And can it be dangerous to you and
your baby?
In the past, placenta calcification was
only identified after the birth when the placenta (also called the afterbirth)
was physically examined by the doctor or midwife. Small white calcium deposits
like little hard stones were seen and felt. This was not thought to be a
problem. It was said that the placenta was simply ageing – a normal phenomenon
when baby is due or late. Other signs of an overdue baby are long fingernails,
little vernix (Nature’s barrier cream to protect baby’s skin in the amniotic
fluid) and dry, peeling skin.
With modern technology and advanced 3D
sonar graphics, placenta calcification can be identified before the birth. If
calcification is suspected when baby is due, this is not a problem, but
calcification in early pregnancy could mean that the placenta is ageing before
its time, and the baby could be compromised. For most women with placenta
calcification, careful monitoring of the baby’s growth is all that is needed.

If calcification is associated with other
medical problems such as hypertension (high blood pressure), diabetes or kidney
problems, medical intervention may be necessary. Luckily these are rare
Where does the calcium come from and
what can I do to prevent this?
Calcium is an important part of the diet
and is sourced mainly from milk and cheese but also from eggs, fruit and
vegetables. Its absorption from the intestines is dependent on vitamin D that
comes from ultraviolet sunlight and also fish liver oils, egg yolk and
fortified milk. Calcium is needed by the body for bone and tooth maintenance,
blood clotting, nerve and muscle function and a normal heartbeat.
As a pregnant woman, you need extra calcium
– 1200mg daily for your needs and for bone development of your unborn baby. If
you have too little calcium, your bones will supply these needs for the baby
and put you at risk for osteoporosis (brittle bones) in later life.

Taking too much calcium does not seem to
affect the baby, but for you as the mother, it could cause painful kidney
stones.
There seems to be some concern about
antacids for heartburn during pregnancy that contain high doses of calcium.
Most chewable antacids are made from calcium carbonate and give fast relief.
Sucking the occasional antacid may be harmless, but if you suffer with severe
heartburn and you are taking too many antacids, you could also be taking in too
much calcium.
Preventing placenta calcification
If your pregnancy is 37 weeks or more,
there is no need to worry.
Make sure you are taking the right amount
of daily calcium. Check your antenatal multivitamins and calcium
supplementation with your pharmacist.
Remember that calcium also comes from your
diet – so don’t overdose with supplements.
Before taking antacids for heartburn, speak
to your pharmacist or healthcare provider.
You are more at risk of calcification if
your blood pressure is too high or you are a diabetic.
How does placenta calcification affect
my unborn baby?
Placenta calcification from 37 weeks is
considered normal and is not a reason to induce labor or to have a C-section.
Women with this condition may simply need to see their doctor more often to
check their baby’s growth.
Placenta calcification before 37 weeks
becomes more dangerous for the baby. The younger the baby when calcification
happens, the more severe the condition.

Risks of placental calcification
An ageing placenta does not work as well as
it should, and this could mean not getting enough oxygen and nutrients to the
baby. Deposits of calcium in the placenta could cause parts of the placenta to
die or be replaced with fibrous tissue which is unhelpful tissue in the
placenta.
Calcium deposits could also increase the
risk of blood clots in the placenta. They could harden blood vessels in the
placenta and slow down the blood flow to the baby. Fortunately, complications
due to placenta calcification are practically zero, and in most cases, it’s not
dangerous for the baby.
Diagnosing placenta calcification
A pelvic sonographer of the placenta is the
only way to diagnose this condition. Calcification is sometimes picked up
during a routine scan. If the woman is close to her delivery date, this means
that labor is very likely to begin over the next few weeks. If the baby is
younger than 37 weeks, it may be slightly riskier, but rarely is it dangerous
for the baby.
