What it is
Oligohydramnios is a condition where the amount of amniotic fluid surrounding your baby is lower than expected, a measurement your care provider typically identifies during an ultrasound. This fluid is vital for your baby's development, providing cushioning, helping with lung and digestive system maturation, and allowing for movement. When diagnosed, it means the amniotic fluid index is less than 5cm or the maximum vertical pocket is less than 2cm.
This condition affects roughly 4% of pregnancies and can arise from various factors. Common causes include issues with the baby's urinary tract, which is often the case when diagnosed earlier in pregnancy. Other contributors can be problems with the placenta (uteroplacental insufficiency), premature rupture of membranes, also known as PPROM — Water Breaking Early, or if your pregnancy extends past your due date. When severe oligohydramnios occurs early in pregnancy, it can unfortunately impact the development of the baby's lungs, known as pulmonary hypoplasia.
What it tends to feel like
Receiving a diagnosis of oligohydramnios can bring a wave of concern and questions, even though you likely won't feel the 'low fluid' directly. This condition is usually discovered during routine ultrasounds or when your provider is investigating other concerns. The primary 'feeling' you might experience is the emotional weight of the diagnosis itself, coupled with the increased monitoring that often follows. Your care team may suggest more frequent non-stress tests (NSTs) and biophysical profiles to keep a close eye on your baby's well-being. This period of heightened observation can be a lot to navigate, and it's completely understandable to feel anxious as you await more information and clarity.
