Oligohydramnios (Low Amniotic Fluid)

When your doctor told you your amniotic fluid was low, you likely trusted they’d monitor it closely. But if that monitoring never happened or happened too late, your baby may have suffered preventable harm.

Oligohydramnios requires vigilant medical attention, and when your healthcare providers miss the signs, it can put both the mother and baby at risk. Below, you’ll learn how low amniotic fluid can lead to serious harm and what families can do when medical negligence is to blame.

What Is Oligohydramnios?

Oligohydramnios is a medical condition that occurs when there is too little amniotic fluid surrounding a baby in the uterus during pregnancy. In early pregnancy, this fluid is mostly water; by around 20 weeks, it’s primarily made up of the baby’s urine. The baby breathes and swallows this fluid, which is essential for lung development, movement, and overall growth.

Amniotic fluid increases steadily around 34 weeks, but when levels drop too low, the risks become dangerously high. Oligohydramnios can lead to fetal distress, restricted growth, and even stillbirth.

Regardless of where you gave birth or received prenatal care, every patient deserves the same standard of medical monitoring. When that standard is ignored, Beam Legal Team holds negligent providers accountable.

We’ve seen firsthand how a single missed diagnosis can alter the course of a child’s life. If your child was harmed by medical negligence, we’re here to help you.

Causes of Oligohydramnios

Here are several causes of low amniotic fluid in babies:

1. Placental Insufficiency: When the placenta is not providing enough oxygen and nutrients to the fetus, the baby may respond by reducing urine production, one of the main sources of amniotic fluid. This condition is often associated with:

• • Intrauterine growth restriction (IUGR)
  • Placental aging or dysfunction

2. Fetal Anomalies: This includes problems with the development of the kidneys or the urinary tract that could cause less urine production, leading to lower levels of amniotic fluid.
3. Premature Rupture of Membrane (PROM): This occurs when the membranes rupture before the onset of labor, allowing amniotic fluid to leak out. Even small tears in the amniotic sac can lead to gradual fluid loss and decreased amniotic volume.
4. Postdate Pregnancy: A postdate pregnancy (one that goes over 42 weeks) can have low levels of amniotic fluid, which could be a result of declining placental function.
5. Maternal Complications: Conditions like dehydration, high blood pressure, preeclampsia, diabetes, or chronic hypoxia can all lower amniotic fluid levels. Many of these issues can be detected and managed early with proper prenatal testing. Failure to identify them in time may point to medical negligence

Diagnosis, Signs, and Symptoms of Oligohydramnios

The signs and symptoms can vary, but some of the most common include:

• Leaking of amniotic fluid
• A baby measuring smaller than expected for gestational age (a sign of intrauterine growth restriction, or IUGR)
• Low maternal weight gain
• Abdominal discomfort
• Preterm premature rupture of membranes (PPROM)
• Sudden drops in fetal heart rate
• Decreased or absent fetal movement

Diagnosis of oligohydramnios is made through ultrasound evaluation, particularly by measuring the amniotic fluid index (AFI). The AFI is calculated by dividing the uterus into four sections, measuring the depth of amniotic fluid in each, and adding these measurements together.

An AFI of less than 5 centimeters is diagnostic of oligohydramnios. When the AFI is between 5 and 10 centimeters, it’s considered borderline and can still lead to complications.

Another common measurement is the single deepest pocket (SDP) method: if the deepest pocket measures less than 2 centimeters, oligohydramnios is diagnosed. In rare cases, a dye-dilution method may be used to measure fluid volume, though ultrasound remains the standard diagnostic tool.

Proper diagnosis means checking your health regularly during pregnancy. If your doctor didn’t do the needed ultrasounds or read the results wrong, that could be considered medical negligence

Complications Associated With Oligohydramnios

Complications from oligohydramnios can occur before, during, and after delivery, including:

• Cerebral palsy
• Fetal heart rate
• Meconium aspiration
• Low APGAR scores at birth
• Low birth weight
• Admission to the neonatal intensive care unit
• Non-reactive non-stress test
• Cord prolapse

How Is Oligohydramnios Treated

Treating oligohydramnios focuses on prolonging pregnancy safely to allow the baby to grow while managing risks. Treatment depends on the severity, cause, symptoms, and timing during pregnancy. Common treatment approaches include:

• Increasing maternal hydration by drinking plenty of water can help raise amniotic fluid levels
• Rest and reduced physical activity to help maintain fluid levels.
• Frequent monitoring with ultrasounds to assess fluid volume and fetal well-being
• Amnioinfusion during labor, where a saline solution is added into the uterus to cushion the umbilical cord and reduce the risks of cord compression
• Managing underlying conditions such as diabetes or high blood pressure
• Antibiotics, if the amniotic sac has ruptured, to prevent infection
• Medications like corticosteroids are used to help mature the baby’s lungs if early delivery is anticipated
• Early delivery, which may be recommended if fluid levels become too low or if the baby shows signs of distress, balancing risks of prematurity and complications from low fluid

In cases of fetal urinary tract blockages causing oligohydramnios, surgical interventions like vesicoamniotic shunts may be considered. Families in Chicago can access specialized fetal treatment at several leading hospitals, including:

• Ann & Robert H. Lurie Children’s Hospital of Chicago: Renowned for pediatric and fetal surgery, it offers comprehensive care for fetal urinary tract interventions.
• The Chicago Institute for Fetal Health: Specialized in advanced fetal therapies, closely affiliated with Lurie Children’s Hospital.
• UChicago Medicine: It has a dedicated maternal-fetal medicine team experienced in prenatal interventions.
• Rush Fetal and Neonatal Medicine Center: They provide fetal medicine services with access to fetal surgical procedures.

Support Groups and Resources for Expectant Parents

Beyond medical care, emotional support can play a role for families struggling through pregnancy complications. Here are some local support options:

• Fetal and Infant Mortality Review: A peer-led support group for individuals who are pregnant or have recently had a baby, offering a space to share experiences and resources.
• Chicago Family Picnic: Provides classes and workshops on childbirth education, breastfeeding, and parenting, along with support groups for moms and dads.
• Wildflower Centre: They specialize in perinatal and family mental health therapy with support groups and workshops for individuals and families experiencing pregnancy challenges
