The reason for frequent fetal movement at 37 weeks is more, it may be due to physiological reasons such as maternal or external environment leading to frequent fetal movement, or it may be due to pathological reasons such as intrauterine hypoxia of the fetus, which need to be combined with specific performance to determine. 1, physiological reasons: the pregnant woman’s posture change, mood swings, and strong sound, strong light stimulation, etc., can cause changes in fetal movement. If the pregnant woman is more relaxed after eating or bathing, it can affect the fetus and cause an increase in fetal movement. In addition, the fetal movement is more active in the early morning, generally the value of fetal movement in 3-5 times per hour is normal, as long as pay attention to the regular maternity checkup, strengthen fetal heart monitoring can be; 2, pathological reasons: if the fetus usually fetal movement is not frequent, in 37 weeks suddenly increased, more than 1 times than the usual frequency, or appear intermittent agitation, need to consider whether the fetus exists intrauterine hypoxia. In case of intrauterine hypoxia, the fetus can be regulated by oxygen intake and left side lying. If the abnormal fetal movement can be relieved, you can continue to wait for delivery for observation. If the frequent fetal movement does not disappear after symptomatic treatment, you should go to the hospital in time to improve the ultrasound examination to check the situation of the fetus in the uterine cavity, and you can consider terminating the pregnancy at the right time if the fetus shows signs of hypoxia.
