Endemic goiter, growth retardation and other children's diseases caused by iodine deficiency has been left to the people the pain of a lifetime to make people aware of the dangers of iodine deficiency. Thus, universal iodine, as a state policy implemented since 1994, followed by salt, iodine and other iodine-containing soy foods fast all households. But recently, online rumors about the "excessive iodine intake disease," post, so eat more than ten years of iodine-containing foods, iodine deficiency has long been out of embarrassing people once again trapped in a "iodine storm."
Iodine deficiency iodine, sounds reasonable, but everything particular about a degree, the same iodine, iodine supplement more equally harmful to humans. In recent years, admitted to a number of major hospitals in our province because of excessive iodine intake Erzhi goiter patients. Endocrine and thyroid specialists believe that this long-term consumption of iodine-containing foods and the people are. Members of the public confused: In the immediate living environment, how can we prevent iodine thyroid disease, thyroid nodules and thyroid cancer What is the difference? Recently, this reporter interviewed with these problems large and medium-chi, director of endocrine-Japan Friendship Hospital, Wang.
Deputy Director Wang said the normal structure of thyroid nodules are thyroid abnormalities occurred. As the living conditions and dietary habits change, the decline in their immune system and many other factors working together, China's current number of people suffering from thyroid nodules there is indeed a rising trend.
Scientific diet to prevent iodine thyroid disease
With the improvement of living standards, people not only among the intake of iodine from salt, seafood and other seafood, and grown in iodine-rich soil in the vegetable ingredients are also a lot of iodine. World Health Organization designated the human iodine intake of 150 micrograms / day is safe, and long-term complications of excessive iodine can lead to the emergence of iodine. Wang said that if a person's diet in the same environment have emerged in abnormal thyroid swelling or nodule, should first consider whether the eating habits of science, according to the doctor's advice to improve the diet. Iodine content in food animal foods than plant foods, fruits and vegetables, low iodine content. In addition, the iodine case of acidic substances will be destroyed. Therefore, the cooking time add the right amount of vinegar, iodine consumption rate can be reduced by 40% - 60%. Eat soy products. Soy contains a variety of saponins, saponins easily lead to both prevent arteriosclerosis and aging of the lipid peroxide production, can inhibit the absorption of fat and promote fat break down. In addition, saponins also has a row of iodine effect.
Most thyroid nodules do not need an operation
Professor Wang, currently a common thyroid nodules, including thyroid hyperplastic nodule cyst, tumor nodules, cystic nodules and inflammatory nodules four. The formation of the majority of thyroid nodules, the patient no special feeling, it is usually in the examination process was only a doctor suggested that only the nodule is large, patients who are easy to find touch.
Many patients have thyroid nodules that their own, the pressure is very large, that had cancer, they immediately went to a doctor for surgery of thyroid Division requirements. However, according to clinical investigation in recent years, the report showed that 95% were found to have thyroid nodules as benign lesions. Part of the patient's nodules can be self-limiting, while a number of inflammatory nodules, the patient as long as directed by your doctor to improve their living habits, taking drugs, the nodule will be significantly reduced. Therefore, even if occurring thyroid nodules found themselves need not be unduly alarmed, but in time to the hospital for treatment and regular follow-up is very necessary. Recommendations for patients with nodules, every six months or a year do a thyroid ultrasound examination, if necessary, biopsy cytological examination can be carried out.
Doctors do not advocate blind patients in surgery, removal of nodules Another important reason is that taking into account the difficult thyroid surgery. Location of peripheral vascular abnormalities of thyroid-rich, and are more involved in the organ, the patient surgical procedures have been accidentally injure blood vessels or nerves of the risks, which would result in irreversible consequences for the patient. In addition, if the thyroid were cut too much, can lead to postoperative hypothyroidism symptoms occur, affecting their health.
Thyroid cancer to determine a standard
To determine whether suffering from thyroid cancer, Wang, director of listed seven basic criteria. 1. Patient's age. Under normal circumstances, 20 years of age and 70 years old is a high incidence of thyroid cancer in two stages. 2. Patient's gender. Thyroid cancer in a male patient majority. 3. Ill family history. Because thyroid cancer have a certain genetic predisposition, so that if any immediate family members of patients with thyroid cancer, other family members should be classified as high-risk groups. If these people abnormal thyroid nodules should be a high priority. 4. The head and neck radiation therapy had history. 5. Nodule growth rate, activity. If the nodules developed rapidly in the short term, and difficult activities, they should promptly requested medical attention. 6. Caused by the trachea and other local organs of oppression, there swallowing, pronunciation difficulties. 7. Regional lymph nodes. Thyroid cancer invasion and foci can be transferred around and make it swollen lymph nodes.
Typical thyroid cancer can be through a professional diagnosis of thyroid ultrasonography, the condition can also be complicated by fine needle aspiration cytology of thyroid tumor biopsy to determine the nature of. Currently, surgical resection of lesions is still the preferred method of treatment of thyroid cancer. If early detection of thyroid cancer and receive regular treatment, the prognosis for long-term survival rates higher than the other types of cancer.
How to prevent the occurrence of thyroid disease, Deputy Director Wang believes that the public must pay attention to routine physical examination. After 20 years of age should do a thyroid ultrasound examination every year for a family history of high-risk groups should be closely monitored, preferably once every six months follow-up examination. At the same time, regulate the pace of life, maintaining emotional stability. Enhance immunity and reduce infection.

Will thyroid nodules turn to cancer?
Thyroid in recent years, more and more sudden, static and dynamic, becoming an obsession with youth problems. In particular, thyroid nodules, not only the incidence rate had risen sharply, but also because, and thyroid cancer are inextricably linked, causing people's vigilance.
Thyroid nodules, and multiple single points, more common in middle-aged population, a high incidence in the 30-50 year-old woman.
The reason why increasing incidence, in addition to and the environment, diet-related, the mental pressure, infection, stimulation, fatigue, trauma and so may become a temptation. Fortunately, however, that, although the high incidence of thyroid nodules, but the vast majority are benign.
But that is not to say there is no thyroid nodules and thyroid cancer associated with, the former is still an important inducement for the latter, there are several conditions should be wary: 1. A single nodule than the risk of multiple nodules; 2. A rigid, fixed not painful, nodules; 3. nodules grow rapidly; 4. there is a tiny calcification spots; 5. goiter, a swollen lymph node near the same time; 6. Having enough thyroid inhibitors 2-4 months, nodules were not reduced but increased; 7. thyroid nodules cause significant pressure symptoms or hoarseness persons; 8. thyroid scan an individual appears "cold nodules" have.
For the multiple thyroid nodules, can be reviewed on a regular basis. In the meantime, if the nodule size increases rapidly in a short time, we should pay great attention to the treatment, while the solitary pulmonary nodule is the best surgery. Diameter of more than 1 cm thyroid tumor, even if a benign clinical considerations, but also recommended early surgery to prevent cancer.

Breast, thyroid cancer calcification of alert signals
Film go to the hospital examination, often encountered such a situation, the doctor later pointed to the film will be somewhere on the strong points of light to tell you that there is a slight calcification.
Most people have heard of this word, it may not be too nervous, just a few small bright spots Well, what relationship? And then ignore it, I did not expect, after a period of time check, it had torn cancer. What is the reason for this?
In fact, the calcification is the most common breast imaging is one to do breast X-ray examination, will be able to find this unusual. Statistics show that 65% of breast cancer calcification, 70% of malignant calcification. Which is the early detection of relatively hidden, and relatively small breast cancer a good way. If there is calcification of the surrounding structures concurrent disorder, bilateral asymmetry, thickening and other signs of vascular shadow, then the malignant lesions is more likely. In short, whether or not there are lumps, calcification was found should be immediately asked to give further diagnosis of cancer specialists, and timely surgery.
Thyroid gland is another notable place. Less calcified benign thyroid diseases to emerge, once the thyroid gland calcification occurs, while the spot of strong and large, it is recommended to do puncture pathology investigation to determine whether the tumor. In general, benign thyroid relatively coarse calcification images more clear edge; while malignant tumor is the shadow of light and fuzzy.
Comparison of prostate and lung are also prone to calcification in place. The former is prostatitis healed scars, and some prostate stones, without treatment. But considered that calcification of the lungs are also benign lesions, this is a serious misunderstanding. On the basis of the calcification of lung cancer is entirely possible, especially those X-rays show calcification of the patients at the same time there is airway obstruction, it is necessary and timely inspection, clear lesions, and surgery when necessary and timely.

City Union Medical College Hospital successful implementation of endoscopic thyroidectomy
Bohai Sea News Network news recently, General Surgery, Union Hospital, city, using endoscopic technology, one female patients with ultrasound hemostasis in endoscopic resection of thyroid tumors knife, the patient did not leave the neck a long tradition of open surgery, "centipede scar" .
The 24-year-old female patient is a music teacher, long ago voice a bit hoarse, mistaken for occupational diseases, often with throat piece has been not improve. Look in the mirror when you stumbled on the neck a little bit of local processes, then went to a hospital. After careful examination, the doctor said that thyroid objects that need surgery, otherwise they will get bigger, there will be the possibility of cancer, according to the traditional surgical method, even if the use of "beauty line" to do intradermal suture, also in the neck leave a linear scar. As she hesitated, the city of General Surgery, Union Hospital, director of Chen Tieliang to her being carried out, introduced a new type of thyroid surgery, that patient through the chest area or areola only cut the size of three soybean incision to complete the neck of the thyroid surgery, postoperative neck, leaving no scars, but also safe and reliable operation. Thus, the patient underwent surgery with pleasure.
According to Chen Tieliang doctor, at present 50% of people who have small nodules, of which 4% to 10% rate of malignant thyroid tumor is a thyroid disease, the incidence rate of about 30%. Therefore, a majority of thyroid nodules are found, they should be the early surgical treatment. The traditional thyroid surgery in the neck and leaves 6-10 cm long surgical scar. How to miniaturized surgical incision and transferred to a more secluded location, is currently the best surgical approach is endoscopic thyroid surgery.

Is Iodized salt the cause of thyroid disease culprit?
August 12, in some areas, "iodine excess" leads to an increase of thyroid disease, saying the Ministry of Health said, "thyroid cancer and salt iodization in the" lack of evidence to say, but the next year, China will appropriately cut the amount of the existing salt iodization.
"Iodized salt" storm while temporarily come to an end, but the city often accompanied by members of the public side of the daily salt attention, has not been reduced. Recent edition "doctor-mail" often received some readers call to ask Jinhua suffering from thyroid disease, the Advisory If you want to reduce iodine content in salt should be how to do? Where can I buy non-iodized salt needs of special populations?
Reporter Xiao-Yun Xu
Wu, urban readers a day before yesterday said that they conduct an annual medical examination of workers were organized, because he suffers from diabetes, and attached great importance to the annual physical examination. Last year, physical examination, he was not found to have thyroid nodules, and this year only to find the three physical examination, some doctors said that his need for surgical treatment of thyroid nodules, but some doctors that there is no surgical treatment, which left him difficult, do not know how to do? Because he suspected he was suffering from thyroid nodules with the "excess iodine" relevant, so the day before he went to the supermarket to buy "non-iodized salt," eating, he was almost running all over the city of Jinhua in all supermarkets, but they did not sell. He said that could help him to ask Jinhua Where can I buy "no salt"?
Yesterday, a reader called the urban area, said one of his classmates, as with thyroid cyst excision was done two years ago, he was very worried that she would suffer from this disease, he asked Jinhua suffering from thyroid disease there were many people suffering from thyroid disease, what with the "iodine excess" has nothing to do with?
Department of Endocrinology, Central Hospital, Jinhua, director, chief physician Hu Su-Yin said that in the country does not promote consumption of iodized salt prior to the city's goiter (commonly known as big neck disease) were more prevalent, and swelling are generally more serious, since the taking iodized salt, the kind of patient is very rare, with iodized salt in prevention of thyroid disease, it can be said to go up.
HU Su-Yin said that from Jinhua Central Hospital out-patient situation, the city is now suffering from thyroid disease than in patients who have increased, particularly in patients with hyperthyroidism. But the cause of thyroid disease for many reasons: because iodine is the synthesis of thyroid hormone as a raw material, so long-term excessive intake of iodine can cause; a faster pace of modern life, the pressure had caused the General Assembly; exertion, trauma, pollution and environmental factors were also cause. Therefore, for the city in recent years an increase in thyroid disease patients who have no relationship with the consumption of iodized salt, it's hard to say.
Jinhua Guangfu Hospital, Surgical Oncology Director, Chief Physician ming dynasty, from the hospital to patients in Kwong Fuk see, Jinhua suffering from thyroid cancer patients than in the past a number of previously encountered only 12 cases a year, but now a month will encounter 12 cases, the growth rate is indeed faster. Thyroid cancer and the relationship between iodine intake may be a bit too much. Because there is no contrast material, has not conducted research, as Jinhua suffering from thyroid cancer patients than in the past with the consumption of iodized salt has nothing to do with, can not be conclusive.
Jinhua reporter visited the day before yesterday, found that the major supermarkets, supermarkets do not sell non-iodized salt, while the hyperthyroid patient is definitely not consumption of iodized salt, then what Jinhua Where can I buy non-iodized salt do? This reporter called the Jinhua Salt Company, Salt's wholesale department staff surnamed Fu said that in order to ensure the general population iodine intake, there are provisions above, non-iodized salt is usually not enter the supermarket sales, for the suffering Thyroid disease can not consume iodized salt to buy non-iodized salt, if special populations, can be set up in their company, Jiangxi Road, Wu-monopoly point Yancang Lane purchase, purchase to be issued by the doctor's prescription or proof.
HU Su-Yin said that if the people concerned about their intake of iodine excess, you can own at home through a number of tips to "reduce iodine treatment." Of iodized salt can be poured into clean, dry and slightly heated pot duplicating the few, the iodine content of iodized salt will be reduced. Of iodized salt can also be stored off Cap 2 to 3 days, the iodine in salt will also be part of the volatile off. Drying under the sun to get iodized salt, iodine would evaporate away.
Non-smooth texture hardware may be cancer
Ming dynasty, thyroid disease, there are many, in addition to hyperthyroidism and thyroid cancer, there are thyroid cancer, thyroid nodules, thyroiditis, thyroid cyst. For thyroid nodules, iodine deficiency in the human body, or would give rise to excessive iodine intake, the patient what is required or prohibited iodine supplementation of iodine intake, this needs to be known isotope scan. As far as he understood that at present there is no such inspection equipment Jinhua, Hangzhou, Zhejiang is located in a hospital, Sir Run Run Shaw Hospital equipment definite diagnosis by the hospital. Dynasty noted that it is suffering from thyroid cysts and nodules where bleeding because the bleeding caused by thyroid nodules where the probability of cysts are relatively high.
Suffering from thyroid cancer surgery or not? Ming dynasty, for solitary thyroid tumor, hand-to-mass is not smooth, texture rather hard, the possibility of cancer is greater; the age of fourteen or fifteen years, the possibility of malignant relatively large; B-ultrasound and found that knot section, there are blood vessels, the probability of cancer is relatively large; B ultrasonic examination found that the edge of a small calcified nodule point, the possibility of malignant is relatively large. To do this for the solitary thyroid tumor, suspected to be malignant, requiring surgical removal and biopsy to diagnose. For the thyroid nodule, if the nodules in two centimeters, and can be observed on a regular basis, no surgical treatment, if the nodules in two centimeters or more, then needed surgery to prevent malignant transformation. Ming dynasty, one side of the thyroid gland removed, they have much influence on the body. If the sides are removed, an impact on the human body needs to supplement thyroid hormone. If there is no hormone human face appears swollen, general weakness.
Ming dynasty, thyroid cyst Although most are benign, but if the cyst grows to 56 centimeters big, but also removed, otherwise they will get bigger, and even compression to the trachea, will bring more difficult surgery.

Is there evidence about "Iodized salt carcinogenic"?
Recently, the "salt disease" has become the hot topics under discussion. Although the Ministry of Health to respond to, "thyroid cancer and salt iodization in the" lack of evidence to say, the public is still not feel safe. Well, so what's the relationship between iodine and thyroid whether it?
Essential trace elements in the human body, none of which, like iodine, like, with an organ called the thyroid gland so closely. As the body's largest endocrine organ, the thyroid can secrete thyroid hormone synthesis, which is the main raw material for iodine. A variety of thyroid hormone can regulate the body metabolism to maintain cell life activities; can promote infant growth and development, the lack of will lead to "cretinism" and mental retardation, excessive secretion would cause hyperthyroidism, commonly known as "hyperthyroidism."
It is interesting that iodine intake may affect the amount of thyroid hormone secretion. In other words, thyroid enough squeamish, too high or too low iodine, may cause abnormal thyroid function, iodine intake is too low will lead to iodine deficiency diseases, prevention of salt iodization is it; excessive iodine intake may be related to thyroid The increase in diseases related. (According to reader feedback, and find the relevant medical literature, the original sentence "excessive iodine intake can lead to increase in thyroid disease." Changed to "excessive iodine intake may be related to an increase in thyroid disease are related," a more cautious view of science )
Thyroid cancer can be divided into four kinds, the most common is papillary carcinoma and follicular thyroid cancer, the former accounting for 60%, was low-grade, common in young women, who account for about 20%, moderate, middle-aged multiple malignant . They relate to the relationship between iodine intake is also a medical profession a long-term hot-academic topic. Many countries have research on this, but geography, race, diet characteristics, the supply of iodized salt by factors such as differences in the results of the report is not entirely the same.
In 1977, the United Kingdom Williams, Welsh National School of Medicine physicians in Iceland and the United Kingdom Aberdeenshire done an investigation. The results showed that papillary carcinoma and follicular thyroid cancer incidence rates would be the impact of dietary iodine, iodine intake area more than papillary carcinoma occur. United States Northern California Thyroid Cancer Research Center, told the San Francisco Bay Area in 1995 -1998 years, suffering from thyroid cancer in women in an investigation. Results On the contrary, iodine intake increased, with the incidence of papillary thyroid cancer risk reduction associated with.
The study did not fully answer whether the amount of iodine intake affect the incidence of thyroid cancer. In August of this year, "hormone" magazine published an overview. By a detailed review of the past 30 years worldwide on the relationship between iodine and thyroid cancer by the study. He pointed out that, according to the current outcome, an iodine deficiency region the occurrence of follicular cancer, high risk, high iodine intake area higher the risk of papillary carcinoma. Note that this only that specific subtypes of thyroid cancer, the ratio changes, such as iodine intake increases the incidence of papillary carcinoma will be a marked increase in the incidence of follicular cancer would be reduced.
Of course, this result does not mean that excessive intake of iodine can cause papillary carcinoma, follicular thyroid cancer, had as little cause. The relationship between them remains to be further studied. Smith concluded that the incidence of thyroid diseases around the world continue to rise, is an indisputable fact, but there is no sufficient evidence to prove that iodine intake may affect the incidence of thyroid cancer.
In China, iodine and thyroid disease research, the most famous experts in course ought to Teng Weiping, China Medical University, Professor. In 2006, its leadership team published a study on the Liaoning winding (mild iodine deficiency), Liaoning Zhangwu (super-sufficient quantities of iodine) and the Hebei Huanghua (iodine excess) a total of 3761 residents, conducted a five-year epidemiological investigations. It was found that super-sufficient quantities of iodine and iodine excess could induce and promote hypothyroidism and autoimmune thyroiditis the occurrence and development. He further pointed out that the high incidence of thyroid cancer in iodine regional phenomenon worthy of further study.
We have to eat do not eat iodized salt in the end? In Europe, the issue of whether the consumption of iodized salt in most countries people with their own right to choose. For people in Taiwan, it is imperative to increase non-iodized salt or the market supply and distribution points, so that people have a right to choose. No definitive answers for the "salt disease", said to proceed with organizing a large-scale epidemiological surveys and prospective studies, and perhaps give us a clearer answer.

He pointed out that, according to the current outcome, an iodine deficiency region the occurrence of follicular cancer, high risk, high iodine intake area higher the risk of papillary carcinoma. Note that this only that specific subtypes of thyroid cancer, the ratio changes, such as iodine intake increases the incidence of papillary carcinoma will be a marked increase in the incidence of follicular cancer would be reduced.
Of course, this result does not mean that excessive intake of iodine can cause papillary carcinoma, follicular thyroid cancer, had as little cause. The relationship between them remains to be further studied. Smith concluded that the incidence of thyroid diseases around the world continue to rise, is an indisputable fact, but there is no sufficient evidence to prove that iodine intake may affect the incidence of thyroid cancer.
In China, iodine and thyroid disease research, the most famous experts in course ought to Teng Weiping, China Medical University, Professor. In 2006, its leadership team published a study on the Liaoning winding (mild iodine deficiency), Liaoning Zhangwu (super-sufficient quantities of iodine) and the Hebei Huanghua (iodine excess) a total of 3761 residents, conducted a five-year epidemiological investigations. It was found that super-sufficient quantities of iodine and iodine excess could induce and promote hypothyroidism and autoimmune thyroiditis the occurrence and development. He further pointed out that the high incidence of thyroid cancer in iodine regional phenomenon worthy of further study.
We have to eat do not eat iodized salt in the end? In Europe, the issue of whether the consumption of iodized salt in most countries people with their own right to choose. For people in Taiwan, it is imperative to increase non-iodized salt or the market supply and distribution points, so that people have a right to choose. No definitive answers for the "salt disease", said to proceed with organizing a large-scale epidemiological surveys and prospective studies, and perhaps give us a clearer answer.
Thyroid disease will be included in the scope of monitoring of iodine nutrition
For the recent spate of salt iodization policy of our different voices and the general public on the "iodine excessive" concern, September 3, Chinese Medical Association endocrine Credit will be issued an official statement that the policy can not be canceled iodine, but the implementation of the "classification guidance and specific "science iodine supplement policies to enhance the monitoring of all the people of iodine nutritional status.
The Chinese Medical Association, director of endocrine credits member of Ruijin Hospital, Shanghai Jiaotong University said Professor Guang Ning, vice president of the Chinese Medical Association endocrine credits will act as my thyroid disease-related clinical professional bodies, on the current policy of holding our three points of iodized salt:
- Iodized salt is now internationally recognized as the best method of iodine supplementation should be adhered to. Iodine deficiency due to lack of resources, natural iodine, are generally not self-healing. Therefore, iodine deficiency has been identified as areas must adhere to the policy of sustained iodine.
- Suggested that the state implement the "scientific iodine, guidance, specific" approach iodine supplementation. Salt departments should be based on the provinces, autonomous regions and municipalities to develop policies and local residents of iodine supplementation of salt habit, the production of different iodine content in iodized salt for the procurement of parts. Thyroid disease, while ensuring market supply in patients with non-iodized salt.
- To strengthen the country's inhabitants of the iodine nutrition status monitoring, implementation monitoring of the institutionalized, standardized and open. Iodine nutrition status surveillance not only to monitor the urinary iodine concentration of iodized salt in iodine concentration, goiter prevalence, but also monitoring of thyroid disease (hyperthyroidism, hypothyroidism, autoimmune thyroiditis, thyroid nodules, thyroid cancer, etc.) the incidence of changes.
The experts recommended the establishment by the endemic diseases, endocrinology, and the salt industry sectors to participate in the monitoring organization, regular exchange of information, timely change in policy to establish a comprehensive, standardized, rigorous, accurate, and timely monitoring system.

Iodine deficiency and iodine excess are both not good
Expert views
The Ministry of Health next year, the appropriate amount of reduction current of iodized salt, according to local conditions, and appropriate guidance, science iodine. So how do we iodine in daily life more scientific? Iodine, thyroid and thyroid disease, and how is each affected? Shanghai Jiao Tong University Sixth People's Hospital Department of Endocrinology, Li Ming, deputy director of Physicians for this clear up doubts.
Q: Why do we need the body of iodine?
Answer: Iodine is an essential trace element, one involved in thyroid hormone synthesis. Thyroid hormone on human growth, development, protein synthesis, tissue differentiation and energy metabolism plays an important role, and enhance the excitability of the nervous system.
Q: one day need to be supplemented iodine?
A: The Chinese Dietary Reference Intakes provided for adults suitable for daily intake of iodine is 150 micrograms, pregnant women and lactating women is 200 micrograms per day, tolerable upper intake level of 1000 micrograms per day. Main sources of iodine are seaweed, seafood and so on.
Q: Iodine What is the impact on the human body?
A: Iodine deficiency may promote thyroid hyperplasia feedback manner, leading to suffer from goiter. Severe iodine deficiency, may suffer from hypothyroidism. The intention of adding iodine in salt is to combat iodine deficiency disorders such as endemic goiter, cretinism, etc., to prevent the "big neck disease" and to improve children's IQ has been a sense of universal iodine supplementation of the two arguments.
Q: Why is iodine deficiency and iodine can lead to goiter?
A: The epidemiological data indicate that iodine deficiency and iodine goiter rate will be higher when the crowd when the urinary iodine "45 mg / day, goiter and urine iodine is inversely proportional to; as urinary iodine" 1000 micrograms / day , goiter and urine iodine into a positive correlation, showing U-shaped curve.
Q: hyperthyroidism in patients with iodine to bogey do?
A: hyperthyroidism patients must pay attention to food and drink bogey iodine, avoid eating seafood, such as: kelp, seaweed, jellyfish, seaweed, sea fish and shrimp, etc., preferably non-iodized salt consumption.
Q: What are the long-term intake of iodine excess will be harmful? Cause cancer do?
A: In addition to long-term intake of excessive iodine can occur with hyperthyroidism, but also can occur hypothyroidism, Hashimoto's thyroiditis and other hazards. Due to the occurrence of cancer by a combination of factors, at present there is no convincing evidence that excessive iodine and causal relationship between cancer.

Is iodized salt good or not?
According to "Beijing News" reported recently, the "salt disease" has become the hot topics under discussion. Although the Ministry of Health responded: "thyroid cancer and salt iodization in the" lack of evidence to say, the public is still not feel safe. Well, so what's the relationship between iodine and thyroid whether it?
As the body's largest endocrine organ, the thyroid can secrete thyroid hormone synthesis, which is the main raw material for iodine. A variety of thyroid hormone can regulate the body metabolism to maintain cell life activities; can promote infant growth and development, the lack of will lead to "cretinism" and mental retardation, excessive secretion would cause hyperthyroidism, commonly known as "hyperthyroidism."
In China, iodine and thyroid disease research, the most famous experts in course ought to Teng Weiping, China Medical University, Professor. In 2006, its leadership team published a study on the Liaoning winding (mild iodine deficiency), Liaoning Zhangwu (super-sufficient quantities of iodine) and the Hebei Huanghua (iodine excess) a total of 3761 residents, conducted a five-year epidemiological investigations. It was found that super-sufficient quantities of iodine and iodine excess could induce and promote hypothyroidism and autoimmune thyroiditis the occurrence and development. He further pointed out that the high incidence of thyroid cancer in iodine regional phenomenon worthy of further study.
For people in Taiwan, it is imperative to increase non-iodized salt or the market supply and distribution points, so that people have a right to choose. No definitive answers for the "salt disease", said to proceed with organizing a large-scale epidemiological surveys and prospective studies, and perhaps give us a clearer answer.

Reflection iodine excess: to provide the basis for scientific iodine
This is a scientific research, academic valuable, relevant speeches and writings in the impact factor of up to 51 internationally renowned "New England Journal of Medicine" on; the results of scientific research in practical applications affecting the lives of every one of us had to adjust salt iodization as a national standard of one of the scientific basis.
Not long ago, the results of removal of the 2008 National Science and Technology Progress Award second prize, winning the title is "excessive iodine epidemiological and experimental studies."
Recently, the reporter approached the subject of researchers to listen to their retrospective study of history. This reporter can not help but feel that in China and the international effort to combat iodine deficiency in the process, inseparable from the scientific method and scientific attitude.
Iodine intake and thyroid disease was U-shaped relationship is too low or too high can lead to increase in thyroid disease
When we put a plate on the table every day in color, flavor and taste of the food dish, whether conscious, food pan before adding a teaspoon of salt which will be closely related to our health because it contains a known iodine substances.
"Iodine is an important element in nature, for the human body, it is a synthetic thyroid hormone thyroid an important raw material, so the changes in iodine intake, the main impact of thyroid disease." Endocrine Research Institute, China Medical University, the National Thyroid Teng Weiping, head of school said. Iodine deficiency will lead to endemic goiter, endemic cretinism. Curtin patients with severe mental retardation, known as "cretinism."
Since 1990, the International Organization of recommended prevention and control of iodine deficiency disorders worldwide to implement a universal salt iodization, to be in 10 years, the global elimination of iodine deficiency disorders. China is a high incidence of iodine deficiency disorders in the country, since 1996 the implementation of salt iodization in China's legislation in the country, China's population increased dramatically the amount of iodine intake, median urinary iodine (indicating the level of iodine nutrition in the body of indicators) from the 1995 meeting iodine 165 before the μg / l in 1999 rose to 330 micrograms / liter. Iodine deficiency disorders have been effectively controlled, but at the same time, doctors across the country have reflected the endocrine, hyperthyroidism, hypothyroidism, thyroiditis and thyroid nodules and other thyroid diseases, the incidence of significantly increased.
After the residents of universal salt iodization in iodine intake safe? A population of 1.3 billion related to the health issues facing academics and endemic in our endocrine academic front.
At that time the international community has not the concept of excess iodine, international efforts to combat iodine deficiency disorders authoritative organization said: "The daily intake of 1000 micrograms of iodine from a medical sense is still safe. Universal salt iodization in areas of iodine deficiency is not only beneficial to the crowd, and the of iodine sufficient populations are no side effects. "
Professor Teng Weiping access to an extensive literature and found that universal salt iodization mandatory measures, mainly in the developing countries. When the world's developing countries, rapid population increase in iodine intake, when preached by the world's developing countries, developed countries, iodine intake, high intake of low-strange phenomenon. Developed countries in Europe the median urinary iodine is always kept at 70 micrograms / l to 130 mg / l, 65% of the population is iodine deficiency state, residents in most countries the voluntary consumption of iodized salt. Europe is the international minimum iodine intake areas. U.S. residents in iodine intake from the 20th century, 70 years of 320 μg / l down to 90 years to 145 μg / l, the U.S. government has not added any interference.
The exchange of experts, with Europe and the United States, they point to Teng Weiping found the answer: iodine nutrition status is a kind of ecological environment for human survival, to artificially change the ecological environment should be very cautious. Iodine intake by no means the better. Teng Weiping vividly the iodine intake and thyroid disease, the relationship between the metaphor of a U-shaped curve, that iodine intake is too low and too high will lead to an increase in thyroid diseases.
International for the first time a large sample epidemiological studies confirm that excessive iodine can cause thyroid disease increased exponentially
For an accurate picture of iodine intake and thyroid disease, the relationship in 1999, in the USA and China National Natural Science Foundation and the Medical Foundation, funded by the China Medical University, led by Professor Teng Weiping endocrine research group started by iodine-induced thyroid disease epidemic science research and experimental studies. The researchers in Liaoning Province and Hebei Province have chosen mild iodine deficiency (103 mg / l), iodine super-sufficient quantities (376 micrograms / l) and iodine excess (614 μg / l) three rural communities, the survey 16287 people, sample 3761 people, compared to observe the 3761 residents of the prevalence of thyroid disease, morbidity, and disease spectrum of changes, follow-up rate of 80.2%. This is currently the international community about the impact of iodine excess on thyroid largest and most systematic epidemiological study sample.
Of this ongoing five-year survey, clinical hypothyroidism and subclinical hypothyroidism prevalence increases with increased intake of iodine. Super-sufficient quantities of iodine and iodine excess communities, the prevalence of clinical hypothyroidism was 3.2 times and 7.3 multiplier showed a high prevalence of subclinical hypothyroidism showed 3.2-fold and 6.6 multiplier high incidence of subclinical hypothyroidism showed 11.3 times and 12.6 double high. Clinical hypothyroidism and subclinical hypothyroidism is mainly due to autoimmune thyroiditis. Super-sufficient quantities of iodine and iodine excess communities, the prevalence of autoimmune thyroiditis presented 10 times and 15 double high, the incidence rate of 4.5 times and 5.6 showed a high multiplier. Water-iodine communities, the incidence rate of thyroid cancer 19.37/10 10000, significantly higher than the 4 / 10 million to 6 / 10 million, the level of an international disease.
They were also a clinical epidemiological investigation to observe the 610 pregnant women found to increase iodine intake will promote the occurrence of postpartum thyroiditis.
At the same time, the research group to conduct laboratory research results. They prepared an animal model of chronic iodine excess, from the cellular ultrastructure, apoptosis, oxidative damage, genetic susceptibility, autoimmune and other aspects of study of the mechanism of iodine excess. In 2006, Teng Weiping papers such as "China's iodine intake on thyroid diseases impact" published in the "New England Journal of Medicine" on. This is the international impact of iodine excess on thyroid disease, the first prospective epidemiological study by the international medical community's attention.
Salt iodization countries to develop national standards be revised strategy for science and iodine
In 2000, the Ministry of Health held control of iodine deficiency disorders and iodine excess symposium, Teng Weiping system, reported on his 1999 cross-sectional study was first proposed by the implementation of universal salt iodization should be control over the population iodine intake within safety limits proposal. In March 2001, at the Fourth Session of the Ninth National People's Congress, as a deputy to the NPC Teng Weiping lead up to 9000 words submitted a motion, proposed to amend the universal salt iodization legislation. The motion by the State attaches great importance to the timely amendment of the salt iodization relevant national standards. Prevention and treatment of iodine deficiency disorders in the same year, the State proposed the "local conditions, guidance, science and iodine," the new approach. In 2005, the countries to stop the supply of iodized salt in iodine area. According to the National endemic sector monitoring report 2005, China's population median urinary iodine had fallen to 246 mg / l, out of excess iodine status.
Since 2000, Teng Weiping professors and their research group worked in the 12th International Thyroid Conference, the Fourth Conference of thyroid, Japan and South Korea, the Second International Conference on endocrine China, the 13th International Thyroid Congress, the report of China's iodine -induced thyroid disease epidemiology and experimental studies. Danish scholars, Hungarian researcher, also reported on their findings of iodine excess hazards. In a strong appeal to many scholars, the international authoritative organizations combating iodine deficiency has been a fundamental change in perspective. In 2002, the international efforts to combat iodine deficiency was first introduced to evaluate the authority of the Organization of iodine nutritional status of the epidemiological criteria. This standard was first proposed by iodine excess that the definition of median urinary iodine of more than 300 mg / L as iodine excess. They pointed out that in the interpretation of these standards: "In general, iodine intake should not be encouraged more than 300 μg / l, especially in areas of iodine deficiency in the original. Because excess iodine can cause adverse health effects, including iodine-induced thyroid function hyperthyroidism and autoimmune thyroid disease. "
"Science is a benefit of iodine supplementation in people's actions, in our country in the process of elimination of iodine deficiency contributed." Teng Weiping that the elimination of iodine deficiency disorders in the future should continue to adhere to the scientific strategy of iodine must be adapted to local conditions, for different areas, different groups take different iodine dose, strengthen the monitoring, classification guide, so that good things do. "This is a concrete manifestation of the scientific concept of development."
Not long ago, the results of removal of the 2008 National Science and Technology Progress Award second prize, winning the title is "excessive iodine epidemiological and experimental studies."
Recently, the reporter approached the subject of researchers to listen to their retrospective study of history. This reporter can not help but feel that in China and the international effort to combat iodine deficiency in the process, inseparable from the scientific method and scientific attitude.

White-collar pressure to beware of hyperthyroidism
A healthy body is that each of us a better life, work and learning, and is the most important prerequisite for doing anything. Health needs are optimistic and cheerful attitude towards life, while health is good from our everyday habits. Life at home Xiaobian for you a selection of some health health knowledge, health tips to help you better and more scientifically conditioning your body, healthy and happy to spend every day!
Hyperthyroidism "love" in young women, especially white-collar women. According to experts, the current incidence of hyperthyroidism has been 10 years ago 1% to 2%, of which 80% of the patients as a middle-aged women, particularly white-collar office workers Beauty is more than that and their physical structure and the facing work, Living a double stress-related. Improve the psychological quality will help prevent disease, we should take things in stride optimistic approach to the environment.
Performance and causes of hyperthyroidism
Referred to as hyperthyroidism Hyperthyroidism is the result of excessive secretion of thyroid hormone, causing increased metabolic rate of a common endocrine disease. At present, the ratio of 1:6 for men and women hyperthyroidism. Patients usually manifested weight loss, easy to hunger, neck thick, rapid heartbeat, sweating, tremor and other symptoms, some people still associated with exophthalmos. A great impact on patients with hyperthyroidism, resulting in insomnia and irritability, affect the daily life and interpersonal relationships; female patients will appear menstrual disorders, menstrual less, is not easy to pregnancy, or even the pregnant will appear the possibility of stillbirth. Hyperthyroidism can also lead to serious cardiovascular disease, liver dysfunction, muscle weakness and so on. Hyperthyroidism caused by many reasons, the main factors include: heredity, some cases are familial aggregation phenomenon, parents, hyperthyroidism, children can easily incidence; iodine intake, such as iodine intake is too high; emotional suppression and long-term in the high pressure is a key factor in hyperthyroidism.
Little experience hyperthyroidism diet inequality
Now most patients tend to place more emphasis on intake of high-calorie food, ignore the intake of vegetables and fruits. Prevention and treatment of hyperthyroidism, not only to avoid excessive intake of one-time, but also appropriately increase meal times, regular meals, the meal with a sub-2 ~ 3 times, such as the increase in snacks between meals. In addition, the proposed multi-colored intake of a variety of fresh fruits and vegetables, such as carrots, celery, black fungus, lily, mulberry, Chinese wolfberry, Chinese yam, Gorgon fruit, jujube, watermelon, oranges, apples and so on.
Do not give himself too much pressure
To come to clinic patients are mostly energetic, always striving for perfection, the work of dedicated professional women, such as the foreign staff, teachers, accountants, etc., and be faced with a female high school entrance examination. They are more than 25 years old. This and their level of activity and stability of the endocrine not a relationship, when exposed to great work, life stress, mental and other incentives to stimulate the role of women than men more likely to have abnormal autoimmune regulator, triggering a high excess of thyroid hormone secretion metabolic syndrome. Got hyperthyroidism will make people become very sensitive, often to the end, these strong women can not get classes, home care is also not good, the pressure caused by the disease so that they completely lost the normal order of life. Aspects of the mental state may be due to over-excited cause sleeplessness, over-react to external stimuli, and even lead to personality changes. Strong woman experiencing these health crisis, we should look for physician examination, treatment as soon as possible, or easy to aging.
