Polyhydramnios and oligoamnios
We call polyhydramnios to the excess of amniotic fluid. Sometimes, this excess will be normal: when the baby is big or when the pregnancy is multiple. But this can also be a consequence of a disease of the mother like diabetes or a disease of the baby like the one called congenital malformations. Oligoamnios are the opposite, the diminution of the amount of amniotic fluid.
It is advisable to rest in order to avoid a premature childbirth. If there are respiratory difficulties, drainage off the excess of fluid by means of a puncture with an intra-amniotic catheter can be done.
