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 ...
Severe drops in blood pressure can lead to fainting, with a possibility of injury. Moderate drops in blood pressure can cause confusion/inattention, delirium, and episodes of ataxia. Chronic orthostatic hypotension is associated with cerebral hypoperfusion that may accelerate the pathophysiology of dementia. [5]
How these symptoms affect the patient depends on to which organs or body parts blood supply is inhibited. Typical symptoms of Flammer syndrome are cold hands or feet, low blood pressure, occasional white and red patches on the face or neck, and migraine-like pain or a feeling of pressure behind the upper eyelid.

Neurogenic shock's presentation includes: [7] [8] - warm and pink skin - labored breathing - low blood pressure - dizziness - anxiety - history of trauma to head or upper spine. - if the injury is to the head or neck, hoarseness or difficulty swallowing may occur.
Blood pressure that is too low is called hypotension, pressure that is consistently too high is called hypertension, and normal pressure is called normotension. [9] Both hypertension and hypotension have many causes and may be of sudden onset or of long duration.
During their analysis, they split the participants into three groups — high, medium, and low blood pressure variation. They found that, overall, those in the high variability group had lower ...

The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3] Recovery from a reflex syncope episode happens without specific treatment. [2]
