Chronic stress is the physiological or psychological response induced by a long-term internal or external stressor. [1] The stressor, either physically present or recollected, will produce the same effect and trigger a chronic stress response. [ 1 ]
Epidemiology has its limits at the point where an inference is made that the relationship between an agent and a disease is causal (general causation) and where the magnitude of excess risk attributed to the agent has been determined; that is, epidemiology addresses whether an agent can cause disease, not whether an agent did cause a specific ...

Chronic stress is a term sometimes used to differentiate it from acute stress. Definitions differ, and may be along the lines of continual activation of the stress response, [ 34 ] stress that causes an allostatic shift in bodily functions, [ 3 ] or just as "prolonged stress". [ 35 ]
Worldwide, mortality rates have decreased as both technological and medical advancements have led to a tremendous decrease in infectious diseases. With fewer people dying from infectious diseases, there is a rising prevalence of chronic and/or degenerative diseases in the older surviving population. [citation needed]
This is known as chronic hypertension, which elevates mortality from cardiovascular disease and stroke. Similarly, a chronically high carbohydrate diet requires chronically high blood glucose and leads to chronically high levels of insulin that increase in anticipation of the need to manage the high level of carbohydrates.
The epidemiology of chronic disease is diverse and the epidemiology of some chronic diseases can change in response to new treatments. In the treatment of HIV, the success of anti-retroviral therapies means that many patients will experience this infection as a chronic disease that for many will span several decades of their chronic life. [32]
The weathering hypothesis was initially proposed as a sociological explanation for health disparities, but it is closely related to biological theories like the allostatic load model, which proposes that an individual's exposure to repeated or chronic stress over their lifetime has physiological consequences which can be measured through ...
