Effects of occupational stress on the gastrointestinal tract

Abstract

The aim of this review is to provide a general overview of the relationship between occupational stress and gastrointestinal alterations. The International Labour Organization suggests occupational health includes psychological aspects to achieve mental well-being. However, the definition of health risks for an occupation includes biological, chemical, physical and ergonomic factors but does not address psychological stress or other affective disorders. Nevertheless, multiple investigations have studied occupational stress and its physiological consequences, focusing on specific risk groups and occupations considered stressful. Among the physiological effects of stress, gastrointestinal tract (GIT) alterations are highly prevalent. The relationship between occupational stress and GIT diseases is evident in everyday clinical practice; however, the usual strategy is to attack the effects but not the root of the problem. That is, in clinics, occupational stress is recognized as a source of GIT problems, but employers do not ascribe it enough importance as a risk factor, in general, and for gastrointestinal health, in particular. The identification, stratification, measurement and evaluation of stress and its associated corrective strategies, particularly for occupational stress, are important topics to address in the near future to establish the basis for considering stress as an important risk factor in occupational health.© 2013 Baishideng Publishing Group Co., Limited.

In particular, jobs that produce privation, fatigue, chronic mental anxiety and a long past history of tension, frustration, resentment, psychological disturbance or emotional conflict have been shown to produce gastric ulcers. Irritable bowel syndrome and functional dyspepsia also have significant co-morbidity with mood alterations. Workers with unipolar depression have been shown to be more prone to present irritable bowel syndrome-like symptoms. Moreover, three systems are known to participate in the GIT alterations of workers: sympathetic autonomic nervous system, the hypothalamic-pituitary-adrenal axis and genetic factors.Huerta-Franco MR, Vargas-Luna M, Tienda P, DelgadilloHoltfort I, Balleza-Ordaz M, Flores-Hernandez C.

Psychosocial Impact of Irritable Bowel Syndrome Among Teachers in Tabuk, Saudi Arabia

“…The autonomic nervous system, hypothalamic-pituitary axis, and genetic factors participate in gastrointestinal tract alterations in workers [12] moreover, change in the intestinal microbiota can interact with the immune and nervous systems leading to GIT symptoms [13]. In the present study continuous stress was commoner among participants with irritable bowel syndrome with significant statistical difference confirming the above observation.…”

“…Onset of pain related to a change in the frequency of stool 3. Onset of pain associated with a change in the form (appearance) of stool without any underlying systemic, organic or metabolic causes [12]. A structured questionnaire was used to collect sociodemographic factors, absence from work or sick leave due to IBS symptoms, partner employment, house type (own vs. rent), income, income adequacy, participation in care of children, continuous stress, excessive, and sleeping hours.…”

Burnout, Occupational Stress, Health and Road Accidents among Bus Drivers: Barriers and Challenges for Prevention

“…Empirical evidence collected over the past 50 years suggests that compared with other occupational groups, professional drivers tend to have a higher prevalence of cardiovascular [54,55], musculoskeletal [46], and gastrointestinal diseases [35]. Regarding with mental health problems, it was found that depression, anxiety, and post-traumatic stress disorders are highly prevalent in professional drivers, and are contributing factors for work-related accidents [6,8,54].…”

“…Burnout is associated with negative health outcomes such as anxiety [29], depression [29,30], sleep disturbances [31][32][33], headache [34], gastrointestinal disease [35], hypertension [36], muscle tension [34], and chronic fatigue [37], and especially in the case of professional drivers, with poor job performance [38,39]. Burnout is also associated with negative organizational outcomes such as absenteeism and high turnover intention [40,41].…”

Occupational skin diseases and prevention among sanitation workers in China

“…As working in the open air, sanitation workers are also suffered from rain, snow, sand, cold and ultraviolet rays. These factors lead to harmful effects on the overall health of the sanitation workers, including skin 2 , hair 3 , respiratory 4 , gastrointestinal 5 , urogenital 2 , as well as orthopedic problems 6 . Skin serves as a natural barrier from pathogens and damage between the internal and external environment in body defense, and is predisposed to disease when subjected to environmental stressors.…”
