Hypertension during pregnancy can affect the fetus, including fetal growth restriction, intrauterine distress, fetal death, etc. It needs to be analyzed specifically. 1. Fetal growth restriction: Hypertension during pregnancy can lead to reduction of amniotic fluid volume in pregnant women, insufficient oxygen supply to the fetus, developmental malformations, poor development of the fetal lungs, and damage to the fetal nervous system. 2. Fetal intrauterine distress: it is a comprehensive symptom that the fetus’s health and life are jeopardized by lack of oxygen in the uterus. Hypertension in pregnancy will reduce the placental perfusion, and the fetus will not be supplied with enough oxygen, forming acute and chronic intrauterine distress of the fetus. 3. Fetal death: Severe gestational hypertension is prone to placental abruption, as well as severe inadequate oxygen supply to the fetus may lead to fetal death. Hypertension during pregnancy should be treated in a timely manner in the hospital, complete the relevant examinations, under the guidance of the doctor symptomatic treatment.
