Many
of us do not need and he felt days, similar to dizziness or vertigo simple when
standing after lying down or after sitting for a long time ... so continue for a
few seconds .. The accompanying blurry vision and voice ringing in the ear ..
and other things less Ktnmal parties and others.
What is this
called? Is it a health problem call the
doctor? What
causes? And how can we avoid
it?
Orthostatic
hypotensionPostural
Hypotension
Definition:
Is
kind of a drop in blood pressure, which occurs when you do after a sitting
position or lie down so that it is in the form of dizziness and imbalance
sometimes up to fainting! It
may happen hypotension orthostatic anyone, especially adults age Vnspth those
over the age of 65 ranged 15% often comes hypotension orthostatic slightly and
continue for a few seconds or minutes, but sometimes it may be an indication of
a serious problem, especially when the problem recurs for long.In
mild cases may not need treatment, but must treat the cause of the most
difficult situations.Symptoms- Feeling dizzy or
dizziness after standing- Blurred
vision- General weakness-
Sometimes fainting- Visible- Headache- Lack of
concentration
Reasons
The
lying down or sitting for a long time leading to accumulation of blood in the
parts closest to the Earth's surface because of gravity, and when you do the
sudden delayed blood to reach the heart to pump to various body parts, including
the brain, it is expected here that fall blood pressure but there are mechanisms
physiological body prevent
this from happening, such as a reaction reflexive nervous fast through some
receptors Baroreceptors next cardiovascular and neck .. that lead to an
acceleration in the pumping of the heart (increase palpitations) and increase
the strength of contraction to increase the amount of blood pumped by the
Alanaqbadh per, as well as the secretion of hormones necessary the
constriction of blood vessels and thereby increase the resistance and elevated
blood pressure.
It
occurs orthostatic hypotension when there is any defect in these mechanisms, or
the existence of reflectors work .. as follows:
-
Decrease in blood volume due to lack of drinking fluids or losing heavily as
vomiting and diarrhea cases and sweating in cases of fever and excessive
exerciseAll
this can lead to the loss of large quantities of water in addition to sodium
salts than are covered person and even loss of small amounts of them .. may lead
to imbalance and fatigue and overwork .. In case of loss large including Vmanml
a so-called Hypovolemic shock any a
decrease in size and shock of the complications that threaten a person's life in
case of poor perfusion in the body, especially if severe and is not controlled
.. can lead to death within minutes or hours!
- DrugsA
lot of drugs lead to hypotension orthostatic and most important drugs to treat
high blood pressure and heart medications because they lead to the loss of large
amounts of fluid through the kidneys .. especially when high doses and in the
elderly, such as Beta blockers, and diuretics Diuretics and blockers calcium
Calcium channel blocker and ACEI and
nitroglycerin and also medications used to treat Parkinson's disease Parkinson's
disease
Also
taking medications that have an impact on the nervous system, and thus affect
the nerve sensors in arteries, Vtqll efficiency Lord has done it, such as
hypnotics Albarpittalah narcotics, and alcohol intake.
-
Heart problemsSuch
as the problems that lead to low blood pressure .. such as low rapid heartbeat
(bradycardia) and problems of the heart valves and heart failure .. all can lead
to orthostatic hypotension to insufficient blood within the circulatory
system.
- DiabetesWhen
they are not diabetic control .. lead to increased urination .. and thus the
loss of fluids and also affects diabetes and nerve functions in the body,
including those that transmit nerve signals to control blood
pressure.
-
Problems in the nervous system, such as: Parkinson's diseasemultiple system
atrophy (Shy-Drager syndromeamyloidosis
that affect the way the body's regulation of blood pressure
also.
Risk Factors
-
Age: Most cases occur more on the age of 65 years .. because with increasing age
.. تتباطئ
receptors Baroreceptors ability to regulate blood pressure, and is less than the
ability of the heart to increase the speed of pulses to compensate for the drop
of blood.
- Drugs: such as
those mentioned above.
-
Some diseases: such as Parkinson's disease and some heart disease as previously
mentioned.
-
Exposure to high temperature: leading to excessive sweating and thus the loss of
a large amount of fluid.
-
Lying down or standing for a long time: like lying in bed for a long time
because of illness or surgery .. This leads to a general weakness in the body
has been infected person orthostatic fall in blood pressure for a temporary
period.
-
Sit his بقدمين crossed for a long time: whether the man on the other man's knee
... knee or ankle on the other man - as men usually sits - this leads to
pressure on the blood vessels and thus encourages collect blood in the
feet.
-
Pregnancy: As a result of the expansion of circulation quickly to pregnant ..
leading to low blood pressure .. has become significant enough to drop suddenly
when you do.
When should you see a
doctor??
Most
cases are minor and temporary due to lack of drinking fluids or low blood sugar,
or exposure to the sun or heat for a long time.But
if the problem persists for a long time without one of these reasons. Might be
an indication of a problem .. then tried to record the times when I felt so and
what you were doing at the time. Then see a specialist
doctor.
Complications
Most
cases do not lead to complications .. but just because they harass a person no
moreBut
may sometimes lead to serious complications in advanced cases, such
as:
Fall: result
fainting .. and the consequent risk ofStroke:
increases the likelihood of their occurrence.Dementia:
Some research has shown that modern orthostatic hypotension may lead to chronic
brain damage as a result of ischemia and subsequent incidence of early dementia
and brain problems.
Diagnostic
tests and
The
aim of the tests is to determine the cause of the problem to reach the right
solution
-
Measuring blood pressure: and compared during sitting and standing five
minutes-
Blood tests: and give you a general idea about the health of the body .. such as
the level of sugar in the blood, and the presence of anemia that may lead to
lower blood pressureECG ECGEchocardiogramAnd
others according to what the doctor deems appropriate.
Treatment
And
depends on the underlying cause of the problem, but overall when you feel such
symptoms .. you lie down and stretch it straight so that the level of the feet
higher than the level of the head.
If
the cause of the problem is drugs .. Either reduce the dose used, or replace the
medicine with another.
And
there are some treatments that may be useful, such as: change of lifestyle:
drinking larger amounts of liquids, avoid drinking alcohol, avoid exposure to
heat for a long timeAnd
also avoid sudden stand, but try to do gradually after lying
downAvoid standing
for a long time without movement.There
are some exercises to strengthen the muscles of the man .. Your doctor may
advise you to increase the amount of salt in food are few if you do not suffer
from high blood pressure.
Compression
stockings: which are commonly used in the case of varicose veins .. possible be
useful in preventing the blood pool FBI feet and thereby relieve
symptoms.
Medicines:
There are some drugs that may be useful in the treatment of the problem by
raising blood pressure.
