Generally speaking, fetal movement may be caused by acute intrauterine distress, mood swings, or lack of amniotic fluid, etc. The details are as follows: 1. Acute intrauterine distress: it may be due to abnormalities of the umbilical cord or excessive uterine contractions. Acute intrauterine oxygen deprivation of the fetus caused by obstruction of blood and oxygen supply between mother and fetus and blood circulation in the umbilical cord causes the fetus to move all the time, which can be relieved by timely oxygen intake or lying on the left side of the body. It is recommended to go to the hospital to do fetal heart monitoring and follow the doctor’s instructions. 2. Mood swings: Mood swings occur when the mother is frightened or over-excited. When there are mood swings, breathing will be accelerated and the body will consume oxygen, affecting the blood and oxygen supply of the fetus, which will result in the phenomenon that the fetus keeps moving. You can avoid this phenomenon by calming your mind, paying attention to rest, and relieving emotional fluctuations. 3. Lack of amniotic fluid: Lack of amniotic fluid will change the environment in the uterine cavity, causing hypoxia, which will be manifested in the phenomenon of non-stop fetal movement, and you can go to the hospital for intravenous rehydration. In normal times, we should pay attention to rest, avoid overwork. Reasonable diet, don’t have pressure, and regular maternity checkups. If the situation is serious, you should seek medical treatment immediately to avoid adverse consequences.
