Several factors can lead to oligohydramnios, including:
Rupture of membranes: Premature rupture of the amniotic sac can cause fluid leakage. Placental insufficiency: Poor placental function leads to reduced blood flow and nutrient delivery to the fetus. Maternal conditions: Chronic hypertension, diabetes, and preeclampsia can contribute to low amniotic fluid levels. Fetal conditions: Congenital anomalies, especially those affecting the urinary system, can result in oligohydramnios. Post-term pregnancy: Amniotic fluid levels naturally decrease after 42 weeks of gestation.
