Effects of age on blood pressure Alternative names Return to top Hypotension; Low blood pressure Definition Return to top Low blood pressure is an abnormal condition where a person's blood pressure (the pressure of the blood against the walls of the blood vessels during and after each beat of the heart) is much lower than usual, which can cause symptoms such as dizziness or lightheadedness. Considerations Return to top When the blood pressure is too low, there is inadequate blood flow to the heart, brain, and other vital organs. A blood pressure level that is borderline low for one person may be normal for another. The most important factor is how the blood pressure changes from the normal condition. Most normal blood pressures fall in the range of 90/60 mm Hg to 130/80 mm Hg, but a significant change, even as little as 20 mm Hg, can cause problems for some people. Common Causes Return to top Low blood pressure is commonly caused by drugs such as the following
  • Medications used for surgery Anti-anxiety agents Treatment for high blood pressure Diuretics Heart medicines Some antidepressants Narcotic analgesics Alcohol
Other causes of low blood pressure include the following:

Orthostatic hypotension is a sudden fall in blood pressure that occurs when a person assumes a standing position. It may be caused by hypovolemia (a decreased amount of blood in the body), resulting from the excessive use of diuretics, vasodilators, or other types of drugs, dehydration, or prolonged bed rest. The disorder may be associated with Addison's disease, atherosclerosis (build-up of fatty deposits in the arteries), diabetes, and certain neurological disorders including Shy-Drager syndrome and other dysautonomias. Symptoms, which generally occur after sudden standing, include dizziness, lightheadedness, blurred vision, and syncope (temporary loss of consciousness).

Timothy C. Hain, MD. Please read our Return to Index Page last modified: September 4, 2005 Orthostasis means upright posture, and hypotension means low blood pressure. Thus, orthostatic hypotension consists of symptoms of dizziness, faintness or lightheadedness which appear only on standing, and which are caused by low blood pressure. Only rarely is spinning vertigo caused by orthostasis. Symptoms that often accompany orthostatic hypotension include chest pain, trouble holding the urine, impotence, and dry skin from loss of sweating.
What Causes Orthostatic Hypotension ?
Blood pressure is maintained by a combination of several things. The heart is the central pump, and a weak or irregular heart can cause orthostasis. Conditions such as arrhythmia, heart failure, deconditioning, and pregnancy are examples where the heart may not be up to the task of providing an adequate blood pressure. The heart pumps blood, and if there is too little blood volume (anemia, dehydration, dialysis), the pressure drops. The blood vessels in the body also can squeeze (constrict) to raise blood pressure, and if this action is paralyzed, blood pressure may fall. Numerous medications affect blood vessels including most of the medications used for blood pressure, and many of the medications used in psychiatry and for anginal heart pain. Heat, such as a hot shower or from a fever can also dilate blood vessels and cause orthostasis. The nervous system senses and responds to regulate blood pressure. If something is wrong in this control system, blood pressure may fluctuate.

O rthostatic hypotension, which is a physical finding, not a disease, may be symptomatic or asymptomatic. The American Autonomic Society (AAS) and the American Academy of Neurology (AAN) define orthostatic hypotension as a systolic blood pressure decrease of at least 20 mm Hg or a diastolic blood pressure decrease of at least 10 mm Hg within three minutes of standing up. [Evidence level C, consensus/expert guidelines] The AAS and AAN also provide a tilt-table definition. This determination has limited usefulness for the approach outlined in this article and appears to have a high rate of false-positive results. Orthostatic hypotension has been observed in all age groups, but it occurs more frequently in the elderly, especially in persons who are sick and frail.

A sudden brief loss of consciousness, with loss of postural tone.
Etiology and Pathophysiology
Bradyarrhythmias (especially those with abrupt onset) can cause syncope. These include the sick sinus syndrome, with or without tachyarrhythmias, and high-grade atrioventricular block. Although bradyarrhythmias occur at all ages, they are most frequent in the elderly and are usually due to ischemia or fibrosis of the conduction system. Digitalis, -blockers (including ophthalmic -blockers), Ca blockers, and other drugs may also cause bradyarrhythmias. Supraventricular or ventricular tachyarrhythmias that cause syncope may be related to ischemia, heart failure, drug toxicity (quinidine syncope is the best known), electrolyte abnormalities, preexcitation, and other disorders. Syncope with chest pain of myocardial ischemia is usually related to arrhythmia or heart block but rarely may reflect substantial ischemic ventricular dysfunction with a reduced cardiac output. Syncope can be due to atrioventricular block in acute inferior MI. Many other mechanisms, often in combination, may limit cardiac output, such as a decrease in systemic BP due to peripheral vasodilation, decreased venous return to the heart, hypovolemia, and cardiac outflow obstruction. Diminished cerebral perfusion may also be caused by cerebral vasoconstriction, eg, induced by hypocapnia.

Postprandial hypotension occurs in up to one third of older people but virtually never occurs in younger people. It is more likely to occur in people who have high blood pressure or disorders that impair the brain centers controlling the autonomic nervous system (which regulates internal body processes). Examples of such disorders are Parkinson's disease, multiple systems atrophy (Shy-Drager syndrome), and diabetes. The intestines require a large amount of blood for digestion. When blood flows to the intestines after a meal, the heart rate increases and blood vessels in other parts of the body constrict to help maintain blood pressure. However, in some older people, such mechanisms may be inadequate. Blood flows normally to the intestines, but the heart rate does not increase adequately and blood vessels do not constrict enough to maintain blood pressure. As a result, blood pressure falls.

From Wikipedia, the free encyclopedia.
In physiology and medicine hypotension refers to an abnormally low blood pressure . It is often associated with shock , though not necessarily indicative of it.
Orthostatic hypotension is a common cause of low blood pressure , resulting from a sudden change in body position. Reduced blood volume, called hypovolemia , can also cause hypotension and often results from the use of diuretics or vasodilators such as nitric oxide or furosemide . It has been recorded as a side-effect of certain forms of anesthesia , such as curare , in which event it is often treated by the anesthesiologist . Another albeit rare form, is "post prandial hypotension", which occurs 30-75 minutes after eating. It is not well understood. edit
For most individuals, a healthy blood pressure lies between 90/60 mmHg to 130/80 mmHg. A small drop in blood pressure, even as little as 20 mmHg, can result in transient hypotension.
