After 34 weeks of oxygen intake, the fetus still moves less, considering that it is a normal phenomenon, may also be caused by the umbilical cord around the neck, placental dysfunction and other reasons. 1. Normal phenomenon: some fetus itself is not particularly love to move, even after inhaling oxygen fetal movement will be less than normal, general 12 hours fetal movement more than 20 times, considered normal. 2. Umbilical cord around the neck: if fetal hypoxia is caused by umbilical cord around the neck, even after oxygen intake, fetal movement may not increase, this is mainly because the umbilical cord around the neck is more serious, affecting the blood circulation of the fetus, resulting in fetal distress such as hypoxia and other fetal distress, and at the same time, also limit the activity of the fetus. 3. Placental malfunction: If the placenta has problems, it can’t provide sufficient oxygen and nutrition for the fetus, and fetal distress will also occur, leading to fetal hypoxia, so the fetal movement is less. If the fetus still moves less after 34 weeks of oxygen, there may be other reasons, so we suggest that you go to the hospital in time to improve the examination and clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
