Fetal movement is not necessarily hypoxia, but when fetal movement is excessive followed by a decrease or disappearance of fetal movement may be fetal hypoxia. Fetal movement is usually recognized at about 20 weeks of gestation, and after 28 weeks of gestation, fetal movement should be counted in accordance with medical advice, and normal fetal movement is ≥10 times/2 hours. Fetal movement may occur after eating or appropriate activities, but will return to normal within a short period of time, which is a normal phenomenon. However, when frequent fetal movements are followed by a decrease or disappearance, it may indicate a risk of fetal hypoxia. Fetal movement counting in late pregnancy is an easy way to self-assess the condition of the fetus in the womb. When there is a decrease or disappearance of fetal movement, it is necessary to go to the hospital in time, and follow the doctor’s instructions to carry out ultrasonography, fetal umbilical cord blood flow monitoring, fetal biophysical scoring, fetal heart rate monitoring and other related examinations to fully evaluate the intrauterine condition of the fetus, and terminate the pregnancy at the appropriate time to protect the safety of mother and baby.
