1. Pregnant women taking certain medicines are indeed harmful to the fetus
1. The harm of pregnant women taking medicine to the fetus is related to the stage of pregnancy when taking medicine
Pregnancy from January to March is a critical period of embryogenesis, and the fetus is most sensitive to teratogenic factors. Generally speaking, all drugs are prohibited during pregnancy from January to March.
[Within 1 week after egg fertilization] At this stage, the fertilized egg has not been planted in the endometrium and is generally not affected by the drug;
[Within 1-2 weeks of fertilization] The fertilized egg has been planted in the endometrium, but the tissue has not yet differentiated. The effect of the drug may be abortion, but it does not cause deformities;
In the above two stages, if you accidentally take some medicines, it will not have too much impact on the fetus, so it is not necessary to cause abortion.
[3-8 weeks after fertilization (5-10 weeks after menopause)] belongs to the "highly teratogenic period", which is the period of differentiation and formation of various organs of the embryo, and is very susceptible to the influence of drugs and other external factors leading to fetal malformations.
At this stage, all drugs should be banned, including general health products and tonics. Among the medicines that have been in use, those that are available or that are temporarily discontinued should not be used. Do not assume that over-the-counter medicines are safe and easy to use. If you are sick, you should consult a doctor and make a careful choice after considering the needs of both the mother and the fetus. If you inadvertently take medication at this stage and choose to continue pregnancy, you can perform prenatal diagnosis (including ultrasound) at 16-20 weeks of pregnancy to further understand the growth and development of the fetus and rule out fetal malformations.
[After 12 weeks of pregnancy] The teratogenic effect of the drug on the fetus is significantly weakened, but the detoxification function of the fetal liver on the drug is not yet perfect, and the excretory function of the kidney is still far inferior to that of adults. The drug still has great side effects on the fetus, mainly related to Liver and urinary system. At this stage, once you become ill, your doctor may recommend taking some medicines marked with "pregnant women use with caution", and regularly monitor the pregnant women while taking the medicine. For drugs that are clearly marked with the words "prohibited by pregnant women," they should be avoided.
2. The harm of pregnant women taking medicine to the fetus is related to the type of medicine taken
After taking some medicines, expectant mothers will have a bad impact on fetal development. For example, tetracycline will affect the development of fetal teeth and bones; some antibacterial drugs such as sulfonamides have varying degrees of impact on all stages of pregnancy.
The US Food and Drug Administration (FDA) classifies medicines into 5 levels according to their harm to the fetus: A, B, C, D, and X. Grade A indicates that case-control studies have been conducted in humans to prove that there is no harm to the fetus; Grade B indicates that animal experiments are not dangerous to the fetus, but there are no human studies or animal experiments that have adverse effects, but there is still no good human Controlled study; class C indicates that there are no good animal experiments and human studies, or that it has been found to have adverse effects on animals, but there is no data to explain the problem in humans; class D is dangerous to the fetus, but its benefits outweigh the disadvantages during pregnancy , Sometimes still need to be used; level X indicates that the danger to the fetus has proved to be more harmful than beneficial, can be teratogenic or have serious adverse effects. Among them, except for A and B grade drugs that are safe for pregnant women and fetuses, others have side effects and hazards of varying degrees.
3. It is wrong to think that Chinese medicine has no toxic and side effects and can be taken during pregnancy!
Many people in life think that Chinese medicine has no toxic or side effects compared to Western medicine, and pregnant women can also use it with confidence. This is very wrong! Many traditional Chinese medicines contain alkaloids and chemical components that are very complex. Some traditional Chinese medicines are highly toxic and can directly or indirectly affect fetal development; some traditional Chinese medicines can stimulate the intestine and reflexively cause the uterus to contract strongly, leading to miscarriage and premature delivery; There are also some Chinese medicines that can stimulate the uterus, which can cause fetal ischemia and hypoxia in the fetus; moreover, the effects of the matching of various Chinese medicines are also very large, which may directly or indirectly affect the growth and development of the fetus. Therefore, in the first three months of pregnancy, in addition to Western medicines, pregnant women should also use the following 4 types of Chinese medicines: big poison and fever drugs, blood circulation and stasis drugs, slippery drugs, aromatic drugs, such as centipedes , Cinnabar, citrus aurantium, musk, pangolin, coix seed, clove, motherwort, angelica, etc. If you do n’t understand the properties of traditional Chinese medicine, if you want to use traditional Chinese medicine to cure a disease, you must consult Chinese medicine. You must not listen to remedies and advertisements and abuse Chinese medicine.
Second, but refused to take medicine to treat laissez-faire disease development is more harmful to the fetus and mother
After pregnancy, the enzymes in pregnant women have certain changes, which will have certain effects on the metabolism of certain drugs in the body. The drug is not easy to detoxify and excrete, which may cause some impact on the fetus. However, some diseases themselves are far more harmful to the fetus and the mother than the effects of drugs. Under the guidance of a doctor, the pros and cons should be weighed and the drugs should be used reasonably. Allowing the disease to develop without timely treatment will bring more health risks.
1. Chronic disease or pregnancy comorbidity Can not refuse treatment
For example, some pregnant women have chronic diseases such as hyperthyroidism, diabetes, high blood pressure, etc., or some complications of pregnancy, such as gestational diabetes, high blood pressure during pregnancy, etc. These diseases require medical treatment. If pregnant women and their families hold The stubborn point of view of "medication" refuses to accept medical treatment, so that some diseases that could be cured or controlled in time by medication will deteriorate and become serious and serious diseases. In fact, it will endanger the development of the fetus in the abdomen more seriously. In fact, many of the common drugs are relatively safe for the fetus and can be used under the guidance of a doctor.
2. Common diseases such as colds should be used according to the disease
For many common diseases, such as cold, fever, diarrhea, constipation, etc., if the symptoms are mild, dietary adjustments can be used for diet therapy. If the condition is serious, it cannot be delayed. For example, if the pregnant woman keeps high fever for a long time, it may cause the fetus to damage its brain cell development in an oxygen-deficient environment. Failure to control the condition in time may even cause miscarriage, premature delivery, and fetal congenital abnormalities. Even a stillbirth seriously threatens the health of mother and child. Therefore, expectant mothers during pregnancy should not take these "little diseases" lightly, and judge the degree of development of the disease under the guidance of a doctor, and treat and use drugs as appropriate. It is necessary to avoid the abuse of drugs and the aggravation of the disease.
