Nowadays, there are many only children, for the matter of pregnancy is a little too much attention. 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, 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, uterine fibroids, cervical lesions and so on. Routine check-ups will provide a preliminary screening for these diseases. If there is an abnormality or a history of disease, it is definitely necessary to go to the hospital to see a doctor for consultation. 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 don’t know if 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. Radiation-protective clothing is again a bit too much, there is no evidence to prove what role they can play. 4, supplemental multivitamins and folic acid: folic acid is proven to reduce the occurrence of anencephaly and neural tube abnormalities, 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: pregnant can not keep dogs and cats is a big misconception, in the past, dogs and cats have toxoplasmosis and other diseases, will lead to child deformities, but in fact, dogs do not have much chance of transmitting diseases, cats are not all hosts of toxoplasmosis, people will only be infected with toxoplasmosis if they eat the stool of cats infected with toxoplasmosis, so do not contact dogs and cats during pregnancy is a misconception of many doctors in the past, if it is really 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 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.
