Causes of polyhydramnios. 1  Polyhydramnios can sometimes mean that there is a birth defect or a medical problem. 2  Birth defects that affect the baby's ability to swallow and process amniotic fluid may cause polyhydramnios. Most of these birth defects are rare, but it is important to perform a detailed ultrasound to make sure there is no evidence of these conditions.
Polyhydramnios occurs when too much amniotic fluid builds up during pregnancy. It is also called amniotic fluid disorder, or hydramnios. Amniotic fluid is the liquid that surrounds the baby in the womb (uterus). It comes from the baby's kidneys, and it goes into the uterus from the baby's urine.
