|Whenever I stand up, I get black spots in front of my eyes
for a moment or two and feel dizzy. Is this normal?
Although fainting during pregnancy is more unusual than
you would expect, dizziness is extremely common. The reasons
for dizziness are varied.
In the beginning of the pregnancy, your system is struggling
to cope with the increased demands. Your body is producing
extra blood to meet these demands – but sometimes
the supply just can’t match the demand. Generally
if you take care of your diet and lifestyle (such as some
gentle exercise and enough rest) then this situation will
rectify itself. As the pregnancy advances, your uterus is
growing and its size may exert pressure on your blood vessels.
Again, this is not serious, just a sign to take good care
of yourself. You may also experience slight anaemia, which
your doctor will probably check for at every visit. The
demands of pregnancy mean that your iron supplies can easily
be depleted, and it may be worth asking your doctor to recommend

small regular meals which include a good portion of lean
protein, as this is a good way to regulate your blood sugar.
A stuffy environment is also a reason for dizziness. Just
be aware that you overheat easily, and move to a cooler
place if you feel too hot.
If the dizziness is persistent, then you should try to
get some extra blood to your brain. The easiest way to do
this is to lie down with your head lower than your feet
– for example, lie with a pillow under your feet and
not under your head. If you are not in a place where you
can lie down, the next best option is to kneel down on one
knee as though you were putting your shoe on. Do not forget
to mention your dizzy spells to your doctor at your next
