The sudden disappearance and reduction of the pregnancy reaction may be a sign of fetal arrest, which also needs to be judged in conjunction with ultrasound and laboratory tests.
Pregnancy reaction refers to the early pregnancy reaction, which is caused by the increase of hormone levels in the pregnant woman’s body after pregnancy, and most of them will appear at about 6 weeks after menopause, and disappear naturally at about 12 weeks of pregnancy. So the disappearance of early pregnancy reaction may be a physiological phenomenon. However, if there is an abnormal situation such as fetal termination, the hormone level in the body drops, which will also lead to the sudden disappearance of the early pregnancy reaction, and you need to go to the hospital for medical treatment.
Early pregnancy should also pay attention to appropriate rest, can not be tired and strenuous exercise, can not be coitus, need to follow the doctor’s advice to take folic acid on time. However, when the early pregnancy reaction suddenly disappeared to reduce the need to go to the hospital, ultrasound and blood HCG (human chorionic gonadotropin) test, to clarify the cause, if it is a fetal ejection, the need for timely removal.
In clinical practice, when the pregnancy reaction suddenly disappears and decreases, it is necessary to go to the hospital and find out the cause under the guidance of the doctor.
