Low fetal movement at 22 weeks may be normal, such as the fetus is sleeping, or it may not be normal, such as intrauterine hypoxia.
Fetal movement at 22 weeks should be observed during the recent period of time, usually the number of fetal movements are normal, temporary low fetal movement may be the fetus is sleeping, and when the fetus is active the number of fetal movements will return to normal.
Fetal movements suddenly become more frequent for a period of time without rhythm, and then the number of fetal movements become less, this situation may be caused by intrauterine oxygen deficiency, such as fetal umbilical cord wrapped around the neck, umbilical cord kinks and other reasons.
The mere fact that there is little fetal movement at 22 weeks is not enough to determine whether the fetus is normal in the uterus, and it is recommended that you go to the hospital for an ultrasound examination to find out how the fetus is developing in the uterus.
The number of fetal movements at 22 weeks of pregnancy will generally increase gradually, but the development of each fetus is different, and the fetal movements shown will also be different.
