In this condition, there is too
much amniotic fluid around your baby during pregnancy. It happens in about 1 in 100
pregnancies. It’s also called polyhydramnios.
Your baby needs amniotic fluid to
grow. This watery fluid is inside the amniotic sac (membrane). It’s sometimes called
bag of waters. Your baby stays in this fluid for all of pregnancy. It helps to cushion
and protect your baby. Amniotic fluid also helps your baby’s lungs, kidneys, and
gastrointestinal tract grow.
The fluid is made by your baby’s
lungs and kidneys. Your baby swallows the fluid and passes it out as urine. The waste
taken away through your placenta.
Pregnant women normally have about
1 pint to 1 quart (500 to 1,000 ml) of amniotic fluid. Too much or too little amniotic
fluid can cause problems. These issues can affect how your baby develops. They can
cause pregnancy complications. Or the amount of amniotic fluid may be a sign of another
This condition may happen for
several reasons. Either too much fluid is made or there’s a problem with the fluid
taken away. Or both of these things may be happening. Hydramnios may be caused by
diabetes in the mother.
It can also be caused by problems
with the developing baby. These can include:
- Digestive problems that block
- Problems with swallowing that may be
due to a central nervous system problem or chromosome issues
- Twin-to-twin transfusion syndrome, a
condition where identical twins share a placenta
- Heart failure
Symptoms can occur a bit
differently in each pregnancy. They can include:
- Fast growth of your uterus
- Stomach discomfort
- Uterus that is larger than normal for
how far along you are in pregnancy
- Labor pains (contractions)
The symptoms of this health problem
may be like symptoms of other conditions. See your healthcare provider for a
Your healthcare provider will look
at your health history. He or she will also give you an exam. A healthcare provider
spot this condition on an ultrasound during pregnancy. He or she will measure pockets
fluid to check the amount. In some cases, an ultrasound can help find the cause of
hydramnios. These can include a multiple pregnancy or a birth defect.
The goal of treatment is to keep
you pregnant for as long as it’s safe. Treatment may also make you more comfortable.
Treatment will depend on your
symptoms, pregnancy, and general health. It will also depend on how severe the condition
is. Treatment may include:
Closely watching the amount of amniotic
fluid you have.
Your healthcare provider will check this at your visits.
Medicine. This can reduce how much
urine your baby makes. This can lower the amount of fluid.
Removing some of the amniotic fluid.
This is done by inserting a needle through your uterus and into the amniotic sac.
This is called amnioreduction with amniocentesis. You may need to have this done more
Delivery. If problems are too risky
for you or your baby, you may need to deliver your baby early.
Too much amniotic fluid can cause
your uterus to become too large. This may lead to preterm labor. Or the amniotic sac
break too early.
This condition is also linked with
birth defects. When the sac breaks, large amounts of fluid leave the uterus. This
cause the placenta to detach from your uterus too early (placental abruption). It
also cause the umbilical cord to fall into your vagina (umbilical cord prolapse).
