The fetus absorbs nutrition from the mother through the placenta and umbilical cord. If the pregnant woman is hungry and does not consume enough energy, the fetus will also feel it and will remind the pregnant woman that it is time to eat through fetal movement, which is manifested as frequent fetal movement, and if the hunger is further aggravated, fetal movement may be weakened. If the fetal movement is increased due to hunger itself, it will gradually improve after eating. If the fetal movement is still abnormally active after eating, you should be alert to the possibility of intrauterine hypoxia of the fetus, and it is recommended to go to the local hospital to improve the ultrasound, electronic fetal heart monitoring and other tests. The fetus grows faster in the middle and late stages of pregnancy, and the pregnant woman’s metabolism is also faster, so she needs more nutrition. If you diet to control your weight, you may cause intrauterine growth retardation.
