Contemporary society is an advanced society, a rapidly developing society, advanced science and technology and perfect equipment bring a lot of convenience and welfare to people’s lives. At the same time, it also protects people’s health. How to protect the health of the baby? Perhaps some pregnant women understand that a good prenatal checkup is necessary for a healthy baby to be born, but there are still pregnant women who wonder, what are the benefits of prenatal checkups? Do you have to do it? In response to these doubts of pregnant mothers, I would like to share my opinion here. 1, you can predict the degree of difficulty of childbirth: prenatal examination of the role of childbirth is also very large, through a comprehensive systematic examination, you can learn how the fetus in the mother’s posture and development, and then make predictions, to understand the degree of difficulty of childbirth, to be able to take appropriate measures to make up for it. 2, you can learn about the development of the fetus: the mother-to-be regularly go to the hospital for prenatal checkups, through the hysteroscopy, you can learn about the development of the fetus, whether there are any abnormalities, such as stunted, deformed, etc., if there are abnormalities can take timely remedial measures to protect the mother-to-be and the health of the fetus. If it is impossible to continue to have children, it is necessary to terminate the pregnancy. 3, early detection of pregnancy complications: the health of the mother-to-be during pregnancy is very important, not only in relation to their own health, but also in relation to the healthy growth and development of the fetus. Through prenatal examination, we can find out whether the mother-to-be has pregnancy complications, such as gestational toxicity, placenta praevia, early placental abruption, etc. These complications can seriously affect the health of the mother-to-be and the fetus, and if they are detected, they can be treated in time. 4, can be timely detection of disease: the mother-to-be to do prenatal examination, need to conduct a comprehensive examination to understand the mother-to-be’s developmental health status, but also to correct some physical defects, etc.. If some diseases that are not suitable for childbirth are found, such as heart disease, hypertension, diabetes and other systemic diseases, these diseases can not bear the burden caused by childbirth may make the corresponding organ dysfunction, affecting the normal physiology of the whole body, then the birth can be terminated.
