Oligohydramnios is a condition during pregnancy characterized by a lower than normal amount of amniotic fluid surrounding the fetus. This can be detected via ultrasound when the amniotic fluid index (AFI) is less than 5 cm or the deepest pocket of fluid is less than 2 cm.
Causes of oligohydramnios can include:
Placental Issues: Insufficient blood flow to the placenta.
Fetal Conditions: Congenital anomalies affecting the kidneys or urinary tract.
Premature Rupture of Membranes: Leaking of amniotic fluid before labor.
Post-term Pregnancy: Being past the due date can lead to decreased amniotic fluid.
Maternal Factors: Conditions like dehydration, diabetes, or hypertension.
Potential Risks: Oligohydramnios can lead to complications such as fetal distress, preterm birth, and developmental issues. Regular monitoring and appropriate management are important.
