If a woman has severe oligohydramnios near the time of delivery, her provider may suggest infusing salty water (saline solution) through the cervix into the uterus. This treatment, called amnioinfusion, may help reduce complications during labor and delivery and reduce the need for cesarean section. Some studies suggest that women with oligohydramnios can help increase their levels of amniotic fluid by drinking extra water. Also, many providers recommend decreasing physical activity or bed rest.
