The causes of polyhydramnios can be multifactorial, including maternal, fetal, and placental factors. Some common causes include:
Maternal diabetes: Uncontrolled gestational diabetes can lead to increased amniotic fluid production. Fetal anomalies: Conditions such as gastrointestinal obstructions or neurological disorders can impair the fetus's ability to swallow amniotic fluid, leading to accumulation. Multiple pregnancies: Twin-to-twin transfusion syndrome can result in one twin having polyhydramnios. Infections: Certain infections, such as cytomegalovirus or syphilis, can contribute to the condition. Idiopathic: In some cases, the cause remains unknown.
