However, it is one of the less common amniotic fluid causes. This condition can happen at any point in your pregnancy. It is common to experience leaking of fluid due to ruptured membranes. Several problems with the placenta including a partial abruption (peeling away of placenta from the inner wall of the uterus) can cause low amniotic fluid. Common conditions contributing to this illness are diabetes, hypertension, preeclampsia and lupus. Underlying health concerns in the mother before or during pregnancy can also lead to low amniotic fluid. Several factors contribute to low amniotic fluid causes:Ī baby who is considerably smaller in size will produce less amount of amniotic fluid leading to oligohydramnios. There are no exact and identifiable low amniotic causes that we know of. Low amniotic fluid can also be an indicator of an underlying condition. This condition can also increase your chances of pregnancy and birthing complications. Low amniotic fluid can cause various health problems in your fetus affecting your baby’s development. This condition is medically known as oligohydramnios. Low amniotic fluid is a condition in which the amniotic fluid is at lower levels than expected as per your baby’s gestational age. By full-term pregnancy, that is, by 40 weeks of gestation, the amniotic fluid is about 600 mL. Additionally, amniotic fluid supports the development of your baby’s digestive and respiratory systems.Īccording to the Amniotic Fluid Index measurement, the amount of amniotic fluid is 800 mL (greatest at 34 weeks of gestation). It also allows the safe movement of the fetus in the womb. The function of amniotic fluid is to protect the unborn baby from infections, umbilical cord compressions, injury and temperature changes in the body. It is a protective liquid that forms inside the amniotic sac nearly after 12 days of conception. Each of these tests has a relatively high false-positive rate (i.e., 50 percent) in the low-risk patient.Amniotic fluid is a clear, slightly yellow-coloured liquid that develops around the fetus during pregnancy. In controlled trials, Doppler analysis has been associated with improved outcome, 1 although it is considered experimental by the American College of Obstetricians and Gynecologists. The use of Doppler flow velocimetry, usually of the umbilical artery, identifies the growth-restricted fetus at greatest risk for neonatal morbidity and mortality. The biophysical profile involves assessment of fetal well-being with a combination of the nonstress test and four ultrasonographic parameters (amniotic fluid volume, respiratory movements, body movements and muscle tone). Options include the nonstress test, the biophysical profile and an oxytocin (Pitocin) challenge test. In any case, antenatal testing should be instituted. Although not of proven benefit, bed rest may maximize uterine blood flow. General management measures include treatment of maternal disease, cessation of substance abuse, good nutrition and institution of bed rest. The fetus should be monitored continuously during labor to minimize fetal hypoxia. Preterm delivery is indicated if the fetus shows evidence of abnormal function on biophysical profile testing. General management measures include treatment of maternal disease, good nutrition and institution of bed rest. Serial ultrasonograms are important for monitoring growth restriction, and management must be individualized. A lag in fundal height of 4 cm or more suggests IUGR. Growth restriction is classified as symmetric and asymmetric. Ultrasound biometry is the gold standard for assessment of fetal size and the amount of amniotic fluid. Accurate dating early in pregnancy is essential for a diagnosis of IUGR. Certain pregnancies are at high risk for growth restriction, although a substantial percentage of cases occur in the general obstetric population. Identification of IUGR is crucial because proper evaluation and management can result in a favorable outcome. Intrauterine growth restriction (IUGR) is a common diagnosis in obstetrics and carries an increased risk of perinatal mortality and morbidity.
