Q: Do I need to wear radiation protection clothing after pregnancy? A: No. In early pregnancy, the cumulative radiation dose to the fetus has to reach 5-10 Rad before it is likely to cause a significant increase in the incidence of fetal birth defects. Take the radiation of the most common radiology examination as an example, the radiation dose to the fetus from a single abdominal X-ray is 100mRad, which means it takes 50 consecutive abdominal X-rays to reach the radiation dose that may harm the fetus. In daily life, it is impossible for a pregnant woman to reach this radiation dose. In general, if it is necessary to be exposed to radiation professionally, only then consider wearing radiation protection clothing, and only if it is a professional level of radiation protection clothing that really works. For professional women very worried about the computer radiation, is also a rumor. The radiation is likely to be from the large TV sets and computer monitors that used cathode ray tubes in the 70’s and 80’s. Even then, the amount of radiation from TV sets and computer monitors was relatively small, so there is no need to worry too much. Nowadays, computers and televisions are flat panels with LCD screens, which theoretically do not produce radiation with obvious adverse effects on the fetus. Some people argue that everything has radiation! Well, if you believe these “bricks and mortar” words, if you have more money at home and no place to spend it, then you buy it, you wear it! Q: Will the calcium supplement make the baby’s head too hard to be born? A: I’ve often been asked this question by mothers-to-be, saying that on various mother-baby forums people say that they shouldn’t take calcium supplements in late pregnancy, otherwise the fetal head will be too hard or the biparietal diameter will be too large to be born, and it will also lead to placental aging. Why is it that no one believes what doctors say that is based on science, but they believe these odd claims on the internet? I would like to ask you all, where are the sources of these strange claims? What is the basis for them? And it’s not just the mothers-to-be who believe in it, some doctors believe in this nonsense too! One of my patients told me during an office visit that her community doctor was very responsible and called her specifically to tell her not to take calcium supplements during late pregnancy because it would make the baby’s head too hard to be born! Well, I’ll say it three times: Calcium supplementation will not cause a hard head and placental calcification, no, no! Q: Do I need to take DHA supplements during pregnancy? A: This is a controversial issue and there is not yet a complete consensus, so I won’t simply say NO. The reason for suggesting DHA supplementation during pregnancy is that someone observed a phenomenon that the children of fishermen from coastal areas are smarter than the children of farmers from inland areas. It was thought that it might have something to do with the fact that pregnant women in coastal areas often eat fish, but later it was discovered that it might be the DHA from deep-sea fish that did the trick, so research on DHA supplementation during pregnancy began and found that the IQ of children born with DHA increased compared to those born without DHA supplementation. Of course, not every study comes to the same conclusion, and in general, there are more studies that suggest that DHA supplementation is effective. Nowadays, there are DHA products from deep-sea fish oil and also from seaweed. There is no harm in eating DHA, there may be benefits, so my personal opinion is: not against, but also will not be as a regular recommendation. PS: IQ determines entry, EQ determines success! Is it so important to have a few points difference in IQ? Some people care a lot, some people don’t care, well, I’m not involved, to supplement or not to supplement, you decide for yourselves! Q: Do I need to take bird’s nest when I’m pregnant? A: Actually, bird’s nest is not as nutritious as you think, its price is seriously deviated from the nutritional value. But if your family is too rich and wants to be capricious, then you buy it and you make up for it! PS: The autumn breeze is up and crab feet are itchy, it’s hairy crab season again, and a lot of moms-to-be are stupid enough to ask me if they can eat hairy crabs. In fact, I wrote the article, you have not seriously look, know you lazy, I will say it three times, I hope you can remember this time: can, can, can! Not only can you eat hairy crabs, but you can also eat chili, hot pot, and ice cream! It’s great! But don’t go too far, just satisfy your craving, don’t eat it as a meal! Otherwise, even if your husband has no opinion, your mother will have an opinion, and even if your mother also has no opinion, your mother-in-law will have an opinion! Q: Can climbing the stairs make me give birth faster? A: More activity will make your birth smoother, but not necessarily make you start contractions sooner, so far the motive of human birth is still unclear, this is definitely a Nobel Prize research project, interested people come to study ah! Sorry for going off topic, hurry back to “climbing stairs”. It is recommended that pregnant women who are about to give birth walk more, but do not advocate more “stair climbing”. One is afraid to grasp the bad, fainting and falling, the second is with the “illegal construction” out of the belly more climbing stairs is not good for the knees.
