It simply means you have a low blood pressure, and that blood flow to your brains has
reduces, this is why your vision is lost, don’t panic, you might probably have a low blood pressure,
a condition known as postural
hypotension. A drop in
blood pressure : an individual blood pressure goes down when he changes
position and there is no enough blood flow to the brain. Another cause may be
TIA, meaning Temporary Ischemic Attack, a condition very similar to stroke but
just temporal, other common causes are:
·
Blockages in your blood vessels, plaque or any piece of debris in your
blood vessels can cause it.
·
Dehydration due to over-exposure to the sun,
chronic diarrhea or vomiting can also cause this.
·
C-section: when you have C- section, you may be
bleeding internally and or have lost plenty of blood in the surgery
·
Anemia: lack of enough oxygen
to the brain can cause it,
·
High blood pressure, you may have high
blood pressure, when you have high blood pressure the pulse rate is high and no enough blood to
refill it as normally , you may have a black vision.
The best solution to the above
is to see your doctor but the most common condition is postural hypotension
meaning a drop in blood pressure when you suddenly changes position, this is
how it happens, when you lie down, the blood in the lower part of your body usually
legs and trunks will move to your chest,
when you suddenly stand up blood from your chest will then feel your
legs and trunks and therefore less blood is available to feel your heart and
head. This will cause your eye vision to go. Normally the veins in your less will
quickly pump the blood to feel your hearth but for person having a low
blood pressure it happen slowly and you
will have back vision.
