The most overlooked key nutrient during pregnancy-iodine

When you are pregnant, you may think of folic acid, calcium, DHA, iron, but there is another very important nutrient that many pregnant mothers ignore, that is iodine. Iodine is one of the essential trace elements for the human body, and it is essential for the synthesis of thyroid hormones and the development of the nervous system. Iodine deficiency is a worldwide health problem. About one-third of the world’s population suffers from insufficient iodine intake. What is the harm of iodine deficiency? Iodine deficiency in the fetal period and infants and young children will affect the development of the brain, severely causing idiotism, deafness, and mental retardation. Iodine deficiency during pregnancy can lead to miscarriage, premature delivery, stillbirth and congenital malformations. Iodine deficiency in adulthood can lead to hypothyroidism, fatigue, and lack of concentration. We cannot synthesize iodine by ourselves, we can only take it from the external environment. China is one of the countries with the most severe iodine deficiency in the world. The external environment (water, soil, etc.) in most areas of my country is almost deficient in iodine. The iodine stored in the human body can only last for up to 3 months, so long-term iodine supplementation is required. my country began to implement universal salt iodization in 1995 to prevent health problems caused by iodine deficiency. If iodine-free salt is consumed, the iodine intake of more than 97% of residents will be lower than the recommended intake, and residents are at a high risk of iodine deficiency. For non-pregnant people, only patients with autoimmune thyroid disease (commonly hyperthyroidism, thyroiditis, etc.), because of the need for treatment, can follow the doctor’s advice not to eat or eat less iodized salt. How much iodized salt should be consumed daily to meet the standard? During pregnancy, pregnant women must not only meet their own iodine needs, but also provide iodine nutrition for the fetus. Therefore, the recommended intake of nutrients for Chinese residents: the recommended intake of iodine during pregnancy is more than doubled on the basis of the general population, reaching 230ug/day. The WHO recommends that women who are pregnant, gestating, and breastfeeding should ensure at least 250μg of iodine intake per day. Even if there is thyroid disease (hyperthyroidism, thyroiditis, etc.) before pregnancy, after pregnancy, you should consume iodized salt, take iodine supplements, and eat iodine-rich foods while you are instructed by your doctor and monitor your thyroid function. Do not use iodine-free food blindly. salt. It is recommended that all pregnant mothers eat iodine-rich seafood (such as kelp, seaweed, wakame, dried shrimp, etc.) on the basis of iodized salt 1-2 times a week. However, the iodine supplemented by food is not enough to meet the daily iodine intake during pregnancy, and a supplement containing potassium iodide (or a compound nutritional supplement containing the same dose) should be selected for iodine supplementation under the guidance of a doctor. Importance of iodine supplementation Since 2009, the iodine nutrition level of pregnant women has continued to decline in Beijing, and the current pregnant women are at the lower limit of the appropriate range of iodine nutrition. This shows that people are not paying enough attention to iodine nutrition during pregnancy. The main hazard of iodine deficiency disease is irreversible mental development damage, among which the fetal period to 2 years after birth is the most critical period. Therefore, in order to ensure reasonable iodine nutrition for pregnant women and normal fetal mental development, without special medical advice, pregnant women are advised to maintain reasonable iodine intake through food such as kelp and seaweed while maintaining iodized salt. Finally, summarize two points of today’s content: First: eat iodized salt during pregnancy, on this basis, eat 1-2 iodine-rich seaweed, kelp, wakame, and mussels a week; it is necessary to take iodine-containing foods Supplements; Second: If you have thyroid disease before or during pregnancy, you should not take iodine-free salt. Follow the doctor’s advice to take a reasonable intake of iodine to avoid abnormal fetal intellectual development.

Will eating iodized salt make the nodules recur? 5 truths about the thyroid

When there is a problem with the thyroid gland, various problems occur and cause annoyance. Can thyroid nodules eat seaweed laver? Will thyroid cancer relapse after eating iodized salt? When can hoarseness after thyroid surgery be better? Let’s take a look at the professional answers of the doctors together! Can I eat seaweed laver if I have a thyroid nodule? Iodine plays an important role in thyroid disease, too much or too little. Thyroid nodules need not be limited to seafood, depending on the specific situation: if accompanied by hyperthyroidism, you need to avoid iodine, can not eat iodized salt, kelp, seaweed and seafood; if accompanied by Hashimoto’s thyroiditis, you need to limit Iodine, you can eat iodized salt, but eat less kelp, seaweed, seafood; if it is just normal thyroid nodules, you can eat normally, just be careful not to eat kelp, seaweed in large quantities for a long time. Although studies have suggested that excessive iodine may increase the risk of papillary thyroid cancer, too little iodine may increase the risk of follicular thyroid cancer. However, the amount of iodine that we supplement by iodized salt is appropriate, and eating regular kelp, seaweed, seafood, etc. will not cause excessive iodine intake. Only long-term, large-scale consumption of kelp and laver can lead to excessive iodine intake. Therefore, there is no need to specifically change the diet to avoid the above two types of thyroid cancer. Will thyroid cancer relapse after eating iodized salt? This problem can evolve into: Can thyroid cancer eat iodized salt after surgery? If thyroid cancer needs to be treated with iodine 131 after surgery, you should avoid iodine for at least 2 weeks before treatment (some avoid iodine for 4 weeks), and only eat non-iodized salt. The purpose is to make the thyroid gland in the “iodine starvation” state, to better absorb iodine 131, and eliminate remaining cancer cells. If you do not need 131I treatment after thyroid cancer, you don’t need to avoid iodine, you can eat iodized salt. In fact, excessive and insufficient intake of iodine is a risk factor for thyroid cancer. Therefore, patients with thyroid cancer should try to eat as much iodine as possible: if you eat iodized salt, you should eat less iodine foods such as kelp and seaweed; if you eat no iodized salt, you can eat seafood such as kelp and seaweed in moderation. Is Hashimoto’s thyroiditis hypothyroidism? Hashimoto’s thyroiditis ≠ hypothyroidism. There are many causes of hypothyroidism, and Hashimoto’s thyroiditis (referred to as “Hashimoto”) is just one of the most common causes. Hashimoto may not always become hypothyroidism. Hashimoto is a chronic inflammation that gradually destroys the normal function of the thyroid. Some Hashimoto patients will eventually have hypothyroidism, but some lucky Hashimoto patients will not have hypothyroidism for life. Hashimoto is characterized by increased TPOAb and TgAb, and hypothyroidism is characterized by increased TSH. Then, the characteristic of hypothyroidism caused by Hashimoto is that TPOAb, TgAb, and TSH are all increased. At present, Hashimoto is still an “incurable disease”. There are no specific drugs to reduce TPOAb and TgAb, and no specific drugs to prevent Hashimoto from developing hypothyroidism. However, there are a small number of people who may have decreased TPOAb and TgAb after selenium supplementation, so Hashimoto patients can try selenium supplementation treatment. However, it is recommended to supplement selenium under the guidance of a professional doctor to prevent poisoning caused by excessive selenium supplementation. When can hoarseness after thyroid surgery be better? The most common cause of hoarseness after thyroid surgery is damage to the recurrent laryngeal nerve, which causes disturbance of vocal cord movement. The injury of the recurrent laryngeal nerve may be temporary or permanent. 1. Temporary recurrent laryngeal nerve injury is mostly caused by the nerve being stretched or compressed. Damaged nerves can repair themselves. The repair time is related to personal constitution, ranging from a few weeks to a few months, with an average of 3 to 6 months. It can carry out physical therapy and vocal exercises to help nerves repair themselves. If the hoarseness is particularly obvious, you can also take oral methylcobalamin tablets for treatment. 2. Permanent recurrent laryngeal nerve injury is relatively rare, mostly caused by tumor erosion or direct injury from surgery. Damaged nerves cannot fully return to normal. However, the human body has self-remedial measures, and the function of the vocal cords on the normal side will gradually increase to compensate, and the degree of hoarseness will be reduced. This compensation process takes more than 6 months. For permanent recurrent laryngeal nerve injury, surgical treatment may be performed, which may improve the hoarseness of the voice. Can hyperthyroidism be restored? In medicine, hyperthyroid exophthalmos are “thyroid-related eye diseases” (referred to as TAO). TAO has many manifestations, including enlarged eyes, edema of the eyelids, watery eyes (due to conjunctival edema), protruding eyeballs, restricted eye movements, double vision, blurred vision, blindness, etc. regret

Eating salt is also a knowledge! They are all eating, and eating the wrong food may cause thyroid disease!

The saltiness of meals depends on the addition of salt. Many people like to add salt when cooking. Some people ask about eating salt. If you eat too much, it will damage your thyroid! Some people may ask, is n’t the food a bit salty? What harm is high salt? The important part of salt is the important part of salt. Sodium chloride (NaCl), and the main role of sodium ions is to regulate water and osmotic pressure in the body, enhance neuromuscular excitability, maintain acid-base balance and normal blood pressure function. The harm of high “salt value” 1 damage to the throat and thyroid. Eating too salty and spicy food will irritate the throat or thyroid, easily lead to pharyngitis and thyroiditis, and also reduce the resistance of mucous membranes to viruses and bacteria, so in order to protect your own Throat and thyroid, usually try to control salt intake. 2 High “salt value” is closely related to high blood pressure. Excessive salt intake can increase blood pressure and also increase the risk of heart disease and stroke. 3 Slow response. Eating too much salt will make people dehydrated, and dehydration will suddenly reduce the ability to think clearly. A study published in the Journal of Nutrition shows that mild dehydration causes women ’s performance in cognitive function tests that measure attention, memory, reasoning ability and reaction time compared to when there is sufficient water in the body Get worse. In addition, dehydration can make people’s emotions plummet. 4 The younger the age, the higher the “face value” and the greater the harm. For children, too much salt intake is also harmful. A high-salt diet will increase the risk of cardiovascular disease, upper respiratory tract infection, and zinc deficiency in children. 5 Too much salt can cause a variety of health problems such as: obesity, diabetes, stomach cancer, osteoporosis, kidney stones, asthma, etc. It is estimated that if global salt consumption is reduced to the recommended level, 2.5 million deaths can be prevented each year. How do thyroid patients eat salt? Since eating too much salt will cause so much harm, which salt should be better for patients with thyroid disease? According to the amount of iodine, table salt is mainly divided into three categories: iodized salt, non-iodized salt, and low iodized salt. But the salt sold in supermarkets is not limited to these three kinds, it is often eye-catching. Let’s take a look at the difference between them. 1 plus iodized salt plus iodized salt is common salt. The common salt currently on the market generally refers to iodized salt, and the iodine content per 100 g of common salt is 2250.0 μg. The iodized content of iodized salt in different regions may be slightly different. Suitable for people: healthy people without thyroid disease. 2 No iodized salt No iodized salt generally has the word “no iodized salt”, and some supermarkets may not be able to buy it. The nutrient composition table shows that the iodine content per 100 grams of salt is 0 micrograms, that is, no iodine. Appropriate population: patients with thyroid diseases such as hyperthyroidism, thyroid cancer surgery before iodine 131 treatment, thyroid nodules combined with hyperthyroidism & nbsp. & Nbsp. Doctor reminds: not all patients with thyroid problems should eat iodized salt (low iodine diet ≠ eat No iodized salt). Be sure to follow the doctor’s instructions to eat salt, please do not use iodized salt without permission. 3 Low iodized salt Low iodized salt generally also has the words “low iodized salt”, which may not be available in some supermarkets. The nutrient composition table shows that the iodine content per 100 grams of salt is 2000.0 micrograms, which is slightly lower than the 2250.0 micrograms of ordinary salt. Appropriate population: some patients with thyroid disease such as Hashimoto’s hypothyroidism. Doctor reminds: As with iodized salt, whether thyroid patients need a low iodine diet should also follow the doctor’s advice, do not consume low iodized salt without authorization. Experts remind that there are many salt choices on the market such as sea salt, rose salt, calcium salt, etc., but no matter how high-grade salt, its essence is still salt, its main ingredient is sodium chloride, which is essentially a seasoning, It does not meet the body’s more nutritional needs. Patients with thyroid disease should never choose to add iodized salt, and you must follow the doctor’s advice. In addition, when buying table salt, you should also remember to read the ingredients list on the table salt carefully and select the appropriate table salt according to your physical condition.

Hyperthyroidism avoids iodine, hypothyroidism reduces iodine, so what about “thyroid nodules”?

Too much or too little iodine intake will cause an increase in thyroid disease. Because thyroid nodules are not a simple disease, but a general term for a large class of diseases. Therefore, the intake of iodine is more complicated and cannot be generalized. It needs to be distinguished according to the different types of thyroid nodules. With thyroid nodules, how do I consume iodized salt? “If accompanied by hyperthyroidism, iodine diet should be avoided.” Thyroid inflammatory nodules, nodular goiter, thyroid adenoma, thyroid cancer may be accompanied by hyperthyroidism. So after finding nodules, be sure to check the thyroid function. If you have hyperthyroidism, you should strictly avoid iodine diet, that is: eating non-iodized salt, fasting seafood, especially high-iodine seafood such as kelp, seaweed, try to avoid the use of iodine-containing drugs. Because iodine is an essential element for the synthesis of thyroid hormones, intake of iodine will aggravate the condition of hyperthyroidism. At the same time, due to hyperthyroidism, the body is in a high metabolic state and high energy consumption, so you should eat more high-protein, high-calorie foods, drink plenty of water, and avoid strong tea, coffee and other beverages that are easily excitable. “If there is no hyperthyroidism, only a low iodine diet is needed.” Some thyroid nodules may be related to excessive iodine intake, such as Hashimoto’s thyroiditis and papillary thyroid cancer. Therefore, if there is no hyperthyroidism in this type of thyroid nodules, you can eat a low-iodine diet, that is, you can eat iodized salt, but you must limit high-iodine foods, such as kelp and seaweed. “No high iodine diet is generally needed” although some thyroid nodules are related to iodine deficiency, such as nodular goiter and follicular thyroid cancer. However, since the addition of iodized salt, most regions of China have no iodine deficiency problems, so there is no need to eat a lot of high iodine food to prevent the above diseases. Improper diet can further aggravate the condition of thyroid nodules, but if the diet is reasonable, it can help the thyroid nodules recover faster and better. Therefore, thyroid patients should eat iodine food according to their actual conditions, and not blindly eat. # Thyroid # daily question: if thyroid nodules are benign, can you just let it go? A: No matter benign or malignant nodules should be actively treated, otherwise it will cause serious damage to people’s nervous system, reproductive system and daily life. If the nodules rapidly increase in physical examination in a short period of time, they should be highly valued and treated.

Why did you stop jiayoule and strictly ban iodine before the use of iodine 131?

First of all, let’s understand why you should take Ujiale? After all the patients with nail cancer have undergone surgical treatment, most of our thyroid glands have been removed, or even completely removed, then we have fewer thyroid organs than ordinary people. Don’t look at his small size, but it will secrete an important thing called thyroid hormone. This hormone regulates our metabolism and affects the normal work of other organs. More or less will not work, and more will form hyperthyroidism. This At this time, our metabolism will increase, the organs will be overloaded, and people will lose weight and suffer from symptoms such as palpitation, insomnia, and irritability. Without hypothyroidism, we will have the opposite reaction. People are prone to burnout, fatigue, lethargy, and mucous edema, which is also called “fatness.” Surgical removal of our thyroid, we have to take oral supplements, and to add to a subtle state-a little more, but can not reach the level of hyperthyroidism, in this subtle state can inhibit the recurrence and metastasis of nail cancer Magical effect. So, why should you stop Ucaride before 131 iodine treatment? After taking Ucaride, the residual thyroid tissue and possible nail cancer lesions are in a state of inhibition, and there is no response to the doctor’s treatment. In order to make these possibly existing lesions active again, we temporarily stopped Youjiale. Will the remaining lesions become active again, will it relapse or metastasize? Because the time of drug withdrawal is 3 weeks to 4 weeks, in this short period of time, the disease will not recur or metastasize, but it is difficult to say that the drug withdrawal time is long. Therefore, patients who stop taking medicine before iodine 131 treatment should strictly follow the doctor’s requirements. Why do iodine ban before iodine 131 treatment? The thyroid is the only organ in the body that can use iodine in a large amount, and the cancer cells of papillary thyroid carcinoma and follicular thyroid carcinoma still retain the iodine uptake capacity of normal thyroid cells. This is the premise of our use of radioactive iodine 131 against thyroid cancer cells. Under normal conditions, 25% -50% of the iodine ingested by the human body is taken up by the thyroid gland, and in the state of iodine deficiency, this percentage can be increased to 80%, in order to keep the residual thyroid or lesions to maintain a starvation of iodine State, so we have to ban iodine. How to prevent iodine effectively? First, eat iodine-free salt, pay attention to iodine-free salt, not low iodine salt or low sodium salt, the packaging of table salt is marked as iodine-free salt. Second, prohibit the consumption of foods with high iodine content. Foods with high iodine content include seaweed, seaweed, sea cucumber and other seafood. Celery in vegetables contains the most iodine. Various dairy products and eggs are also foods with high iodine content. In order to ensure the baby’s iodine intake, the iodine content in milk is 20 times the iodine content in blood. Third, prohibit taking and injecting iodine-containing drugs. Oral iodine-containing drugs, such as cidi iodine tablets, etc., when patients take drugs during iodine ban, it is best to look at the drug instructions to see if it contains iodine. The injected iodine-containing drugs are mainly some imaging agents. For example, the drugs injected during CT enhanced scanning are iodine-containing. These iodine-containing drugs will seriously affect the therapeutic effect of iodine 131, so special care should be taken!

What should I do if the thyroid TSH value is abnormal during pregnancy?

Because more and more pregnant mothers will check this thyroid function during pregnancy. Then, there will be such a situation that the thyroid function is not normal. Today, the thyroid lecture hall will tell you what to do if TSH is not normal. During pregnancy is a special physiological state. This thyroid stimulating hormone during pregnancy, we said The normal value of the TSH indicator is lower than when it is not pregnant. According to our country’s guidelines In early pregnancy, the normal value of this TSH is from 0.1 to 2.5, which means that it is less than 2.5 before three months, and mid-late period is from 0.2 to 3.0. If the TSH exceeds 2.5 or 3.0! But the thyroid hormone level is normal, we have to diagnose a subclinical hypothyroidism. If this is higher than this index, we need to make a comprehensive judgment. The general doctor will give You see if you have the problem of thyroid antibody. Combined with your gestational week, you will sometimes have an assessment of diet and iodine to understand whether you are short of iodine or too early during pregnancy, and so on. Then, sometimes the doctor will do a regular thyroid function test (for example: every other week). If your urine iodine is not enough, it means that your iodine intake is insufficient. It is recommended to eat kelp, seaweed and iodine. Salt, even pregnant women’s iodized salt to increase the level of iodine, so that we can see if the thyroid function can be adjusted to normal. If TSH is increased, not due to insufficient iodine intake, it is due to other chronic thyroiditis autoantibody problems, then the mainstream is still recommended to choose levothyroxine tablets (also known as Urothal), or Retix instead of treatment For these two drugs, we say that he is basically consistent with your physiological secretion of thyroid hormones, so it is very safe. However, after treatment, it is generally necessary for the doctor to look at the level of thyroid hormones every week to adjust the dose. If it is suitable, it is good to avoid or use too much, resulting in an stimulating hyperthyroidism! It is still very important.
