual disorder, premature delivery, abortion, decreased sperm count, deformity and decreased sexual life quality of female workers.
