Is 6 cm amniotic fluid low?

The sonographer will measure the largest pockets of amniotic fluid in four different sections of your uterus and add them together to see where you rate on the amniotic fluid index (AFI). A normal measure for the third trimester is between 5 and 25 centimeters (cm). A total of less than 5 cm is considered low.

What is the normal range of amniotic fluid index?

Usually, the normal value of amniotic fluid index varies from 50 mm to 250 mm (or 5 cm to 25 cm). Normal AFI varies from 80 mm to 180mm. An average AFI level is 80 mm to 140 mm when you are in your 20 weeks to 35 weeks of pregnancy. After 35 week, AFI levels usually begin to reduce.

What are the risks of too much amniotic fluid?

Too much amniotic fluid can cause the mother’s uterus to become overdistended and may lead to preterm labor or premature rupture of membranes (the amniotic sac). Hydramnios is also associated with birth defects in the fetus. When the amniotic sac ruptures, large amounts of fluid leaving the uterus may increase the risk of placental abruption
