The fetus is moving all night. What's going on?

After a period of development in the pregnant woman's abdomen, the fetus will produce fetal movement, and the pregnant woman will have a clear feeling at this time. Fetal movement usually occurs in the second trimester of pregnancy. Fetal movement is a very happy thing for pregnant women, and it will make them feel excited. However, if the fetal movement is too frequent or the amplitude of the fetal movement is relatively large, it is also an abnormal phenomenon. So why does the fetus move all night?

First, why does the fetus move all night? There are physiological reasons. Frequent fetal movements in the late pregnancy are mostly caused by physiological reasons, including the following 5 situations: After a meal, the blood sugar level in the expectant mother's body increases, and the baby also has strength thanks to the mother, so the fetal movement will become more obvious than before a meal. When taking a bath in warm water, the expectant mother's blood circulation will be smoother, and her body and mind will be more relaxed. This pleasant mood will be conveyed to the baby, so the fetus's activities will become more frequent. In the late pregnancy, the fetus can already recognize the mother's voice. It likes to communicate with mom and dad through conversation. Therefore, when the expectant mother talks to the fetus, the baby will respond and express its feelings through frequent fetal movements. When the fetus is stimulated by music, it will become more fond of "movement", which is a way for the fetus to express joy. Usually the fetus is more active at night, on the one hand because it is more energetic at night, and on the other hand because the expectant mother can calm down and feel the baby's fetal movement at this time.

Second, pathological reasons. Expectant mothers need to be alert that not all frequent fetal movements in late pregnancy are normal. If the fetal movements have been sparse and suddenly become frequent, you should pay attention, because this may mean that the fetus is lacking oxygen or is being attacked by some disease.

Why does the fetus move all night? When the fetus suffers from hypoxia, it will become irritable and hyperactive. The number of fetal movements will increase in the early stages of hypoxia. When the intrauterine hypoxia continues to worsen, the fetal movements will gradually weaken and the number will decrease. This is a sign of danger to the fetus. If no emergency measures are taken at this time, the fetus will stop moving and even its heart rate will disappear, and the heart will stop beating, resulting in death. Common hypoxia can be seen in placental abruption, placenta previa, umbilical cord around the neck, etc. In addition, if the expectant mother suffers external impact during pregnancy, it may cause the fetal movement to suddenly accelerate and become violent, and may even cause miscarriage or premature birth.
