You'll usually be advised to give birth in hospital. It is not usually a sign of anything serious, but you'll probably have some extra check-ups. Too much amniotic fluid is normally spotted during a check-up in the later stages of pregnancy. Amniotic fluid is the fluid that surrounds your baby in the womb. If the fluid level gets very low, though, there's some risk to your baby because the umbilical cord can become squeezed, preventing your baby from getting enough food and oxygen.Polyhydramnios is where there is too much amniotic fluid around the baby during pregnancy. Most cases of oligohydramnios in the third trimester won't result in any complications for your baby. Is low amniotic fluid dangerous for my baby? If his kidneys aren't there or aren't developing properly or his urinary tract is blocked, for example, your baby won't produce enough urine to maintain the level of amniotic fluid. If you're found to have low levels of amniotic fluid in your first or second trimester, it may mean that your baby has a birth defect. ![]() Being two weeks or more past your due date can put you at risk for oligohydramnios.

If the placenta doesn't supply enough blood and nutrients to your baby, he will stop producing urine. She may also be on the lookout for it if you've previously had a baby whose growth was restricted or if you have certain pregnancy complications (see maternal complications, below), or if you're past your due date.Ī problem with your placenta, such as a partial abruption, in which the placenta peels away from the inner wall of the uterus, can lead to low levels of amniotic fluid. Your practitioner may suspect this problem if you're leaking fluid, measuring small for your stage of pregnancy, or not feeling your baby move very much.

Early in the second trimester, your baby starts to swallow the fluid, pass it through their kidneys, and excrete it as urine, which they then swallow again, recycling the full volume of amniotic fluid every few hours.
