Oligohydramnios occurs when the volume of amniotic fluid is decreased during gestation. The diagnosis is ultrasound, measuring the amount of amniotic fluid by ultrasound.
We can divide the causes of Oligohydramnios into three main groups:
- Fetal causes: restricted intrauterine growth (RIC), chronologically prolonged gestation (CPG), fetal infection or alterations of the fetal urinary tract.
- Placental-membrane causes: premature rupture of membranes (PROM) accounts for most cases.
- Maternal causes: maternal medication.
Depending on the cause of Oligohydramnios and the time of pregnancy, your obstetrician will give you recommendations.
