After pregnancy, women particularly hope that their fetus can grow up healthily. But there will always be some pregnant women who experience fetal cessation for some reason, most of which occur in the early stages of pregnancy. The occurrence of miscarriage during pregnancy is a significant blow to pregnant women. So, is there a lot of miscarriage at 21 weeks of pregnancy?
At 21 weeks of pregnancy, fetal arrest can also occur, but this situation is not common. Generally speaking, fetal arrest mostly occurs in the early stages of pregnancy, and by the 21st week of pregnancy, the occurrence of fetal arrest will decrease. At this time, fetal arrest is mostly caused by endocrine disorders, systemic diseases, and maternal fetal blood type incompatibility. Pregnant women should pay attention to the movement of the fetus when they can feel it, and seek medical attention promptly if any abnormalities are found.
At 21 weeks of pregnancy, fetal arrest may indicate developmental disorders in the fetus. For example, congenital defects, intrauterine growth retardation, and other conditions can all lead to fetal arrest. Some fetuses may experience asphyxia in utero, such as umbilical cord entanglement around the neck or insufficient amniotic fluid, which can lead to fetal hypoxia and acidosis, and in severe cases, fetal arrest. When the fetus experiences asphyxia, there will be a reaction in the fetal heart rate, so pregnant women should pay attention to the fetal heart rate and go to the hospital immediately if it continues to accelerate.
