After pregnancy, women often need to go to the hospital for corresponding examinations in order to detect the growth and development status of the fetus in a timely manner, the most common of which is ultrasound examination. However, some people believe that doing too many ultrasound examinations may damage the growth and development of the fetus. So, shouldn't prenatal ultrasound be done frequently?
Yes, in most organs of the human body, damaging a few cells is not important, but if it damages reproductive cells or embryos in a sensitive developmental stage, the consequences are serious. So, try not to have more than 3 ultrasound scans during pregnancy. Performing gynecological ultrasound during early pregnancy has a certain impact on newborns, while newborns who have undergone gynecological ultrasound in the middle and late stages of pregnancy have not shown any adverse effects. Therefore, gynecological ultrasound examinations during early pregnancy should be used with caution.
It is generally believed that ultrasound is a non-invasive and non-destructive examination for the subject, especially compared to X-ray, MRI and other examination instruments, ultrasound is relatively safe for the human body. But ultrasound is still a form of energy, and when it reaches a certain dose, it will produce biological effects in the subject's body, causing damage to the local cells where the biological effects occur.
During pregnancy, it is generally necessary to undergo three B-ultrasound examinations, namely at 18-30 weeks of pregnancy, 28-30 weeks of pregnancy, and 37-40 weeks of pregnancy. The first B-ultrasound is used to examine and understand the condition of singleton or multiple pregnancies, the second B-ultrasound is used for prenatal screening, and the third B-ultrasound is used for pre delivery evaluation. If the ultrasound examination is performed too early or the examination is maintained for too long, it may cause certain harm to the fetus.
