Can I still prepare for pregnancy after going through security check? If I am pregnant, will my child be deformed if I pass the security check? These two questions are one of the most frequently asked questions. The first question is about pregnancy preparation. Traditionally, people are taught that pregnancy preparation requires a number of months of preparation, such as 3 months of abstinence from smoking and alcohol, avoiding exposure to toxic and harmful environments, and of course, avoiding X-rays with radiation as much as possible. According to the requirements of security screening equipment, the dose of radiation is usually very low, usually less than 0.25 microsieverts per exposure to the equipment just to understand the shape of the object, and these X-rays often do not penetrate the skin and cannot have an effect on ovarian function. In fact, worry about the impact of security screening equipment, it is better to worry about the amount of exposure to radiation during the plane’s travel at high altitude, according to statistics, 1 hour of flight, the exposure to radiation dose at about 10 microsieverts, while in the natural environment, the background radiation for 1 hour is also at about 0.35 microsieverts. In other words, even if you are exposed to hospital X-rays (roughly 1000 times the dose of a security check), for example, if you have a hysterosalpingogram that month, it is not generally recommended to use contraception for 3 months, you can get pregnant that month. If the eggs are damaged by the radiation, the serious ones cannot become a child and are miscarried in the middle of the process, and the ones with mild problems may not be detected. So, don’t worry, just let nature take its course. Coming back to the 2nd question, is it still possible to continue to carry a pregnancy if you are pregnant and undergo an amputation? In other words, if the child is affected, it will either miscarry or survive without being affected. 2 weeks later, then it is not particularly good to say that in the first 3 months, it is a critical time for teratogenicity, which of course is also related to the dose of X-ray exposure. The higher the dose, the greater the chance of occurrence. As mentioned earlier, the dose from the screening equipment is theoretically much lower than the radiation dose from X-rays in the hospital and should not be a big concern. The issue of malformations is of concern to all of us. Currently, medical screening for chromosomal abnormalities and structural malformations of the fetal body that occur during pregnancy can be done through blood draws or ultrasound malformations during pregnancy, and ultrasound screening between 20 and 24 weeks is especially important, as some large structural malformations can be detected during that ultrasound, and if they are detected, you can choose to induce labor at that time. Of course, current medical tools are not infallible, and despite the various measures currently in place to screen for birth abnormalities, the incidence of birth abnormalities is still at 1 to 2%.
