  2. Stress-related disorders - Wikipedia

    en.wikipedia.org/wiki/Stress-related_disorders

    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 ...

  3. Cell damage - Wikipedia

    en.wikipedia.org/wiki/Cell_damage

    Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors. Cell damage can be reversible or irreversible.

  4. Hs and Ts - Wikipedia

    en.wikipedia.org/wiki/Hs_and_Ts

    Acidosis (hydrogen cation excess) is an abnormal pH in the body as a result of lactic acidosis which occurs in prolonged hypoxia and in severe infection, diabetic ketoacidosis, kidney failure causing uremia, or ingestion of toxic agents or overdose of pharmacological agents, such as aspirin and other salicylates, ethanol, ethylene glycol and other alcohols, tricyclic antidepressants, isoniazid ...

  5. Takotsubo cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Takotsubo_cardiomyopathy

    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] Specifically, adrenal stimulation by the sympathetic nervous system has been seen in cases ranging from physical events such as ischemic stroke, to ...

  6. Orthostatic hypotension - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_hypotension

    Apart from treating underlying reversible causes (e.g., stopping or reducing certain medications, treating autoimmune causes), several measures can improve the symptoms of orthostatic hypotension and prevent episodes of syncope (fainting). Even small increases in the blood pressure may be sufficient to maintain blood flow to the brain on standing.

  7. Chronic stress - Wikipedia

    en.wikipedia.org/wiki/Chronic_stress

    However, the problem arises when there is a persistent threat. First-time exposure to a stressor will trigger an acute stress response in the body; however, repeated and continuous exposure causes the stressor to become chronic. [4] McEwen and Stellar (1993) argued there is a "hidden cost of chronic stress to the body over long time periods". [8]

  8. Deformation (engineering) - Wikipedia

    en.wikipedia.org/wiki/Deformation_(engineering)

    The relationship between stress and strain is generally linear and reversible up until the yield point and the deformation is elastic. Elasticity in materials occurs when applied stress does not surpass the energy required to break molecular bonds, allowing the material to deform reversibly and return to its original shape once the stress is ...

  9. Repetitive strain injury - Wikipedia

    Cumulative trauma disorders, repetitive stress injuries, repetitive motion injuries or disorders, occupational or sports overuse syndromes: Poor ergonomic techniques by computer users is one of many causes of repetitive strain injury.
