After pregnancy, women's bodies will definitely undergo some changes, such as weight gain and emotional instability, which are all normal. After the months gradually increase, the fetus will also experience fetal heart rate. If the fetal heart rate is abnormal, pregnant women's emotions will inevitably fluctuate greatly, fearing that the child will have some problems, especially when the child is about to be born, they will be even more nervous. So why is the fetal heart rate unstable in children who are about to be born?

If a fetus about to be born experiences fetal heart instability, it may first be caused by hypoxia in the uterus; Secondly, if the pregnant woman has physical problems, it can also lead to unstable fetal heart rate. For example, if the pregnant woman suffers from hyperthyroidism or has adverse symptoms such as fever, it can cause the fetal heart rate to be too fast; Furthermore, if pregnant women take some medication during pregnancy, it may also cause both the pregnant woman and the fetus to experience rapid fetal heart rate. It is recommended to undergo a check-up as soon as possible.
Pregnant women can go to the hospital for fetal heart monitoring to observe whether the fetus has the possibility of congenital heart disease. If this physiological disease is excluded, it may be caused by external factors. During pregnancy, mothers should listen more to the fetal movements to prevent hypoxia in the fetus in a timely manner. It is necessary to go to the hospital for prenatal check ups more often to ensure the physical health of the fetus.
Pregnant women must pay attention to keeping their mood happy during pregnancy, which is also very important. If they are in a state of anxiety and unease for a long time, it will definitely have a certain impact on the health of the fetus.
