A hypothyroidism is also the abbreviation of "thyroid dysfunction". It is a clinical syndrome caused by the lack of or lacking or lack of effects of thyroid hormones, or insufficient effects, or inadequate thyroid hormone physiological effects and insufficient biological effects.For some pregnant women, the question they is very worried is whether the hypertrophic pregnancy has an impact on the fetus.
So, how does pregnant women’s hypothyroidism affect the fetus?How to spend pregnancy safely?
Poor pregnancy and fetal risk of hypothyroidism during pregnancy
How does hypothyroidism affect the fetus during pregnancy?For pregnant women, clinical hypothyroidism during pregnancy can increase the risk of adverse pregnancy ending, such as premature birth, abortion, premature placenta peeling, low weight, etc. At the same time, it can also affect the baby’s intellectual development, neurotrophic ability and exercise ability, etc.Essence
This is because the thyroid gland is an important endocrine organs in the human body. The secretion of thyroxine involves the growth and development of the body and the metabolic regulation of each organ system. Among them, it is also a hormone necessary for the fetal brain neuroscope.
Before 20 weeks of pregnancy, the fetus was the first stage of rapid development of the fetus, and because the fetal poineroxine of the fetus started to secrete thyroid hormone until 12 weeks of pregnancy, the thyroid function began to be completely established after 20 weeks.
Therefore, before 20 weeks of pregnancy, the thyroid hormone required for the growth and development of the fetus is almost completely transported by the mother. During this time, if the thyroid function in the pregnant mother’s own body is normal, it can ensure that there is a sufficient amount of sufficient amountThe thyroid hormone is transported to the fetus through the placenta to meet the needs of the fetal’s first brain rapid development period for thyroid hormones.
However, due to the increased physiological demand for thyroid hormones during pregnancy, the thyroid gland is in this "stress" state. If it cannot adapt to the corresponding pregnancy changes, the pregnancy period of pregnancy may occur.
Once the thyroxine of the mother’s body is reduced in various periods of pregnancy, even if it is minor or short -term reduction, it can affect the fetal brain development to varying degrees. This damage is mostly irreversible.Children are short and intelligent, commonly known as "dysfunction".
How can pregnant women safe during pregnancy?
A hypothyroidism during pregnancy can increase the risk of adverse pregnancy endings. In order to reduce the occurrence of these adverse pregnancy endings, we should do a good job of pre -pregnancy and pregnancy health care:
1. It is recommended that women should adjust their body to the best state before pregnancy before pregnancy, and early health care to pre -pregnancy.
For hypothyroidism women who are preparing to be pregnant, do not interrupt the treatment of thyroid hormones without authorization before or during pregnancy, so as not to stop the symptoms of disappearing after the drug discontinue drugs, causing irreversible damage to the organs.Under the guidance of a doctor, adjust the drug according to need, so that the thyroid function before pregnancy can reach or approach the normal level, adjust the body to a suitable state before preparing for pregnancy, and do follow -up and monitor during pregnancy.
2. During pregnancy, a good checkup should be performed to advocate the screening of thyroid hormones and antibodies on all early pregnancy, not just a thyroid gland with a history of thyroid disease or related family history or corresponding symptoms.Inspection of function, monitor the levels of TSH, FT3, FT4, and TPOA in their bodies, and evaluate whether the reserve and compensation function of the A gland are evaluated according to whether the TSH is in a particular reference range.
Once abnormalities occur, actively cooperate with the doctor’s treatment to achieve early, early diagnosis, and early treatment, and reduce the occurrence of bad pregnancy ending.
3. Regarding the previous history of hypothyroidism, but in the newly diagnosed clinical hypothyroidism during pregnancy, some pregnant women are worried that drug treatment will have an impact on the fetus and refuse to be treated.Immediately under the guidance of a professional doctor, the body can be adjusted as soon as possible to a state where the body is adjusted as soon as possible.
For pregnant women with positive antibodies and normal thyroid function, they can be treated or not treated.However, the thyroid function is required regularly, because during pregnancy, the thyroid function is still the possibility of deterioration. Once the serum TSH exceeds the normal range during the monitoring process, it should be given immediately.
The guards have always advocated the alternative of levial thyroxine for pure thyroid antibody positive pregnant women and simple hypotonal aininemia pregnant women.Because if these pregnant women should be treated a few years later, what should I do if pregnant women who have not received treatment now?Moreover, this treatment is good or not?Absolutely harmless.
Recently, there are many mothers who consult on Weibo and WeChat, and many of them are about whether they should supplement iodine.Should expectant mothers supplement iodine?What method does iodine supplement iodine?How much iodine should I make up every day?When will the iodine supplement last?There should be a credible answer to this series of questions.So if the merchants have promoted the N kinds of iodine supplementation through the media or the Internet, should pregnant women believe it?
Studies have found that female iodine supplementation and pregnancy during pregnancy can help improve their baby IQ and health.A number of research reports determined that the lack of iodine during pregnancy, and the IQ of newborns can be reduced by 10–20 points.In addition, severe iodine deficiency during pregnancy can lead to children’s mental disorders and slow development, and low IQ.International organizations such as the World Health Organization and the European Food Safety Administration suggested that in addition to consumption of iodized salt during pregnant women and lactating women, more iodine should be supplemented by 150-200 micrograms per day.So, do pregnant women eat iodized salt?Do I have to replenish iodine after eating iodized salt?Why didn’t the doctor call a pregnant woman supplement iodine?
The effect of iodine deficiency on women, fetuses and babies
Severe iodine deficiency in pregnancy can affect the synthesis of pregnancy women and fetal thyroid hormone synthesis.The reduction of serum thyroxine levels can stimulate pituitary gland to secrete thyroid hormone (TSH), causing pregnancy women and fetal goiter.Severe iodine deficiency can lead to the increase in women’s abortion rate, death rate and perinatal infant mortality rate.Because the level of thyroid hormone is normal is the basis for ensuring the migration of the fetal brain neuron and the formation of myelin sheath. Although the fetus needs to obtain sufficient thyroid hormone during the entire pregnancy, it is particularly important in the first to 5 months of pregnancy.Severe iodine deficiency in pregnancy can lead to a decline in cognitive function of their offspring and Katin disease.
When the median urinary iodine of the female group of pregnancy in a region is 50 ~ 150 μg/L, it can be considered that there is a mild to moderate iodine deficiency. The crowd may occur in thyroid.There is no concentration, polymorphism, etc.
1. iodine is the trace element of the human body and the raw material for manufacturing thyroid hormones. The thyroid hormone is very important for the body and intellectual development of the fetus and infants.If the level of thyroid hormones in the fetus or infants is low, it will inevitably reduce the IQ of the baby, and it may also cause "small symptoms", that is, the children will have symptoms such as poor milk, drowsiness, dull expression, and do not like laughter.
2. In areas of iodine deficiency, clinically, it is often found that pregnant women’s nailing glands and fetal placenta are competing for iodine, and the disadvantage of the placenta is obvious.Therefore, when iodine deficiency areas, women supplement iodine during pregnancy can effectively prevent iodine deficiency in infants and young children.
3. Of course, if the mother has enough iodine supply, the fetal hormone levels will not be lowered.Unless the fetus has congenital thyroid defects or dysplasia, this is generally rare.
Do you know the background of the "Salt Salt and Iodine Policy"?
More than ten years ago, in order to solve the problem of iodine deficiency in more than 700 million in China, the state announced the "Regulations on the Management of Salt and iodine to eliminate iodine deficiency", requiring that in addition to eight high iodine areas, consumption of salt in other areas must be mandatory iodine.
Iodine deficiency will not only cause thyroid enlargement, but also affect the development of the body (including weight, height) and intelligence.It is under this premise that my country has implemented the method of adding iodine in edible salt, which is a measure of benefit the country and the people.
Do pregnant women do not need to supplement iodine after eating iodized salt?
In view of the different sources of food from all over the world, corresponding strategies should be formulated according to the diet models of various places and the consumption of iodized salt to ensure that women have appropriate iodine intake before pregnancy, pregnancy, and lactation.
Because it is difficult to determine how much iodine the United States Society (ATA) pushes or lactating women per day of daily iodine per day of pregnancy or lactating women.In order to ensure that those women are planning to be pregnancy, pregnancy, or lactating women, they can reach the total amount of 250 ° g daily intake. ATA also recommends that daily nutritional supplements that should be orally should be orally.Because iodized salt and daily foods can provide 100 micrograms per day.This nutritional supplement should contain potassium iodide, not products made of seaweed, kelp, etc., and the iodine content in the latter is unstable.This is why we are referred to as "food supplementation is not reliable".
Can I eat more kelp supplementation?
Do you understand now?Normally, iodized salt can only provide the most basic iodine intake (100 micrograms) every day.This amount can only meet the mother’s own demand for iodine, and it cannot meet the baby’s demand for iodine!For pregnant women and breastfeeding women, the iodine that should be consumed every day should be 250-300 micrograms.
Some people say that I can eat more kelp, can I supplement iodine?As mentioned earlier, the iodine content in these foods is unstable.Moreover, who can eat hundreds of grams of kelp a day?Can you eat it every day?
The iodine supplement must be supplemented by the drug.Food supplementation is not reliable, and iodine supplementation can only be used as auxiliary means.
There was a mother who said that her mother bought her a carton kelp when she was pregnant.However, now I want to vomit when I see maritime affairs.I asked her, do you want to vomit the words "kelp"?
