Rachel Reed, a midwife mentions in this post that, “The amniotic fluid is constantly being produced and renewed : Baby swallows the fluid it is passed through the gut into the baby’s circulation then sent out through the placenta. Low amniotic fluid levels can sometimes be reversed with proper hydration.Īmniotic fluid can even be replaced after water has broken. This is one reason why so many people, from your OB to your mother-in-law, will encourage you to get adequate fluids during pregnancy. In fact, drinking water plentifully for a solid week has been shown to increase levels by a few points. Studies have found that drinking water has been shown to increase fluid levels.
In addition to these factors, some studies have found that amniotic fluid levels are not predictive of either good or bad fetal outcomes. In fact, many factors can influence findings, including: experience of your ultrasound tech, the position of your baby, and the amount of fluids consumed by the mother.
While the technology used to determine fluid levels is amazing, it may not be as foolproof as we like to think. Obstetrician Ernie Graham said, “Then we looked at the maternal demographics, we looked at the outcomes of the babies, and we found that the fluid measurements weren’t very predictive of babies that later had problems.”” Johns Hopkins investigators compared outcomes of 131 babies with low levels of fluid with an equal number of babies in the normal range. But is the technology used to determine amniotic fluid levels accurate? A Cochrane Review found that, “The accurate assessment of amniotic fluid volume by ultrasonography can be influenced by an inexperienced operator, fetal position, the probability of a transient change, and the different ultrasound diagnostic criteria of an abnormal volume.”ĭoctors often use the amount of amniotic fluid around a baby to measure health in the womb, believing that low fluid levels late in pregnancy indicate baby is endangered because it is not getting enough maternal blood. Technology used during pregnancy is an amazing tool that can help prevent and treat many problems overlooked in days past. Is Measurement of Amniotic Fluid Levels Accurate? It is helpful for women to know what levels are considered dangerous, what causes it, and if anything can be done to prevent low amniotic fluid levels. In childbirth and pregnancy, knowledge is power. In addition, while low levels are considered a problem, there is even disagreement on what is truly low and what is normal. This is partially due to the fact that measurements below a certain level are a cause for concern and indication of a real problem. Despite the normality of dropping levels, there can be worry surrounding this subject. It is normal to have some lowering of amniotic fluid levels towards the end of pregnancy, even for the healthiest of pregnancies. While both have some level of inaccuracy, studies currently support the use of the single deepest pocket method, finding that using AFI increases interventions such as induction and cesarean without improving maternal outcomes. The amniotic fluid index (AFI) or single deepest pocket (SDP) method. Low fluid levels, also known as oligohydramnios, is diagnosed in two different ways. Each couple deserves to better understand this important diagnosis and how it can impact their pregnancy and birth. The diagnosis of low fluid levels can bring feelings of worry and many questions about what this means for the mom and her baby.
