WHY DO I FAINT?
The doctor wanted to check the
pressure in my eyes, a procedure that required him to touch my eyeball with an
instrument. I knew what was going to happen. It always does. It is the same
when a nurse uses a needle to extract blood. Sometimes just talking about
injuries has the same effect. –I faint.
According to a British report
some 3 percent of us often faint when we are in one of the aforementioned
specific situations. If you are a fellow sufferer, you may have tried in vain
to stop yourself from fainting. You might have tried walking to the bathroom to
avoid fainting in public. But that is not a good idea. You might faint suddenly
on the way and injure yourself. After experiencing this reaction so many times.
I decided to find out what causes it.
After talking to a handful of
doctor and checking a few books. I found that such episode is called a
VASOVAGAL reaction. “Vasovagal” refers to the action upon the blood vessels of
a long nerve called the VAGUS NERVE. The latin word vagus means “wandering.” It
is thought to be a malfunction of a body system that is meant to regulate blood
circulation, such as when you change position from sitting to standing.
In certain circumstances, which
may include seeing blood or having your eyes examined, your involuntary nervous
system behaves as if you were lying down, when actually you are sitting or
standing up.
At first, your heart usually
races because of anxiety. Then your pulse rate slows precipitously and blood
vessels to your legs dilate, or widen. As a result, the blood supply increases
to your legs and lessens to your head. Your brain runs short of oxygen, and you
faint. How can you prevent this from happening?
You might look away when your
blood is being drawn, or you could lie down during the procedure. As mentioned,
when a vasovagal reaction is about to begin, you can often recognize the
warning signs. So there is usually time to take action before you faint. Many
doctors recommend that you lie down and prop your legs up against a chair or a
wall. This prevents your blood from draining into your legs, and thus you may
be able to prevent the reaction from running its full course. Within just a few
minutes, you will probably feel better.
If this information helps you as
it has me, you will be able to recognize the signs of an approaching vasovagal
reaction. Then you can take prompt action and stop it before it happens.
DOG’S ABILITY TO
DETECT FIT
Some dogs that have been household pets for
more than a year can foresee epileptic attacks in the children with whom they
live. Researchers reached this conclusion after carrying out a study of 45
families.
Several parents with epileptic
children noticed that prior to an attack; their dog began to behave in a “peculiar
way.” It would force the young one to sit down or would lean against the
child’s side so that if he fell, the dog would break his fall.
