Polyhydramnios

Polyhydramnios is a condition in which there is an abnormally high amount of amniotic fluid present in the amniotic sac. It is caused by fetal anomalies like esophageal atresia and anencephaly that result in an inability to swallow the fluid; maternal diabetes; fetal anemia, or multiple gestations. It is diagnosed through ultrasound during pregnancy, and symptoms include a high fundal height not corresponding to the gestational age, and difficulty palpating the fetal parts. Treatment is determined by the cause, gestational age, and severity; and may include expectant management or amniocentesis.
