Nowadays, there are many only children, and there is some over-emphasis on the matter of pregnancy. From the medical point of view, the preparation work needed before pregnancy is not as much as imagined, listed below: 1, physical examination Routine check-ups can be done, and there is no special check-up for the mother-to-be before pregnancy, mainly to understand whether the body has basic diseases, such as hypertension, diabetes, kidney disease, 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 definitely necessary to see a doctor for consultation at the hospital. 2. Vaccine If there is no previous history of rubella virus immunization and no potential infection (which can be detected by blood tests), you can get a rubella virus vaccination in advance of pregnancy to reduce the risk of infection to your child during pregnancy. 3, avoid contact with toxic environment This point seems to be difficult for urban women, when 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 there are clearly harmful environment or should be detached, such as men in the long-term high temperature environment is not conducive to the development of sperm, women should avoid taking potentially teratogenic drugs (in fact, most of the drugs are still relatively safe, if some basic diseases, such as hyperthyroidism, the benefits of medication is better than the risks associated with uncontrolled hyperthyroidism, the specific need to stop medication before pregnancy, please follow medical advice ), avoid noisy environments. Cell phones and computers have now been proven to have no potential risk to the fetus and are available. Something like radiation-protective clothing is again a bit too much, there is no evidence to prove what kind of role they can play. 4, supplemental multivitamins and folic acid Folic acid is proven to reduce the occurrence of anencephaly and neural tube abnormalities, the lack of folic acid mainly occurs in certain areas where there is a lack of vegetables, if the diet is normal, no supplemental folic acid is also possible. In addition, if you are taking multivitamins such as Maternal, Elavil, and Sun Cun, which already contain 0.4mg of folic acid, then you do not need to supplement folic acid separately. 5, about pets It is a big misconception that you cannot keep dogs and cats when you are pregnant. In the past, it was thought that dogs and cats had diseases such as toxoplasmosis, which would lead to deformities in children, 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 cats infected with toxoplasmosis, so it is a misconception of many doctors not to contact dogs and cats during pregnancy. worried, check the TORCH program to see if you have Toxoplasma gondii, 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 pregnancy and delivery, but later, because of its high false-positive rate and screening results suggesting little significance, screening for this indicator has also been eliminated.
