Treatment for Oligohydramnios Amnioin fusion Fetal swallowing, which occurs physiologically, reduces the amount of fluid, and an absence of swallowing or a blockage of the fetus’s gastrointestinal tract can lead to polyhydramnios. However, because the amniotic fluid is primarily fetal urine in the latter half of the pregnancy, the absence of fetal urine production or a blockage in the fetus’s urinary tract can also result in oligohydramnios. The rupture of the membranes is the most common cause of oligohydramnios. Too little fluid for long periods may cause abnormal or incomplete development of the lungs called pulmonary hypoplasia. Renal agenesis, cystic kidneys, and bladder outlet obstructions are common. In the latter two-thirds of pregnancy, any condition that interferes with fetal urine production can lead to oligohydramnios. The mother has chronic high blood pressure or is using certain medications, such as ACE inhibitorsĪn inadequate volume of amniotic fluid, oligohydramnios, results in poor development of the lung tissue and can lead to fetal death.The placenta is separating from the uterine wall prematurely (placental abruption).The baby is having kidney or urinary tract problems.The baby has intrauterine growth restriction (IUGR) Placental insufficiency and fetal growth restriction.If the amount of fluid is low, it may be an indication that: Amniotic fluid volume cushions the fetus from physical trauma permits fetal lung growth and provides a barrier against infection. It also keeps some space between the baby, the umbilical cord, and the uterine wall, so that the cord doesn’t become compressed.īecause the amniotic fluid typically reflects the amount of fetus urine production, it’s used as a measure of the baby’s health and development. OligohydramniosĪmniotic fluid cushions the baby from outside stress and gives the baby enough room to move and grow inside the womb. What results is a set of possible risks or complications known as oligohydramnios (OH-lee-go-hy-DRAM-nee-os) and polyhydramnios (pol-ee-hy-DRAM-nee-os). Occasionally, a pregnancy can produce either too little or too much amniotic fluid, which is the fluid that surrounds the baby.
