Polyhydramnios in late pregnancy refers to the situation where the amount of amniotic fluid in pregnant women significantly exceeds the normal range in late pregnancy. Under normal circumstances, the change in amniotic fluid volume in pregnant women is a dynamic process that changes with the development of the fetus and different stages of pregnancy. However, when the amount of amniotic fluid exceeds the normal range, it may have certain effects on maternal and fetal health.

The following are some common reasons: Abnormal placental function: The placenta provides nutrition and oxygen to the fetus. If the placenta functions abnormally, it may cause difficulty in excretion of fetal urine, resulting in polyhydramnios. Fetal congenital anomalies: Certain fetal congenital anomalies, such as fetal urinary system malformations, fetal digestive system malformations, etc., may cause fetal urine excretion not to be smooth, resulting in polyhydramnios. Diabetes in pregnant women: Diabetes is a common metabolic disease. When pregnant women suffer from diabetes, the fetus does not produce enough insulin, leading to increased urinary excretion in the fetus, resulting in polyhydramnios. Multiple pregnancy: Multiple pregnancy is when a pregnant woman is pregnant with two or more fetuses at the same time. Because multiple fetuses produce urine at the same time, the amniotic fluid is too high. Infections in pregnant women: If pregnant women are infected with certain viruses or bacteria during pregnancy, it may cause increased fetal urine excretion, resulting in polyhydramnios. When a pregnant woman has too much amniotic fluid, it may have a certain impact on the health of the mother and fetus. For pregnant women, having too much amniotic fluid may increase the risk of premature rupture of membranes and placental abruption, leading to premature birth. For the fetus, excess amniotic fluid may increase the risk of complications such as fetal distress, fetal malposition, and umbilical cord prolapse. Treatment for polyhydramnios in late pregnancy generally needs to be based on specific circumstances. Doctors may recommend that pregnant women undergo routine prenatal examinations, including fetal heart rate monitoring, ultrasound examinations, etc., to understand the health of the fetus. If the cause of polyhydramnios in pregnant women is a congenital abnormality of the fetus or abnormal placental function, further examination and treatment may be required. If a pregnant woman has diabetes, blood sugar levels need to be controlled to reduce the risk of increased urinary excretion by the fetus. In short, excessive amniotic fluid in late pregnancy may be caused by a variety of reasons, which may have a certain impact on the health of the mother and fetus. Expectant mothers should maintain good living habits, conduct regular prenatal check-ups, and promptly detect and deal with excessive amniotic fluid to ensure the health of mother and baby. At the same time, for pregnant women with polyhydramnios, reasonable treatment and management are also crucial.
