The condition can also cause complications for the fetus, including anatomical problems, malposition, and, in severe cases, death. Treatment aims to remove excess amniotic fluid"
"Most women with polyhydramnios will not have any significant problems during their pregnancy and will have a healthy baby. But there is a slightly increased risk of pregnancy and birth complications, such as: giving birth prematurely (before 37 weeks) your waters breaking early."
