Fetal immobility refers to a decrease in the frequency of fetal movement, which may be due to physiological reasons such as an increase in the number of months of pregnancy, or pathological reasons such as intrauterine hypoxia and embryonic arrest.
1. Increase in the month of pregnancy: when the pregnant woman enters the late stage of pregnancy, the volume of the fetus increases, the space for the fetus to move in the uterus decreases, and the amniotic fluid gradually decreases, so the fetus does not like to move, but it can be up to 3-4 times per hour, which is normal at this time.
2. Intrauterine hypoxia: If the amniotic fluid of the pregnant woman is too small, the umbilical cord of the fetus is wrapped around the neck, or the pregnant woman has high blood pressure and other diseases, it may lead to intrauterine hypoxia of the fetus, and the mobility decreases, thus the number of fetal movements decreases significantly.
3. Embryonic arrest: If a pregnant woman is infected by microorganisms such as Listeria monocytogenes, it may affect the development of the fetus and cause it to suffer from embryonic arrest. When the fetus dies in the uterus, there is a possibility of a significant decrease in fetal movement.
When there is a significant decrease in fetal movement, pregnant women are advised to seek medical attention for fetal heart monitoring. If the fetal heartbeat monitoring is normal, there is no need to worry excessively. If the fetal heartbeat monitoring is abnormal, appropriate methods of intervention are required under the guidance of the doctor.
