Causes Of Orthostatic Hypotension

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.

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.
