ALL
SUCH MISHAPS CAUSED
BY POSTURAL
HYPOTENSION
Most of us have experienced sudden dizziness and vertigo when getting
up
very
rapidly from prolonged
squatting
-
in
fact, these are signs of
mild
"postural hypotension"
or
falling
of
the normal blood pressure due
to
insufficient blood being pumped
up
to
the
brain when getting
up
too
rapidly
from
a
squatting position.
Usually,
with normal health
and
regular exercises,
the
heart is able
to
compensate promptly
by
working
much harder
immediately when a
much
more
rapid blood
flow is
required
to
reach
the
brain.
However, for
those who are elderly, physically weak or
without
regular exercises,
the
heart becomes less capable. ln
that
case, these people would
have
to take note of this very well. Be sure to "take
it easy"
whenever they
are
getting
up.
Another well-defined
group
consists
of
those taking anti-hypertensive
drugs.
To
document the
possibility of postural hypotension, take
the
blood pressure both lying and standing.
lf
required, take the
"three
1/2 minute" step:
take 1/2
min
for
hand
and
leg exercises
whilst on
bed;
another ?
min
sitting
up
on
bed;the
last
1/2 min
with
legs
dangling
on
the
bed side.
Even
severe constipation requiring prolonged toilet
use
may also
cause
hypotension, especially
with
squatting
toilets.Faintinginsideatoiletcouldbeveryrisky'Those
elderly
having
frequency
at
night should take
extra
care
not
to drink too
much
fluid before retiring, otherwise
a
very full bladder
may
easily prompt
one
to get
up
far
too
quickly.
An old lady
had
thus died when she fell
down
the
bedside.
