For women who have experienced five miscarriages, there may indeed be persistent effects on subsequent pregnancies. Recurrent miscarriages often indicate underlying maternal pathological factors, and without systematic diagnosis and treatment, they may lead to risks such as abnormal embryonic development and fetal distress. Therefore, it is crucial to take this seriously and implement scientific interventions.

Recurrent miscarriages may affect the normal development process of the embryo. Due to ineffective improvement of maternal conditions or intrinsic embryonic factors, structural abnormalities such as neural tube defects or congenital heart defects are more likely to occur in the early stages of fetal development. This is closely related to decreased stability of the intrauterine environment and abnormal placental function.

Fetal nervous system development may also be affected. If the mother has immune dysregulation or metabolic abnormalities, repeated miscarriages suggest impaired pregnancy maintenance mechanisms, which may indirectly affect fetal cerebral blood supply and nutrient delivery, potentially leading to neurodevelopmental delays. This requires dynamic monitoring through specialized early pregnancy screenings.

Placental dysfunction is a common secondary issue following recurrent miscarriages. A history of miscarriages may reduce endometrial receptivity, subsequently affecting placental implantation depth and blood supply establishment, increasing the risk of fetal hypoxia. This condition can be assessed through ultrasound blood flow monitoring of the umbilical artery resistance index.

Additionally, recurrent pregnancy loss may increase the risk of complications such as preterm birth and low birth weight. Women with such history are advised to complete comprehensive etiological screening before pregnancy, including karyotype analysis, immune antibody testing, and uterine cavity evaluation. During pregnancy, intensified fetal growth monitoring is required, with standardized prenatal care to promptly identify any issues.
