Clinical Classification

Clinical Information

  • Hypotension

    abnormally low blood pressure that can result in inadequate blood flow to the brain and other vital organs. common symptom is dizziness but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.
  • Hypotension, Controlled

    procedure in which arterial blood pressure is intentionally reduced in order to control blood loss during surgery. this procedure is performed either pharmacologically or by pre-surgical removal of blood.
  • Hypotension, Orthostatic

    a significant drop in blood pressure after assuming a standing position. orthostatic hypotension is a finding, and defined as a 20-mm hg decrease in systolic pressure or a 10-mm hg decrease in diastolic pressure 3 minutes after the person has risen from supine to standing. symptoms generally include dizziness, blurred vision, and syncope.
  • Intracranial Hypotension

    reduction of cerebrospinal fluid pressure characterized clinically by orthostatic headache and occasionally by an abducens nerve palsy; hearing loss; nausea; neck stiffness, and other symptoms. this condition may be spontaneous or secondary to cerebrospinal fluid leak; spinal puncture; neurosurgical procedures; dehydration; uremia; trauma (see also craniocerebral trauma); and other processes. chronic hypotension may be associated with subdural hematomas (see hematoma, subdural) or hygromas. (from semin neurol 1996 mar;16(1):5-10; adams et al., principles of neurology, 6th ed, pp637-8)
  • Ocular Hypotension

    abnormally low intraocular pressure often related to chronic inflammation (uveitis).
  • Post-Exercise Hypotension

    transient reduction in blood pressure levels immediately after exercises that lasts 2-12 hours. the reduction varies but is typically 5-20 mm hg when compared to pre-exercise levels. it exists both in normotensive and hypertensive individuals and may play a role in excercise related physiologic adaptation.
  • Shy-Drager Syndrome

    a progressive neurodegenerative condition of the central and autonomic nervous systems characterized by atrophy of the preganglionic lateral horn neurons of the thoracic spinal cord. this disease is generally considered a clinical variant of multiple system atrophy. affected individuals present in the fifth or sixth decade with orthostasis and bladder dysfunction; and later develop fecal incontinence; anhidrosis; ataxia; impotence; and alterations of tone suggestive of basal ganglia dysfunction. (from adams et al., principles of neurology, 6th ed, p536)
  • Adaptation, Physiological

    the non-genetic biological changes of an organism in response to challenges in its environment.

Patient Education


Autonomic Nervous System Disorders

Your autonomic nervous system is the part of your nervous system that controls involuntary actions, such as the beating of your heart and the widening or narrowing of your blood vessels. When something goes wrong in this system, it can cause serious problems, including:

  • Blood pressure problems
  • Heart problems
  • Trouble with breathing and swallowing
  • Erectile dysfunction in men

Autonomic nervous system disorders can occur alone or as the result of another disease, such as Parkinson's disease, alcoholism and diabetes. Problems can affect either part of the system, as in complex regional pain syndromes, or all of the system. Some types are temporary, but many worsen over time. When they affect your breathing or heart function, these disorders can be life-threatening.

Some autonomic nervous system disorders get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms.

Orthostatic hypotension

Orthostatic hypotension is a drop in blood pressure that occurs when moving from a laying down (supine) position to a standing (upright) position. The word "orthostasis" means to stand up, so the condition is defined as low blood pressure (hypotension) that occurs upon standing.

When standing up, gravity moves blood from the upper body to the lower limbs. As a result, there is a temporary reduction in the amount of blood in the upper body for the heart to pump (cardiac output), which decreases blood pressure. Normally, the body quickly counteracts the force of gravity and maintains stable blood pressure and blood flow. In most people, this transient drop in blood pressure goes unnoticed. However, this transient orthostatic hypotension can cause lightheadedness that may result in falls and injury, particularly in older adults.

The body has difficulty achieving stable blood pressure in people with orthostatic hypotension, resulting in a prolonged drop in blood pressure that occurs within minutes after moving from laying down to standing. The vast majority of people with orthostatic hypotension do not experience symptoms related to the condition; it may be detected incidentally during routine medical testing. When measuring blood pressure, orthostatic hypotension is defined as a decrease in blood pressure by at least 20mmHg systolic or 10mmHg diastolic within 3 minutes of standing.

When signs and symptoms of orthostatic hypotension do occur, they are usually the result of a reduction in blood flow (hypoperfusion) to tissues, particularly the brain. Affected individuals may have fatigue, confusion, dizziness, blurred vision, or fainting episodes (syncope). Less frequently, affected individuals can experience muscle pain in the neck and shoulders (known as "coat hanger pain"), lower back pain, or weakness. During an episode of orthostatic hypotension, symptoms are often increased in severity by physical activity, warm temperatures, eating large meals, or standing for long periods of time.

In people with orthostatic hypotension, hypoperfusion to other organs contributes to an increased risk of life-threatening health problems, including heart attack or heart failure, a heart rhythm abnormality called atrial fibrillation, stroke, or chronic kidney failure. Additionally, affected individuals may get injured from falls during fainting episodes.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
