How Much Is Too Much Amniotic Fluid?

The range depends on how far along you are in your pregnancy, as the fluid levels will increase up to your third trimester, then decrease. As a rule of thumb, polyhydramnios is usually diagnosed with an AFI over 24 or a big pocket of fluid on the ultrasound of over 8 cm.

What are the signs of too much amniotic fluid?

Women with polyhydramnios often have no signs or symptoms. When symptoms do occur, they can include difficulty breathing, premature contractions, or, if polyhydramnios is severe, pain in the abdomen. When the uterus is larger than expected for the fetus's age, this could indicate that there is too much amniotic fluid.

How much amniotic fluid is normal?

A normal amniotic fluid index is 5 cm to 25 cm using the standard assessment method. Less than 5 cm is considered oligohydramnios, and greater than 25 cm is considered polyhydramnios.
