Oligohydramnios can result from several factors, including:
Maternal health issues such as dehydration, hypertension, and diabetes. Placental problems such as placental insufficiency, which impairs the transfer of nutrients and oxygen. Fetal anomalies such as renal agenesis, where the fetus's kidneys do not develop, leading to reduced urine production. Rupture of membranes leading to leakage of amniotic fluid. Post-term pregnancy where the fluid naturally decreases after the due date.
