Women with preeclampsia who become pregnant again are much more likely to develop preeclampsia, as well as a variety of serious complications such as placental abruption, preterm labor, and fetal growth restriction. Pre-eclampsia is high blood pressure and proteinuria that occurs after 20 weeks of pregnancy and can manifest as headaches, edema of the hands and feet, blurred vision and even convulsions. Serious complications such as placental abruption, preterm labor, fetal growth restriction, maternal death or fetal death may also occur. Therefore, preeclampsia requires active treatment to control the progress of the disease and to ensure the safety of the mother and child. If a woman with pre-eclampsia becomes pregnant again, the probability of developing pre-eclampsia or even eclampsia will increase significantly, and the probability of the above clinical manifestations and complications will also increase greatly. It is recommended to control the blood pressure under the guidance of a doctor and monitor the condition of the mother and child closely.
