Editing Polyhydramnios (section)

==Diagnosis==
There are several pathologic conditions that can predispose a pregnancy to polyhydramnios. These include a maternal history of [[diabetes mellitus]], [[Rh incompatibility]] between the fetus and mother, intrauterine infection, and [[multiple birth|multiple pregnancies]].

During the pregnancy, certain clinical signs may suggest polyhydramnios. In the mother, the physician may observe increased abdominal size out of proportion for her weight gain and gestation age, uterine size that outpaces gestational age, shiny skin with stria (seen mostly in severe polyhydramnios), dyspnea, and chest heaviness. When examining the fetus, faint fetal heart sounds are also an important clinical sign of this condition.
