After a woman is pregnant, due to the growth and development of the fetus and the needs of the pregnant woman, sufficient nutrients must be obtained from the diet. The quality of pregnant women’s nutrition not only directly affects the growth and development of the fetus, but is also vital to the development of the infant’s brain cells and future intellectual development. Therefore, effective measures must be taken before the child is born, that is, during the fetal period, to ensure that every child can grow up healthily.

During pregnancy, there are many changes in the metabolism of substances in the body and the functions of various organ systems. During pregnancy, the fetus and its appendages, placenta, and amniotic fluid gradually grow. The mother's own uterus and breasts grow due to endocrine changes, and the interstitial fluid increases. The whole body stores 2-4 kilograms of fat. In the early stages of pregnancy, there is little or no weight gain due to pregnancy reactions. Since morning sickness, the weekly weight has increased by about 50 grams. Starting from the 28th week of pregnancy, an increase of about 300 grams per week. The fetus has to absorb a large amount of nutrients from the mother for its own growth and development. If you do not pay attention to the nutrition during pregnancy, it is easy to cause the pregnant women to be undernourished or even to suffer from nutritional deficiencies.

Use the doppler fetal monitor to view the heartbeat of the fetus in the abdomen, observe the fetus at all times, and pay attention to his growth.
