Taboo Questions and Answers for Pregnant Women-Behavior

Q 1。 Can I have sex when I am pregnant? Do I have to wear condoms?

There are three points to pay attention to about sexual life during pregnancy:

1. Basically, except for several high-risk pregnancies (such as placenta previa, prenatal bleeding, emergency abortion, cervical atresia), you can have sex throughout pregnancy.

2. During sexual intercourse, if pregnant women have strong uterine contraction, abnormal bleeding, severe lower abdominal pain, etc. They should stop sexual intercourse and seek medical treatment as soon as possible.

3. Condoms should be worn during sexual intercourse to reduce vaginal inflammation, cervical inflammation and early water breakthrough.

Q2。 Can I put a sore cream or a salon bath on my back pain?

During pregnancy, as the fetus grows up day by day, the weight of the entire lumbar spine, pelvis and muscle base of the expectant mother will gradually increase. Therefore, in the self-care and health care of lying-in women, the correct posture and the protection of lumbar vertebrae should be given priority. If you have symptoms of backache, you should first seek medical attention to find out whether it is ligament injury, nerve compression or premature delivery. As for whether you can wear ointment or Sharon Bass, it is only normal physical discomfort after seeing a doctor, so it is appropriate to use it under the guidance of a doctor.

Q3。 Must I sleep on the left?

It is recommended that pregnant women lie on their left side when sleeping, so as not to oppress the lower abdominal vein, resulting in poor blood return and edema. However, the relative position of the uterus and inferior vena cava of each pregnant woman is not the same. Therefore, if pregnant women feel uncomfortable lying on the left side, they can lie on the right side instead, or put a pillow between their legs and raise their legs slightly, which is ok.

Q4。 Can I swim or ride an exercise bike when I am pregnant?

Proper gymnastics during childbirth is not only helpful to the progress of labor, but also can effectively relieve the discomfort symptoms such as backache, headache and shoulder pain. However, exercise should be limited, not too tired or have bad breath. Among them, swimming is a good and safe exercise, because water can reduce gravity and support the body of pregnant women. Riding an exercise bike is also a good choice, but pay attention to protect the lumbar spine and knees for no more than 30 minutes, and take a proper rest and replenish water in the middle.

Q5。 Does the use of microwave ovens, mobile phones and computers affect the fetus?

Use microwave oven, mobile phone, computer, etc. There is not enough data to prove the influence of electromagnetic wave on fetus, which will affect the health of embryo and fetus; However, if pregnant women have to be exposed to the threat of electromagnetic waves for a long time, appropriate protective measures are still necessary, such as using protective clothing against electromagnetic waves to reduce exposure time and opportunities.

Doctor's words

Pregnancy is a lifelong event for women, especially the first pregnancy. Due to physical, psychological and physical changes, pregnant women are both expecting and afraid of being hurt. Modern mothers should believe in professional knowledge and technology, fully understand the pregnancy process, and welcome the arrival of newborns with a healthy attitude.

Q6。 Can't pregnant women have their hair cut or permed?

Cutting pregnant women's hair will not affect their physiological state in theory, and there will be no fetal malformation. It is rumored that pregnant women will use scissors or hammer nails to hint that the fetus is defective, which makes pregnant women more worried. If this statement is true, pregnant hairdressers cut the hair of pregnant women, who should be deformed? As for perm, the key is whether the perm liquid will be absorbed by pregnant women through the skin and affect the health of the fetus. Because perm is not a necessity in life, pregnant women should try to avoid perm, especially in the first pregnancy (from the first 13 week of pregnancy).

Q7。 Can pregnant women stay up late?

The normal life and rest of pregnant women contribute to the balance of various organ systems in the whole body, and then provide for the fetus? Set the growth environment. Often staying up late will affect the physical and mental health of pregnant women, which is not conducive to the growth of the fetus. In addition, the uterus is getting bigger and bigger during pregnancy, which will gradually oppress the inferior vena cava, making the venous return of the lower body poor, which is easy to cause varicose veins of the lower limbs and perineum and hemorrhoids. Often staying up late and reducing the sleep time of lying flat (preferably lying on the left side) will make the above symptoms more serious.

Q8。 Do pregnant women have to go to obstetrics and gynecology when they are sick?

Experts also have the responsibility to be fully familiar with the drugs that individuals often use and whether these drugs can be prescribed by pregnant women. When a pregnant woman is sick, besides the diseases that are known or being treated, she can first see the obstetrics and gynecology department for preliminary examination, and then refer to various specialties for follow-up diagnosis and treatment if necessary. Generally speaking, if a pregnant woman has a cold, urethritis, cystitis or unexplained lower abdominal pain, she can consult an obstetrician first. If you have asthma and chest tightness, you should see a chest doctor; Gastric acid reflux, stomach pain or epigastric pain should be diagnosed and treated by gastroenterologists; Trauma should be seen by a surgeon; If the skin has a severe rash or itching, please see a dermatologist; Please call a dentist when you have a toothache; If joint dislocation and fracture are suspected, please call an orthopedic surgeon.

Q9。 Can pregnant women have a spa or massage?

Spa and massage are not absolute taboos for pregnant women. Pay attention to water when doing SPA? And the pressure of the water column, avoid soaking in hot water that exceeds body temperature for a long time for the first pregnancy, and avoid high-pressure water column hitting the abdomen for the third pregnancy. Pregnant women can do local massage on their limbs. As for the substantial stretching massage of trunk muscles, it is better to avoid it as much as possible! What if? Are you very concerned about whether you "moved the tire"? Perhaps it is best not to do SPA and massage, so as not to cause psychological burden.

Q 10。 Can pregnant women go abroad by plane?

The restrictions or regulations of airlines on pregnant women's flight are not worried that the change of high-altitude air pressure will threaten the health of pregnant women and fetuses. In the third trimester, especially for pregnant women who are getting closer to the expected date of delivery, if there are signs of pain, water breakthrough or bleeding during the long-distance flight, based on humanitarian standpoint, the plane must be forced to land at the nearest airport for medical treatment, which will lead to flight delay and fuel loss (high cost), which may also lead to the trouble of "plane jump incident". Don't worry too much when the pregnant women who are pregnant for the first time and the second time fly abroad! Please forgive me for the third pregnancy, and then go abroad to play after giving birth!

Doctor's words

Being pregnant is a happy thing. Don't believe groundless rumors or reports casually, which will cause psychological pressure. For example, the recent report about "umbilical cord around neck" has aroused the concern and nervousness of many pregnant women. In fact, some long umbilical cords are easy to knot if they wander freely in the amniotic cavity with limited space; Putting the umbilical cord on your head and reducing the length of the floating umbilical cord is the most reliable "self-help" method. According to the statistics of Njuming Hospital 1993, the incidence of umbilical cord around the neck is about 22%, the fetal mortality rate is 4.4‰, and the mortality rate of umbilical cord around the neck is 3.3‰, even lower. The statistical results are completely opposite. So just relax, find a reliable obstetrician and do a good job of prenatal examination.

Q 1 1。 Can I apply acne cream?

There are four common ingredients in acne ointment on the market: azalea acid, antibiotics, benzene peroxide and vitamin A acid. Rhododendron and antibiotics are classified as Class B in the pregnancy classification of Food and Drug Administration (FDA), which means that animal tests can't show danger, but there are not enough reports on human trials, so doctors should evaluate the efficacy and risks before using them cautiously. Benzene peroxide and vitamin A acid belong to Grade C, indicating that animal experiments have teratogenic effects, but they have not been fully studied in human experiments, so they should be avoided as much as possible during pregnancy.

Q 12。 Can I ride a motorcycle or drive a car?

Elders always warn pregnant women to go out less, so as not to get fetal gas; In fact, this does not mean that pregnant mothers have to stay at home. After all, there are many pregnant mothers in the modern workplace. If you don't feel unwell, such as premature delivery such as bleeding or abdominal pain, you can still drive a car or ride a motorcycle cautiously. Be sure to wear a seat belt when driving, and avoid sitting sideways when riding a motorcycle. However, at the end of pregnancy, especially near the expected date of delivery, the stomach has obviously bulged. Driving or riding a motorcycle with a big stomach will naturally increase the risk rate, so you should avoid driving or riding a motorcycle alone.

Q 13。 Can I take a hot spring bath?

Soaking in hot springs or taking a bath can really relax tired and tense muscles, promote blood circulation of lower limbs, relieve edema and improve back pain. Pregnant mommy can also soak in hot springs or take a bath. However, try to avoid hot springs in the early pregnancy to avoid the discomfort of premature delivery. When soaking in hot springs, pay attention to whether the water quality is clean, the water temperature should not exceed 40 degrees Celsius, and the soaking time should not be too long. Replenish water in time to avoid dehydration due to excessive sweating. If you feel any discomfort during bathing, such as chest tightness, palpitation or shortness of breath, you must stop immediately to avoid the danger of affecting pregnancy.

Q 14。 Can I see a dentist if I am pregnant?

It is best for women to have their teeth examined before pregnancy. If they need dental treatment, it's best to do it before pregnancy. During pregnancy, if the teeth are uncomfortable, you can ask the dentist for temporary pain relief treatment, but if there is gum infection, you still need to ask the dentist for immediate treatment. The second stage of pregnancy is more suitable for dental treatment, but this period is based on the principle of emergency treatment, and it is best to postpone extensive and large-scale surgery until postpartum.

Q 15。 Can hanging clothes lead to miscarriage?

During pregnancy, due to the change of body shape and weight, it will be more difficult and uncomfortable for pregnant women to do some actions such as raising their arms and tiptoeing, and it is indeed easier to fall because of the unstable center of gravity. However, if you just dry clothes with careful actions in a safe environment, it will not affect pregnancy and lead to miscarriage.

Doctor's words

Timely examination and moderate rest are the correct concepts and attitudes that pregnant women should establish.

When the expectant mother has any problems, including physical and psychological, unknown and fearful, difficult to say, etc. Can she talk all the time? Some obstetricians will ask and consult, which can help pregnant mothers live a happy and healthy life during pregnancy.

Q 16。 Does climbing stairs help production?

It has been reported in China that the frequency of exercise during pregnancy is related to the progress of the second stage of labor (uterine dilatation to fetal birth), and pregnant women who exercise will shorten the waiting time and delivery time. Therefore, expectant mothers should have moderate and regular prenatal exercise on working days. Walking or climbing stairs is a good choice, which can not only strengthen cardiopulmonary function and physical strength, but also strengthen pelvic muscles, making the pelvis easier to open during production. Especially at the end of pregnancy, walking and climbing stairs can help the fetal head fall; However, when climbing stairs, you should pay attention to the center of gravity and try to avoid going down stairs, so as to avoid the burden and injury to the spine and knee joint caused by the increased weight.

Q 17。 Pregnant women listen to noisy music for a long time, will the baby cry badly in the future?

According to the current research report, pregnant women often listen to melodious and harmonious music, such as rivers and streams, insects and birds or classical music. The fetus can feel the rhythm and rhythm of music, which will also make pregnant women feel relaxed and blood vessels contract normally, which is of course beneficial to the growth of the fetus. In contrast, noisy high-frequency rhythm music, such as rock music and electronic music, is disliked by the fetus and is easy to show discomfort. Especially after seven months of pregnancy, it is the stage of fetal hearing development. Soft music can stimulate fetal hearing development and increase fetal comfort.

Q 18。 Is vaccination for pregnant women harmful to the fetus?

Try not to vaccinate during pregnancy, but during the epidemic of some diseases, some vaccines are harmless to the fetus, so you can consider injection. According to the source, vaccines are divided into three categories:

1. Live attenuated vaccine (German measles, chickenpox, measles, mumps, BCG, oral children? Arthritis vaccine, etc. ) is a live attenuated bacteria or virus, which will cause fetal infection and vaccination is not recommended.

2. Dead bacteria vaccine (influenza, Japanese encephalitis, rabies vaccine, etc. ) is made of dead bacteria, which is not contagious to the fetus and can be injected.

3. Toxoid vaccines (diphtheria and tetanus) made of toxoid secreted by bacteria will not infect the fetus and can be injected.

Q 19。 Can frequent ultrasound scanning deform the fetus?

Ultrasound is a kind of sound wave, there is no ion radiation crisis, and it will not cause trauma to pregnant women and fetuses. At present, prenatal ultrasound examination is quite safe and universal, and it is a necessary and routine tool for screening major congenital fetal malformations (intestinal obstruction, hydronephrosis, short limbs, rabbit lips, hydrocephalus, spina bifida and congenital heart disease, etc.). ). Sometimes ultrasound will be affected by different stages and postures of fetal development, and some limitations may require multiple ultrasound tracking. Expectant mothers can rest assured of their own safety.

Question 20. Can't lift heavy objects?

According to folklore, if pregnant women move, they have to move beds, wardrobes, etc. They will move to the "fetal spirit", which will make the fetus prone to miscarriage. From the point of view of modern medicine, it is meaningful. When pregnant women lift heavy objects, it may lead to lower abdomen exertion and uterine muscle contraction. If they accidentally hit the abdomen, it may also lead to bleeding or premature placental detachment. Therefore, if there is heavy work such as moving and lifting heavy objects during pregnancy, pregnant women should not do it by themselves, but they can find family or friends to do it for them to ensure the safety of the mother and fetus.

Doctor's words

In the era of underdeveloped medical care, the process of pregnancy and childbirth can only rely on the gods. For the safety of mothers and children, some taboos will be circulated among the people and recorded in the yellow calendar, which will be a reminder to the elders. From the perspective of modern science, in fact, some taboos are reasonable. It is absolutely right to be careful during pregnancy. As long as it is not too outrageous, it will affect the normal work and rest, and you can obey the opinions of the elderly a little. If the expectant mother is not sure, she can discuss with the obstetrician and gynecologist to solve her doubts, so as to avoid some suspicious problems and unnecessary psychological pressure.

Q 1。 Can drinking cold drinks or eating ice products cause contractions?

When you eat cold drinks, you will feel strange in your stomach. In fact, it is not cold drinks or ice products that cause contractions, but the low temperature of food, which causes gastrointestinal discomfort. Studies have shown that when pregnant women's hands come into contact with ice, the blood vessels in the uterus will contract, which will affect the blood circulation of the fetus and the growth of the fetus. Therefore, pregnant women should eat less food such as ice cream and popsicles. As for cold drinks, as long as they are stored at room temperature and the temperature exceeds 10℃.

Q2。 Can I eat spicy food?

A small amount of pepper has no effect on pregnant women and babies. Pepper contains substances that numb the nerves, which will affect the baby's nerves. Therefore, when pregnant mothers eat Chili, they must be careful not to eat Chili, so they can eat it in moderation. When eating Chili, if pregnant women master the principle of whether their mouths feel numb, they can feel at ease.

Q3。 Can I eat durian? Ginger, these hot and dry foods?

Liu? It will raise blood sugar in the body. Once the mother's blood sugar rises, the baby will be easily overweight, so what if the pregnant woman wants to eat durian? Each meal should not exceed the size of an orange, that is, about half a pomegranate? Yes, so as not to eat too much and cause the fetus to be too big. Although ginger is a hot and dry food, it is also a natural ingredient to improve the vomiting symptoms of pregnant women. Therefore, when cooking, put some ginger, about the size of thumb, which can slow down morning sickness, but don't eat too much!

Q4。 Is it easy to have an abortion when eating papaya and aloe?

Papaya contains female hormones, which can easily interfere with the hormonal changes in pregnant women, especially green papaya. Pregnant women should completely quit because it is not only harmful to the stability of the fetus, but also may lead to abortion. In Southeast Asian countries, local residents also eat papaya for contraception, which shows that papaya is not good for production. As for aloe vera, there have been animal experiments and it has been found that aloe vera can cause abortion in animals, so pregnant mothers should eat less.

Doctor's words

Expectant mothers must be careful when choosing food. If they eat inappropriate food, it is likely to affect their health and development. There are many taboos about pregnant women's diet. Expectant mothers are advised to consult doctors before listening to these taboos, so as to avoid unnecessary dangers caused by hearsay.

Q5。 Can't you drink or smoke?

If pregnant women smoke in the first three months after pregnancy, it may increase the chance of fetal cleft lip and palate. If you smoke or often inhale second-hand smoke during pregnancy, your baby is more likely to have learning disabilities or behavior problems in the future.

The third trimester is a stage in which a large number of fetal nerve cells communicate and connect with the brain. Alcohol can affect many neurotransmitters and cause serious damage to the development of fetal brain. Alcoholic women should give up drinking before pregnancy.

Q6。 Can I drink lieutenant general soup when I am pregnant?

Lieutenant general decoction is mainly used to warm up women's menstruation and relieve discomfort. According to Chinese medicine, there will be great anger during pregnancy. Drinking Zhongjiang decoction at this time may cause anxiety of getting angry. Some women have the habit of taking traditional Chinese medicine soup to regulate menstruation before pregnancy, and sometimes they still take it at the beginning of pregnancy because they don't know they are pregnant. According to Taiwan Province Tsumura Shuntiantang Company, taking Zhongzhong Decoction during pregnancy has no adverse effects on the fetus, but there will be physical changes after pregnancy. Therefore, it is suggested to stop drinking Chinese traditional medicine soup after confirming pregnancy.

Q7。 Cough can you eat Chuanbei loquat cream?

There are different formulas of Chuanbei loquat cream in the market, some of which contain "safflower", which is a contraceptive drug belonging to traditional Chinese medicine, so we must pay special attention when buying it. In fact, if you have any discomfort during pregnancy, you should discuss it with your doctor before dealing with it. Therefore, if you cough, you can take Chuanbei Loquat Cream. As long as the drug formula is determined, it can be taken with peace of mind after consultation with the doctor. In addition, the treatment of cough is not just eating Chuanbei Pipa cream, but there will naturally be a more suitable treatment method for pregnancy after seeing a doctor.

Q8。 Can pregnant women eat red ginseng or ginseng?

Clinically, Chinese medicine generally suggests that ginseng should be used only in the case of "qi deficiency", which can replenish qi and prevent miscarriage. For some pregnant women with febrile constitution, or pregnant women with febrile constitution in the third trimester of pregnancy, taking ginseng warming tonic may help fire the fetus and aggravate pregnancy discomfort. There are many kinds of ginseng, such as Korean ginseng, Jilin ginseng, Codonopsis pilosula and Pseudostellaria heterophylla. It is different from warm tonic, flat tonic or cold tonic, so it is best to take it after discussing with the doctor.

Q9。 Does the baby get jaundice when eating papaya?

The jaundice of the baby is mainly due to the increase of bilirubin in the blood, which leads to the yellowing of the sclera (the white part of the eye) and the skin. Excessive intake of red and yellow vegetables and fruits, such as carrots, pumpkins, papaya, oranges, Liu Ding, persimmons, mangoes, etc. , will make the blood carotene content is too high, and carotene will be deposited on the skin, thus making the skin yellow. However, there is no report of neonatal jaundice caused by eating papaya by pregnant women or lying-in women, and eating papaya has nothing to do with jaundice.

Doctor's words

You must avoid alcohol and tobacco when you are pregnant, because at different stages, it will have different effects. Especially for women who have smoking habits, their chances of getting pregnant will also be affected. Once pregnant, the probability of ectopic pregnancy will also increase. The possible effects of alcohol on the fetus include developmental retardation, too small head circumference, facial deformity, learning disabilities, memory disorders, hyperactivity and other symptoms. The last three months of pregnancy is the most serious period, so it is best not to drink alcohol during the whole pregnancy, so as not to affect the fetus. Remind pregnant mothers that staying away from alcohol and tobacco during pregnancy is the best way.

Q 10。 Eat bird's nest, can the baby avoid jaundice?

This statement has no basis in Chinese medicine. Bird's nest is sweet in taste, nourishing yin and moistening dryness, tonifying middle warmer and benefiting qi, and is generally used for post-illness conditioning in clinic. Bird's nest is regarded as a treasure, and I am afraid it has fallen into the trap of "rare things are precious". Because there are many differences in customs in different regions of the Chinese nation, pregnant women are encouraged to eat more bird's nest in some regions to enhance their physical fitness. However, it is still necessary to pay special attention to the fact that bird's nest contains animal protein, so pregnant women with special physique should be careful to eat bird's nest and cause allergic reactions.

Q 1 1。 Can you raise a fetus by eating more coptis, ginseng and medicinal liquor?

Coptis chinensis tastes bitter and cold. It has the functions of clearing away heat, promoting diuresis, purging fire and detoxifying, but if it is taken too much or for too long, it is easy to lose the stomach. However, Chinese medicine believes that there is evidence to use drugs. For example, some poor pregnancy (that is, vomiting during pregnancy) is caused by stomach heat, and it will also be treated with coptis in clinic.

If you blindly think that you are pregnant and weak, blindly taking warm and fiery supplements like ginseng is like adding fuel to the fire, which will inevitably lead to a sudden rise in internal heat and blood heat, which may lead to threatened abortion or prolonged labor and dystocia. Medicinal liquor contains alcohol, which has a great influence on the fetus, and expectant mothers must avoid it.

Q 12。 Can eating coix seed lead to miscarriage?

Coix seed is a kind of food and traditional Chinese medicine that people are familiar with and often eat. Its taste is sweet and light, and its nature is slightly cold. It has the functions of strengthening the spleen and stomach, promoting diuresis and eliminating dampness, clearing heat and expelling pus. However, the root of Coix lachryma-jobi was used for abortion in ancient books. In addition, the experimental study also found that coix seed oil can increase the excitability and contractility of rabbit and guinea pig uterus. In the book "Materia Medica Seeking Truth" in the Qing Dynasty, it was also mentioned: "Pregnant women should not be used indiscriminately. 」

Q 13。 Can pregnant women take Chinese medicine?

Many single Chinese herbal medicines with toxic and side effects often appear in Chinese patent medicines in the form of formulas, so it is especially necessary to be cautious when taking them. Chinese patent medicines that should be taboo mainly include Niuhuang Jiedu Pill, Niuhuang Qingxin Pill, rheumatism medicinal liquor and trauma medicine. Even the wound patch should be used with caution and should not be used for too long. Clinically, as long as the doctor is correct in syndrome differentiation and proper in medication, even if the drug is toxic and taboo, the disease can disappear. Therefore, once pregnant women get sick, they can still use more controversial drugs, but when their condition improves, they should consider stopping using these drugs.

Q 14。 Can't pregnant women drink coffee or tea?

Beverages such as coffee and tea contain caffeine, so expectant mothers should reduce the amount of coffee or tea in the first three months of pregnancy, and it is best not to drink either. Some related studies have pointed out that drinking too much coffee will increase the chances of fetal malformation, miscarriage and low birth weight. At the same time, the excitement of caffeine is likely to cause fetal arrhythmia, pregnant women's heartbeat is accelerated, and urination is increased, which invisibly increases the burden on the heart and kidneys, so pregnant women should think twice!

Doctor's words

Since ancient times, Chinese medicine has had so-called "contraindications to pregnancy". In terms of performance, the following drugs are mainly used.

1. products for promoting blood circulation and removing blood stasis-accelerate blood circulation, chase blood and overflow blood, and easily lead to abortion.

2.

3. the product of great cold and great heat-too cold means cold uterus, too hot means blood heat.

4. Descending products-This kind of descending traditional Chinese medicine often has diuretic or laxative effects. Excessive use will hurt yin and consume gas, leading to a decrease in fetal qi.

5. Toxic products-toxic fetal effects.

It is generally believed that Chinese medicine has no side effects. In fact, "it's a three-point poison", especially for expectant mothers in the first trimester, it's better to use it less.

13 contraindications during pregnancy

In order to ensure that pregnant women can successfully get through pregnancy and make the fetus in the abdomen develop healthily, pregnant women should pay attention to many problems in their daily life.

Green oil essence should not be used.

Green oil essence contains camphor, which can pass through the placenta and enter the amniotic cavity, causing nausea and vomiting in pregnant women.

Small note:

Pregnant women who are pregnant for 20-23 weeks should pay attention to the maintenance of weight and whether there is edema, and check it regularly every 4 weeks. In the meantime, production and baby products can be prepared.

Don't wear lipstick

The main components of lipstick are oil, wax, dyes and spices. Grease is usually lanolin, which can adsorb all kinds of heavy metals, trace elements and microorganisms such as Escherichia coli in the air, and has a certain infiltration effect. When talking, saliva may absorb harmful substances on the lips and make them invade the body.

Watching TV for a long time is not advisable.

Pregnant women who watch TV for a long time and are inactive will have edema of lower limbs.

Don't perm or dye your hair.

The cold perming agent used in perming contains basic thioglycolate and hydrogen oxide. Hair dyes are nitro and amino aromatic compounds. These substances are toxic and can cause rashes and respiratory diseases, which is not good for both mother and baby. In addition, perms and hair dryers can generate electromagnetic fields, which are harmful to fetal health. During pregnancy, the hair is fragile and the head is easy to fall off. If you perm your hair with chemicals, it will cause a lot of hair loss.

Don't touch the cat

Most cats are infected by arcuate parasites, and a large number of oocysts contained in their feces can survive to infect people. If pregnant women come into contact with cats or cat feces, it may cause fetal toxoplasmosis, leading to fetal abortion or malformation.

It is not advisable to use more detergents.

Some chemicals in detergent can denature or necrosis fertilized eggs. In the early stage of pregnancy, excessive use of washing powder, shampoo and detergent will be absorbed by the skin and stored in the body, which will denature the outer cell membrane of fertilized eggs and cause abortion. If women often use detergent, it will be absorbed to a certain concentration. After 48 hours of fertilization, it will denature the egg and lead to the death of the pregnant egg.

Not suitable for long-term contact with computers.

When using a computer, pregnant women's brains are highly concentrated and their nerves are excessively nervous. Low-frequency noise in the occupational environment will affect the fetal environment, and radiation, electromagnetic waves, electric waves and electrostatic appliances will be harmful to the health of mothers and babies. Long-term use of computers may lead to miscarriage, dystocia and premature delivery of pregnant women, and it is more likely to produce deformed fetuses.

It is not advisable to take a hot bath for too long.

Too long hot bath time for pregnant women may lead to fetal birth defects. A study examined the vaginal body temperature of 20% women of childbearing age, and found that the vaginal inner wall temperature reached 39℃ after 39℃ water bath 15 minutes or after 465438℃ water bath 1. 10 minutes, which would harm the central nervous system of the fetus. A study conducted by experts from Boston University Hospital in the United States found that babies born to pregnant women who took a hot bath or shower two months before pregnancy were three times more likely to suffer from neural connective tissue development defects than other pregnant women. If the body temperature often exceeds 38℃, it will have the same consequences. Because hyperthermia can inhibit it from exceeding 38℃, it will have the same consequences. Because high temperature can inhibit cell proliferation, damage capillaries and lead to abnormal development of nervous system.

Don't wear heavy makeup.

Many cosmetics have stimulating effects, such as alumina, zinc oxide and peroxide. Improper use can cause folliculitis, allergy and skin reaction to light. After pregnancy, women become rough and sensitive because of the imbalance of hormone secretion in the body. Excessive use of cosmetics is easy to cause rash. As long as the skin is clean, it will recover naturally after 5 months of pregnancy. Pregnant women can use ordinary cosmetics to make up, but avoid heavy makeup, so as not to cover up their illness but at the same time stimulate the skin. But hospitals should not wear makeup, otherwise it will affect doctors' examination and judgment.

It is not advisable to put flowers and plants in the room.

Flowers and plants should not be placed in the bedrooms of pregnant women and babies, because some flowers and plants will cause adverse reactions of pregnant women and babies. Some flowers and plants, such as evergreen, multicolored ball, hydrangea, cactus and primrose, are easy to cause contact allergy. If the skin of pregnant women and babies touches them, or their juice touches the skin, acute skin allergic reaction will occur, and symptoms such as painful tinea and skin mucosal edema will appear. There are also some fragrant flowers and plants, such as jasmine, daffodils, magnolia, cloves and so on. This can lead to pregnancy insensitivity, loss of appetite, and even symptoms such as headache, nausea and vomiting. Therefore, it is best not to put flowers and plants, especially fragrant potted flowers, in the bedrooms of pregnant women and babies.

Not suitable for prevention.

Vaccination reactions such as discomfort and fever caused by vaccination are not good for pregnant women and fetuses. Under normal circumstances, pregnant women should not be vaccinated. However, in case of accidents and emergencies, such as contact with diphtheria patients, trauma and being bitten by a mad dog, it is still necessary to vaccinate immediately.

It is not advisable to blow the electric fan for a long time.

The wind of electric fan blows on people's skin, which promotes the evaporation of sweat, makes the skin temperature drop suddenly, leads to the contraction of epidermal capillaries, the increase of peripheral resistance of blood vessels, the increase of blood pressure and the increase of heart burden. However, in the windy part, the skin temperature is still relatively high, the capillaries in the epidermis are in a relaxed state, and the blood flow increases. The head skin is rich in capillaries, obviously congested and sensitive to cold stimulation. Blowing an electric fan at the head can easily lead to dizziness and head pain. Because the electric fan only blows air to certain parts of the whole body, the body temperature is in a state of balance, so the nervous system and various organs and tissues must step up their work to regulate the body temperature. Therefore, using an electric fan for too long will make people dizzy, headache, fatigue and loss of appetite. Pregnant women must not spend too much time blowing electric fans, and it is best to blow them intermittently with a breeze.

Advice for pregnant women

Week 20-23

Fetal development status

(1) is about 30cm tall and weighs 600-700g.

(2) The fetal hair increases, and the hair and eyebrows grow out.

(3) During the development of toenails, the grasping reflex of hands is good.

(4) The skin is pink and wrinkled.

Electric blankets should not be used.

Due to high temperature or strenuous activity in the early pregnancy, the body temperature of pregnant women rises by 2℃, which is easy to cause the death of fetal brain cells, thus affecting the development of fetal brain. In addition, the electric blanket will produce electromagnetic field after being electrified, which will affect the development of fetal bones and lead to deformity.
