Orthostatic hypotension means excessive
decrease in blood pressure which may occur when a person stands up,
resulting in reduced blood flow to the brain and dizziness or fainting.
Controlling blood pressure through blood pressure medication is easy. It
is more prevalent among older people. Natural blood pressure herbal
remedy is a good way to lessen the effects of high blood pressure.
It is not a specific disease but an inability to compensate
quickly for changes in blood pressure. When a person stands up suddenly,
gravity causes the blood to pool in the veins of the legs and lower
body. As a result, the amount of blood returned to the heart and pumped
out by the heart is reduced, and blood pressure falls. In case of
younger people, the body quickly responds to a
decrease in blood pressure: the heart beats faster and more forcefully to increase its
output of blood and the arterioles constrict to increase resistance to
blood flow. If these compensatory mechanisms malfunction or function too
slowly, both of which commonly occur in older people, orthostatic
hypotension may occur. For further information read The Basics Of Low Blood Pressure
Other specific causes of
orthostatic hypotension are, the heart's ability to increase its output
enough when a person stands, abnormal heart rate and blood pressure and
heart valve disorders, decrease of blood volume, drugs such as
diuretics, which are used to treat high blood pressure, bleeding and an
excessive loss of fluid due to severe vomiting, diarrhea, excessive
sweating, or excessive urination. Among older people, dehydration during
an illness is a common cause of low blood volume leading to orthostatic
hypotension.
More causes of orthostatic hypotension are noticed
by dilating arterioles and veins. Drugs that dilate arterioles
(vasodilators) can cause orthostatic hypotension. They include nitrates,
calcium channel blockers, angiotensin, alcohol, and antidepressants.
Disorders such as diabetes, amyloidosis, and spinal cord injuries may
damage the nerves that regulate blood vessel diameter. Fatigue,
exercise, or consumption of a heavy meal can contribute to orthostatic
hypotension. To cure high blood pressure and orthostatic hypotension,
you can check the blood pressure units on a regular basis through blood
pressure monitor like samsung blood pressure monitor and thus keep it
under control.
