  2. Hypotension - Wikipedia

    en.wikipedia.org/wiki/Hypotension

    Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...

  3. Hypertensive emergency - Wikipedia

    A hypertensive emergency is very high blood pressure with potentially life-threatening symptoms and signs of acute damage to one or more organ systems (especially brain, eyes, heart, aorta, or kidneys).

  4. Benzodiazepine withdrawal syndrome - Wikipedia

    en.wikipedia.org/wiki/Benzodiazepine_withdrawal...

    When symptoms increase periodically during protracted withdrawal, physiological changes may be present, including dilated pupils as well as an increase in blood pressure and heart rate. [9] The change in symptoms has been proposed to be due to changes in receptor sensitivity for GABA during the process of tolerance reversal. [25]

  5. Headache - Wikipedia

    en.wikipedia.org/wiki/Headache

    Headache, also known as cephalalgia, is the symptom of pain in the face, head, or neck.It can occur as a migraine, tension-type headache, or cluster headache. [1] [2] There is an increased risk of depression in those with severe headaches.

    en.wikipedia.org/wiki/Intraocular_pressure

    Differences in pressure between the two eyes are often clinically significant, and potentially associated with certain types of glaucoma, as well as iritis or retinal detachment. Intraocular pressure may become elevated due to anatomical problems, inflammation of the eye, genetic factors, or as a side-effect from medication. Intraocular ...

  7. Hyperglycemia - Wikipedia

    en.wikipedia.org/wiki/Hyperglycemia

    Hyperglycemia or Hyperglycaemia is a condition in which an excessive amount of glucose (glucotoxicity) circulates in the blood plasma.This is generally a blood sugar level higher than 11.1 mmol/L (200 mg/dL), but symptoms may not start to become noticeable until even higher values such as 13.9–16.7 mmol/L (~250–300 mg/dL).

  8. Prehypertension - Wikipedia

    en.wikipedia.org/wiki/Prehypertension

    Prehypertension is often asymptomatic (without symptoms) at the time of diagnosis. Only extremely elevated blood pressure (malignant hypertension) can, in rare cases, cause headaches, visual changes, fatigue, or dizziness, but these are nonspecific symptoms which can occur with many other conditions.

  9. Hypertensive encephalopathy - Wikipedia

    en.wikipedia.org/wiki/Hypertensive_encephalopathy

    The impairment of cerebral blood flow that underlies hypertensive encephalopathy is still controversial. Normally, cerebral blood flow is maintained by an autoregulation mechanism that dilates arterioles in response to blood pressure decreases and constricts arterioles in response to blood pressure increases. This autoregulation falters when ...
