Amniotic fluid present in the amniotic sac provides a cushion to the baby in the womb protecting it from injuries. Polyhydramnios is a medical condition in which excessive accumulation of fluid takes place in the amniotic sac.
Polyhydramnios is not a common condition and occurs in around one percent of pregnancies. The cases are mostly mild and result due to a gradual build-up of amniotic fluid during the second half of a pregnancy. This condition is diagnosed when the amniotic volume reaches two litres or more. Acute polyhydramnios is common if you’re having a multiple pregnancy i.e., a pregnancy with more than one baby. more “Polyhydramnios – Things You Need To Know”
