Stress ulceration is a single or multiple fundic mucosal ulcers that causes upper gastrointestinal bleeding, and develops during the severe physiologic stress of serious illness. It can also cause mucosal erosions and superficial hemorrhages in patients who are critically ill, or in those who are under extreme physiologic stress, causing blood ...
Aspects of the wider community have also been implicated, [13] including employment problems, socioeconomic inequality, lack of social cohesion, problems linked to migration, and features of particular societies and cultures. Mental stress is a common cause of mental illnesses, so finding a coping solution to cope with mental stress would be ...
A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism. [1] Psychologically speaking, a stressor can be events or environments that individuals might consider demanding, challenging, and/or threatening individual safety.
A link has been suggested between chronic stress and cardiovascular disease. [43] Stress appears to play a role in hypertension, and may further predispose people to other conditions associated with hypertension. [48] Stress may precipitate abuse of drugs and/or alcohol. [5] Stress may also contribute to aging and chronic diseases in aging ...
There is a wide range of chronic stressors, but most entail relatively prolonged problems, conflicts and threats that people encounter on a daily basis. [2] Several chronic stressors have been identified as associated with disease and mortality including "neighbourhood environment, financial strain, interpersonal stress, work stress and ...
Theories suggest a link between brain activation of stress-related biochemicals (including neuropeptides) and the effects these chemicals have on areas of the heart, especially neuropeptide Y. [26] More specifically, adrenal stimulation by the sympathetic nervous system has been noted in cases ranging from physical events such as ischemic ...
An etiological agent of disease may require an independent co-factor, and be subject to a promoter (increases expression) to cause disease. An example of all the above, which was recognized late, is that peptic ulcer disease may be induced by stress, requires the presence of acid secretion in the stomach, and has primary etiology in ...
The importance of homeostasis is to regulate the stress levels encountered on the body to reduce allostatic load. Dysfunctional allostasis causes allostatic load to increase which may, over time, lead to disease, sometimes with decompensation of the problem controlled by allostasis. Allostatic load effects can be measured in the body.
