1, and the second child is an elderly pregnant woman.
Xinhua News Agency, Beijing (Reporter Fan) With the implementation of the comprehensive two-child policy, many elderly women choose to give birth again. However, medical experts say that old age will not only reduce fertility, but also significantly increase the probability of giving birth to deformed children. 35-year-old women, especially those over 40, must consult a doctor in advance to prevent complications and ensure the baby's health.
At the Ninth Healthy China Theme Forum held recently, Geng, deputy director of the Clinical Medicine Center of the Scientific Research Institute of the National Health and Family Planning Commission, said that after the launch of the comprehensive two-child policy, many post-70s and post-80s have joined the ranks of re-education, but older women, that is, women over 35, are facing higher reproductive risks, so it is suggested that women over 40 must consult a doctor first.
She said that some special groups, such as mothers who have had cesarean section, may have uterine rupture and even life-threatening with the gradual increase of the fetus when they give birth again. It is necessary to consult a doctor in advance to prevent risks.
Wang Lina, chief physician of Obstetrics and Gynecology Department of Peking University Third Hospital, said that women over the age of 35 are more likely to give birth to children with genetic defects, such as newborns who are prone to some congenital diseases, cardiovascular malformations, cleft lip and palate, so it is necessary to make good preparations before and during pregnancy.
In addition, infertility is also a common problem for older women. Professor Lu Qun, chief physician of Reproductive Center of Peking University People's Hospital, said that age plays a very important role in fertility, and age determines the quality and quantity of eggs. If you are over 35 years old and have not been pregnant for 6 months, you need to see a doctor for evaluation.
2. Precautions for pre-pregnancy preparation
1. Don't use cosmetics before pregnancy.
Many women have the habit of making up, especially using sunscreen or foundation every day, or using lead-containing cosmetics such as whitening cream. Adult skin care products, especially whitening products, will deposit in the body after use, and it usually takes three months to be completely discharged, so it is best to start using mild skin care products with little irritation to the skin within three months before pregnancy.
The better whitening effect, the higher the lead content of cosmetics. If there is too much lead in women's bodies, it will inevitably lead to various diseases after the baby is pregnant, such as hyperactivity, mental retardation and anemia. Therefore, from the beginning of pregnancy, it is best for women to use these lead-containing cosmetics less. Just keep your skin clean.
2, cooking should be iodized salt.
Iodine deficiency in women during pregnancy and early pregnancy will increase the risk of cretinism in newborns in the future. Iodine is one of the essential trace elements for human body. Iodine deficiency leads to decreased thyroxine synthesis and hypothyroidism, which further affects maternal and fetal metabolism, especially protein synthesis. Studies have shown that when the iodine intake in perinatal period and early pregnancy is less than 25 micrograms, newborns may suffer from cretinism, which is manifested as mental retardation, deafness, sexual retardation, motor skills disorder, language ability decline and other growth and development obstacles. Experts suggest that due to the relatively high demand for iodine before pregnancy and early pregnancy, in addition to iodized salt, it is also recommended to eat iodine-rich seafood at least once a week, such as kelp, seaweed, fish and shrimp.
Once a woman is pregnant, it is easy to lack iodine. Investigation shows that 30% pregnant women with mild iodine deficiency and 5% pregnant women with severe iodine deficiency will lead to abortion. Therefore, iodine supplementation should start before pregnancy. Although everyone uses iodized salt in cooking, thinking that iodine can be supplemented, many people are used to putting iodized salt in the cooking process. This practice easily leads to iodine volatilization, which seems to supplement iodine, but in fact it lacks iodine. The correct way is to add iodized salt after vegetables are cooked, so that iodine will not volatilize. You can also eat more seafood to supplement iodine at ordinary times.
3. You can use electrical appliances without restriction by wearing radiation protection clothes.
Women who are prepared usually wear radiation protection suits before pregnancy, thinking that this can completely block radiation and use computers, air conditioners or microwave ovens without restrictions, but it is not. Experts said that at present, the quality of radiation protection suits on the market is uneven, so it is difficult for ordinary consumers to judge, and whether radiation protection suits really protect against radiation remains to be verified.
4, diet should be taboo.
In the first six months of pregnancy, women should start to quit and not eat whatever they like. Give up eating raw aquatic products, such as sashimi and oysters. (shellfish) Bacteria and harmful microorganisms in these aquatic products can lead to miscarriage or stillbirth, and the survival time of microorganisms in human body is often beyond our imagination.
At the same time, give up women's favorite hot pot and barbecue. Because most cattle and sheep may be parasitic with Toxoplasma gondii, but human flesh is invisible. If you just put the fresh meat slices into the soup and eat them immediately, this short heating can't kill Toxoplasma gondii eggs parasitic in the cells of the meat slices, and the larvae can spread through the intestinal wall with the blood.
