Thyroid cancer is gradually increasing, but once people are deficient in iodine, what harm will it b

Iodine is one of the essential nutrients for the body, and is an important raw and auxiliary material for the formation of thyroid hormones, which is very important for human life activities. If iodine deficiency is very likely to cause these health and safety risks:

Iodine deficiency can lead to reduced thyroid function and mental and physical weakness.

More severe iodine deficiency will cause "cretinism", which is reflected in significant mental retardation and short stature, in addition to the possibility of ear deafness, dumbness, etc., which is directly related to a person's life.

Iodine deficiency in expectant mothers can harm the growth and development of the fetal central system, and even cause malformations, miscarriage or death. It is precisely because of the importance of iodine that in order to better solve the lack of iodine intake of the common people, China has begun to implement salt iodization for all personnel 28 years ago, and implement salt iodization for different areas and groups of people, and carry out scientific and standardized iodine supplementation.

However, due to the gradual variety of foods, the incidence of thyroid nodules and thyroid cancer has gradually increased, and the suspicion of iodine has gradually increased. Many people will be suspicious, is it necessary for everyone to continue to eat iodine?

Usually, thyroid nodules and thyroid cancer increase, not because of too much iodine, but because China's diagnosis and treatment technology work capacity and diagnosis and treatment service level have been significantly enhanced. There are more people of all ages who have physical examinations, and more and more people have a better grasp of their own body, so that nodules and thyroid cancer that were not detected can be detected immediately.

For benign thyroid nodules, there is actually no need to worry very much, and it will not cause great damage to the health of the body and daily life. How can we prevent thyroid cancer in our daily life? Thyroid cancer is characterized by low malignancy and a good recovery period.

In recent years, the incidence of thyroid cancer has been on the rise. "Early detection, early diagnosis, and early diagnosis" is an important specific method for treating thyroid cancer. In daily life, it is necessary to develop a good subconscious, sleep periodicity, reasonable nutrition, weight control, and moderate exercise.

Avoid exposure to radioactive materials in the neck and contact with dust of radioactive elements. Maintain a happy mood, learn to regulate negative emotions, release stress, avoid overwork, take medicine under the guidance of a doctor, avoid abuse of skin care products and health products, and prevent excessive estrogen secretion. People who have been suffering from benign thyroid symptoms for a long time or have a family history of thyroid cancer should undergo thyroid ultrasound selection on time to detect abnormalities immediately.

If people are deficient in iodine, it will lead to low vision, memory loss, and if pregnant women are deficient in iodine, it may lead to stillbirth, miscarriage and premature birth, so for normal and healthy people, iodine deficiency can not be done in life, which will affect people's normal work and life.

I think the harm to the body is still very serious, once the lack of this trace element, may lead to hair loss, lack of energy, fatigue, body soreness, or the occurrence of some diseases, the harm to the body is still very serious.

Iodine deficiency is followed by iodine deficiency, which can manifest as goiter, endemic cretinism, miscarriage, premature birth, stillbirth, and congenital malformations in pregnant women. In addition to the above-mentioned iodine deficiency diseases, iodine deficiency can also lead to hypothyroidism, hyperthyroidism, and thyroid follicular carcinoma.

Patients with endemic goiter will have thickened neck due to goiter, patients with endemic cretinism will have intellectual disability, short stature, strabismus, deafness, abnormal gait, paralysis, etc., and when hypothyroidism occurs, patients will become fatigued, cold intolerance, edema, lack of energy, poor appetite, weight gain, drowsiness, constipation, menstrual disorders, etc.

When hyperthyroidism occurs, there will be manifestations such as increased appetite, weight loss, palpitation, and hand tremors.

Hello, according to your description, you said that iodine deficiency can cause goiter, mainly due to the fact that iodine is an important raw material for the synthesis of thyroid hormones, and long-term iodine deficiency in the diet reduces thyroid hormone synthesis. The level of thyroid hormone in the blood decreases, and the negative feedback effect on the adenohypophysis is weakened, resulting in an increase in the secretion of thyroid-stimulating hormone in the adenohypophysis. Thyroid-stimulating hormone promotes thyroid cell proliferation, which can lead to thyroid enlargement.

If it is due to an iodine deficiency of the thyroid gland. Iodine supplementation is required in a timely manner**. Symptoms of goiter can be relieved by iodine supplementation.

Is it generally due to iodine deficiency?

First, the relative lack of iodine. When the environment is deficient in iodine and the concentration of inorganic iodine in the blood decreases, the thyroid tissue proliferates, and its iodine uptake function is enhanced, and the thyroid gland tries to take enough iodine from the blood in a state of low iodine to ensure the synthesis of sufficient thyroid hormones to supply the physiological needs of the body's tissues.

Second, due to long-term intake of too much iodine, there are too many inorganic iodine ions in the thyroid tissue, which hinders the organic process of iodine, resulting in a decrease in thyroxine synthesis, and high iodine may also inhibit the release of thyroxine, making the blood thyroxine more deficient, thus increasing the secretion of thyroid-stimulating hormone and causing goiter.

The main common thyroid diseases are hyperthyroidism, hypothyroidism, hypothyroidism, thyroid tumors, thyroiditis, thyroid cysts, and complications of hyperthyroidism.

The enlarged thyroid gland caused by the defect is also known as the Great Neck Disease. Iodine deficiency mainly leads to insufficient thyroxine synthesis, resulting in compensatory thyroid hyperplasia (compensatory hyperplasia is to synthesize thyroxine more). So the thyroid tissue will become larger, that is, the thyroid gland will be enlarged.

Both statements are true, but from different angles. Iodine deficiency leads to low thyroid hormone secretion, which increases thyroid-stimulating hormone secretion, which increases thyroid absorption of more iodine. This causes endemic goiter. Take care to distinguish between thyroid hormone and thyroid-stimulating hormone.

Iodine deficiency leads to decreased thyroid hormone synthesis and therefore increased thyrotropin-releasing hormone and thyroid-stimulating hormone secretion, resulting in endemic goiter.

Thyroid cancer is a relatively rare type of cancer, which is highly prevalent in young adults, and the number of thyroid cancer in the world has been increasing, especially in China in recent decades, the number of thyroid cancer patients has increased many times. With the increase in the number of thyroid patients in China, there has been a rumor that it is related to the excessive iodine intake of people nowadays, is this statement correct? If you want to analyze the impact of iodine excess on the body, you only need to analyze our neighbor "Japan", which often eats seafood such as kelp and seaweed, so the per capita iodine intake of Japanese people has always been the first in the world, and it has far exceeded the average daily iodine intake recommended by the World Health Organization.

But what is the result? The Japanese are one of the countries with the longest average life expectancy in the world, especially the incidence of thyroid cancer, compared with other countries with low or normal iodine intake, has not increased significantly, which indirectly shows that excessive iodine intake has a limited impact on human health, at least it is not the cause of thyroid cancer, so the diet is different from too much entangled iodine content. So what are the factors that really have to do with the incidence of thyroid cancer?

There are only two things that have really been confirmed: 1. Radiation-related This is the most closely related factor known to thyroid cancer, and the incidence of thyroid cancer is significantly higher than that in other parts of the world, Hiroshima, Nagasaki and Chernobyl, which are widely known to have been contaminated by nuclear weapons. In addition, many cancer patients have an increased risk of thyroid cancer after receiving high-dose radioactive radiotherapy**, including X-rays, CT and other slightly radioactive physical examinations.

2. Genetic correlation According to research, more than 50% of this subtype is caused by RET gene mutations, and 15% of them are hereditary, so the hereditary factors of thyroid cancer should not be underestimated. For thyroid cancer, first of all, of course, it is necessary to prevent it, especially children, and it must be kept away from the radiation environment, and secondly, there is no need to panic too much, thyroid cancer is the cancer with the highest survival rate and ** rate among all cancer types, and there is no one, if it is detected early, the ** rate is basically 100%. Therefore, pay attention to prevention, even if you suffer from thyroid cancer, don't think that it is a terminal disease, as long as you are positive, there is still a lot of hope.

The human thyroid gland secretes thyroid hormones, and iodine is an important raw material for the production of thyroid hormones, and the elderly need about 100 to 150 micrograms of iodine per day, mainly in diet.

Due to the vigorous metabolism of the human body during puberty, the human body needs a high amount of thyroid hormone, so the amount of iodine required is also relatively increased.

In the same way, if the elderly eat less, eat partially, or live in iodine-deficient areas in plateaus and mountainous areas, the iodine content in drinking water, food and salt is low, iodine deficiency will also occur in the body, resulting in goiter.

In mild cases, the use of iodine-containing drugs or eating more iodine-containing foods, such as kelp, seaweed, etc., can shrink the enlarged thyroid gland; In severe cases, surgery is only possible to remove the enlarged thyroid gland.

Especially now, people eat too much salt and iodine, and if this goes on for a long time, it will cause a kind of thyroid lesion, and once the thyroid gland is damaged, then cancer will slowly form, so you should pay attention to your diet.

It is also possible that there is a risk of iodine excess, and iodine is also fully available in coastal areas through seafood, such as kelp and fish.

It's not that iodized salt is to blame, it's mainly due to bad eating habits and irregular work and rest times, and it also has a lot to do with a person's mood, so we also have to maintain a good attitude.

There are people in life who have thyroid disease and don't know what to do? It is not clear whether iodine supplementation should be done or if practical iodine should be reduced. I feel like before we ask this question, we need to figure out what exactly the thyroid is, which is located in the middle of the front of our neck, and it secretes two thingsOne of them is thyroid hormones, which are essential for the growth of the human body.

Thyroid hormones are what we live byWithout it, we probably wouldn't be able to survive at all. Thyroid hormone is mainly produced by the thyroid gland, and iodine is necessary to produce thyroid hormone, and if our body lacks iodine, it may cause our thyroid gland to become swollen or nodular. Therefore, we can't say exactly whether we should avoid iodine or supplement iodine?

It only depends on the physical condition of each person.

First of all, for those with hyperthyroidism, they should avoid iodine or have little iodine, because the disease is caused by an excess of thyroid hormones. There is also the condition of hypothyroidism, which is caused by a lack of iodine, therefore, iodine should be supplemented, but for the amount that needs to be supplemented, you should go to the hospital to consult a doctor, and you can't check it on the Internet privately, or supplement it at will, otherwise, it will affect our body.

In addition, patients with hyperthyroidism and thyroid cancer should stop taking drugs and foods containing iodine during intranuclide irradiation**。Generally speaking, the contraindication time is four weeks, but the specific condition still depends on the doctor. The doctor knows the patient's condition best, so whether the thyroid patient should take iodine supplementation or avoid iodine also needs to listen to the doctor.

Although our thyroid gland itself needs iodine, it is not enough to have more or less of this thing.

When I was studying, there was a text that said that if you eat salt that is not iodized, you will get a big neck disease. Therefore, I think it should be iodine supplementation, but now salt is iodized, and it can be supplemented when eating vegetables.

It should be iodine supplementation, because the salt we eat contains iodine.

I feel that this kind of situation should be supplemented with iodized salt, after all, this is good for the thyroid gland.

To prevent thyroid cancer, iodine supplementation is of course.

I think it should be iodine supplementation, and it is best to take it in moderation, otherwise it is easy to get sick.

Just supplement the normal needs of the human body, too much or too little iodine is not good.

Because iodine is needed to produce thyroid hormones, iodine supplementation is required.

Don't add to this, go to the hospital to inquire before deciding.
