5 month 15 is the twenty-fifth day for the prevention and treatment of iodine deficiency in China, the theme is.Amp, lsquo iodine.Amp, rsquo bright life, shared healthy life, and this week in May 25th, or the global scope Week of propaganda activities of thyroid health knowledge. What is the relationship between iodine intake and thyroid gland? Most of the salt on the market is iodized salt. Compared with the past, do we still have iodine deficiency? Is there a problem of excess iodine? The main source of iodine intake in
is water. Whether the iodine need to be supplementation is
except seafood, salt and grain, the main source of iodine intake is water, but in most areas of China, iodine deficiency is still in the vast majority of the country, and there are 14 cities and 100 counties in Shandong still belong to iodine deficiency state. Jiang Ling, deputy director of Department of Endocrinology, Qilu Hospital of Shandong University, said that the healthy population can generally be judged according to whether the area is iodine deficient or high iodine area. According to the latest "guide for Chinese residents' iodine supplement" published in 2018, most areas in China are iodine deficiency areas. In the 17 cities of Shandong, 14 cities, such as Ji'nan, Qingdao, Zibo, Zaozhuang, Dongying and Yantai, still belong to the iodine deficiency area. Only Shanghe County in Ji'nan is a high iodine area, and most of the other areas are almost all iodine deficiency, and the situation of iodine deficiency in the external environment is difficult to change. Therefore, it is necessary to eat iodized salt for a long time. Iodine in human body is mainly derived from various foods and drinking water. If food and drinking water are iodine deficiency, it will cause human iodine deficiency, not to eat seafood more than to make up iodine, such as Qingdao, Yantai and other places by the sea still belong to iodine deficiency.
in addition to hyperthyroidism and other special patients, ordinary people need to eat iodized salt. 5 grams of salt a day can ensure normal iodine intake. Ceng Qingdong, the chief physician of general surgery in Qilu Hospital, Shandong University, said that iodine is a necessary trace element in the human body. It is an essential raw material for the synthesis of thyroid hormones. It has an irreplaceable role in the growth, development of the brain, the regulation of metabolism and other organs. When iodine intake stopped, iodine stored in the body lasted for only 2-3 months. In addition to those with special diseases and those living in areas with high iodine content in water sources, it is not necessary to consume iodized salt.
thyroid cancer, thyroid nodule and iodized salt are not related to
thyroid nodules, thyroid cancer, is it caused by excessive iodized salt? Ceng Qingdong said there is no evidence that salt iodization is associated with high incidence of thyroid cancer, and according to the latest national thyroid forums this year, the increase in thyroid nodules can not be attributed to an increase in iodine intake, but the increase in iodine intake is a protective factor for thyroid nodules. .
hyperthyroidism and hypothyroidism all belong to autoimmune diseases, not caused by eating salt. Many people have misunderstood this. Ceng Qingdong said that the causes of hypothyroidism include autoimmune injury, thyroidectomy, radioactive iodine destruction, external exposure, iodine deficiency, or iodine excess. As for thyroid cancer, X ray injury is the most important pathogenic factor. So far, there is no definite evidence of excessive iodine intake and thyroid cancer. The increase of risk is related. The vast majority of thyroid diseases actually belong to the problem of individual constitution and immunity. Inadequate intake of iodine
can cause iodine deficiency disorders, such as endemic goiter (commonly known as large neck disease), endemic cretinism. What's the harm of that excess iodine?
common iodine excess is divided into water, food and drug. The excessive salt of the salted seaweed and the salted salted pickles of this kind of seaweed can lead to excess iodine. Long term antiarrhythmic amiodarone also has a problem of excessive iodine intake. Jiang Ling explained that our current standard of iodized salt is determined according to the situation of our province, and there is no need to worry about the excessive iodine consumption caused by iodized salt. Of course, hyperthyroidism should still be low iodine diet, so as not to supply excess raw materials to the synthesis of thyroid hormones. The main treatment for hypothyroidism is to supplement thyroid hormone, and excessive iodine supplement is also not beneficial.
urine iodine is not accurate, the most reliable
WHO of thyroid function is recommended for normal adult iodine median 100-199.amp; mug/L is iodine sufficient index, pregnancy women 150-249.amp; mug/L is iodine sufficient index. The median urine iodine of children in Ji'nan is 193.10.amp and mug/L, which is suitable for iodine nutrition. The median urine iodine level of pregnant women is 154.90.amp and mug/L, which should be paid attention to by some people.
How do you tell if your iodine content is over standard? Can go to the hospital to do urine iodine examination, but the present test paper detection variability is very large, and iodine content data is the median of the group, personal examination is not necessary. Jiang Ling introduced that the price of urine iodine examination in Qilu Hospital was 50 yuan, which was greatly influenced by recent diet, such as drinking kelp soup a night before inspection, and the index could be several times as high as several times.
compared with urine iodine examination, regular B-mode ultrasonography and thyroid function tests are more accurate and valuable. Jiang Ling, the thyroid gland B ultrasound examination is a morphological examination, can distinguish whether there is a tumor, and can determine the majority of benign and malignant tumors, and the need for blood test to examine the thyroid function examination is to check the operation of the thyroid gland, check the thyroid gland is running normal, as long as thyroid function. Normal, do not have to care about the iodine problem. In addition,
studies suggest that the current prevalence of thyroid cancer is due to thyroid screening, and is associated with the extensive use of high resolution B ultrasound for the overdiagnosis of occult or microcarcinoma.
check that thyroid nodules do not need panic, most of the nodules are benign, malignant only about 10%-15%, and as long as early detection and early resection, the recovery effect after the operation is very good. Ceng Qingdong said.
