Why does the early pregnancy reaction suddenly disappear?

Early pregnancy reactions are caused by sudden changes in the body's hormone levels during pregnancy. Sometimes the early pregnancy reactions disappear suddenly. This is due to changes in hormone levels in the body, and sometimes it can even have adverse effects on the health of the embryo. Therefore, when the early pregnancy reactions suddenly disappear, you must go to the hospital for a regular check-up as soon as possible to avoid affecting the fetus.

The disappearance of early pregnancy reactions is likely a sign of fetal arrest, because during the early development of the embryo, three important hormone levels are required, one is estrogen, one is progesterone, and one is chorionic gonadotropin. If the mother's own endogenous hormones are insufficient, it will cause the embryo to arrest, thus causing the sudden disappearance of early pregnancy reactions. The consequences of fetal development arrest are very serious. Most mothers will have a miscarriage after fetal development arrest. There are also cases where fetal arrest has no symptoms or is not diagnosed. If the dead fetus remains in the mother's body for a long time, it may cause maternal hemolytic disorder, which may cause heavy bleeding during delivery and may even be life-threatening.

Female friends whose early pregnancy reactions disappear can also go to the hospital for an ultrasound. The doctor will tell you the specific answer based on the examination results. During the examination, the doctor will check whether the size of the uterus is inconsistent with the gestational age. If the uterus is smaller than the gestational age, it proves that the fetus has stopped developing. Generally, the early pregnancy reaction disappears three months before the birth, and it is considered that the fetus has stopped developing, so it is best to be mentally prepared.

Early pregnancy reactions during pregnancy vary from person to person, and according to the different physical conditions of pregnant women, the physical fitness varies. Generally, early pregnancy reactions will gradually decrease after 3 months of pregnancy. As long as pregnant women relax, try to maintain a good attitude, do some aerobic exercise in moderation, supplement balanced nutrition, and don't overwork, it will generally not cause any effects on the fetus. If abdominal pain and bleeding in the lower body occur during pregnancy, you should go to the hospital in time for examination and don't blindly take supplements.
