There is no special pre-pregnancy check-ups. Routine check-ups are sufficient, and there are no special check-ups for mothers-to-be before pregnancy, mainly to find out if there are any underlying diseases, such as hypertension, diabetes, kidney disease, uterine fibroids, cervical lesions and so on. Routine check-ups will provide a preliminary screening for these diseases. If there are abnormalities or a history of disease, it is always necessary to see a doctor for consultation. If you have a history of abnormalities or illnesses, you should consult a doctor at a hospital. If you have no previous history of rubella virus immunization or potential infection (which can be detected by blood tests), you can receive rubella virus vaccination before pregnancy to reduce the risk of infection to your child during pregnancy. Cell phones and computers do not need to be protected, with the protection you may not know This point seems to be more difficult for urban women, in the whole country is full of toxic air, toxic food, harmful ionizing radiation environment, you do not know whether the space you work and live in is safe. But for some environments that are clearly harmful or should be removed, such as men in a long-term high temperature environment is not conducive to sperm development, women should avoid taking potentially teratogenic drugs (in fact, most drugs are still relatively safe, if there are some underlying diseases, such as hyperthyroidism, the benefits of medication is better than the risks associated with uncontrolled hyperthyroidism, whether the specific need to stop medication before pregnancy, please follow medical advice ), avoid noisy environment. Cell phones and computers have been proven to be free of potential risks to the fetus and can be used. Things like radiation-protective clothing are again a bit too much, and there is no evidence to prove what role they can play. Folic acid has benefits, but not every woman is deficient Folic acid is proven to reduce the incidence of anencephaly and neural tube abnormalities, deficiency of folic acid mainly occurs in certain areas where there is a lack of vegetables, if the diet is normal, no supplementation of folic acid is also possible. In addition, if you are taking a multivitamin such as Maternal, Elavil, SunCure, etc., which already contains 0.4mg of folic acid, then there is no need to take additional separate folic acid supplements. Cats and dogs do not need to be sent away It is a big misconception that you cannot have cats and dogs if you are pregnant. In the past, it was thought that cats and dogs had diseases such as toxoplasmosis, which would lead to deformities in the child, but in fact, dogs do not have much chance of transmitting diseases, and cats are not all hosts of toxoplasmosis, and people will only get toxoplasmosis if they eat the stool of a cat infected with toxoplasmosis. So not being exposed to dogs and cats during pregnancy was a misconception of many doctors in the past. If you are really worried, check the TORCH program to see if you have Toxoplasma, rubella, herpes simplex, CMV and other viral infections, and only recent infections (IgM positive) will be meaningful. In the past, our hospital also used TORCH as a screening indicator for every pregnant woman, but later on, because of its high false-positive rate and screening results suggesting little significance, screening for this indicator has also been eliminated.
