Mild cases of polyhydramnios may go away on their own. Severe cases may require treatment. Polyhydramnios (pol-e-hi-DRAM-nee-os) is the excessive accumulation of amniotic fluid — the fluid that surrounds the baby in the uterus during pregnancy. Polyhydramnios occurs in about 1 to 2 percent of pregnancies.

The structure of the amniote egg. Inside the egg are a series of fluid-filled membranes which permit the embryo to survive: the amnion, allantois, yolk sac, and chorion. Surrounding and protecting the embryo is the amnion, filled with amniotic fluid, and providing the embryo with a stable fluid environment.

Low amniotic fluid (oligohydramnios) is a condition in which the amniotic fluid measures lower than expected for a baby's gestational age. No treatment has been proved effective long term. But short-term improvement of amniotic fluid is possible and might be done in certain circumstances.

Your doctor can measure your amniotic fluid levels using an ultrasound. There are two calculations on ways to measure, known as the amniotic fluid index (AFI) or the maximum vertical pocket (MPV). Doctors consider your fluid levels to be low if your AFI is less than 5 centimeters (cm) or your MPV is less than 2 cm.
