A condition in which the amnion surrounding the fetus contains too little amniotic fluid.
A condition of having too little amniotic fluid during a pregnancy.
An abnormally small amount of amniotic fluid (the fluid that surrounds the fetus in the uterus during pregnancy). Mild oligohydramnios is usually not a serious problem but severe oligohydramnios often signals the presence of an abnormality. Oligohydramnios in early pregnancy may result in a miscarriage; late in pregnancy, it can cause birth defects or the death of the fetus. If oligohydramnios is suspected, the doctor will want to diagnose the underlying problem and treat it. If the pregnancy is advanced beyond the 37th week, the doctor may induce labor.
A condition in which the amount of amniotic fluid bathing a fetus during pregnancy is abnormally small. The developing infant may consequently be vulnerable, for example if the mother falls.
An abnormally small amount of amniotic fluid. It is a rare condition in which the volume of amniotic fluid during the third trimester is less than 300 ml. Insufficient fluid surrounding the fetus increases the potential for cord compression, fetal hypoxia, fetal malformation, perinatal demise, and dysfunctional and prolonged labor. Although the etiology is unknown, the disorder is associated with amniotic fluid leakage, placental insufficiency, post maturity, intrauterine growth retardation, and major congenital abnormalities of the fetal kidney or lungs.
A situation where there is an inadequate quantity of amniotic fluid enveloping a fetus within the uterus.
Amniotic fluid is generated partially by the placenta, and predominantly through the urine of the fetus. Oligohydramnios might arise from improper placental function, as observed in severe pre-eclampsia, or due to fetal kidney or bladder abnormalities. Diminished amniotic fluid levels could also stem from leakage resulting from premature rupture of the amniotic membranes.
Oligohydramnios can be suspected when the size of the woman’s uterus is smaller than anticipated. Diagnosis is confirmed through ultrasound scanning.
In certain instances, addressing the underlying condition might be feasible, although it might not always be achievable, especially if the fetus isn’t progressing as expected. If oligohydramnios emerges early in pregnancy, it often leads to a miscarriage. During later stages of pregnancy, the pressure exerted by the uterus on the fetus could result in deformities like talipes (club-foot).
