In recent years, the overall detection rate of thyroid abnormalities is as high as 22%, which means that 2 out of every 10 people are affected. Thyroid nodules, hyperthyroidism, hypothyroidism, and Hashimoto's thyroiditis have become common thyroid problems that plague the nation, and even the incidence of thyroid cancer is increasing dramatically.

The thyroid gland is a small gland, but it is very important for the functioning of the body. Its secretion of thyroid hormones not only regulates the body's metabolism and promotes growth and development, but also affects the heart function, digestive system, and nervous system. It can be said that thyroxine acts on almost all tissues of the body and is vital to health.

So what exactly causes thyroid abnormalities?

The 5 main "culprits" of thyroid disorders

Although the incidence of thyroid disease is increasing, the specific pathogenesis is not well understood and may be related to the following factors.

1 Nighttime light may increase the risk of cancer

Recently, a study found that the highest exposure level increased the risk of thyroid cancer by 55% compared to the lowest exposure level of nighttime lights.

Among them, nighttime lights had a higher impact on women than men, with an 81% increase in risk for women and a 29% increase in risk for men.

Night lighting

The main reason for this is that nighttime light suppresses the secretion of melatonin at night, which tends to cause circadian rhythm disturbance, which may also be a risk factor for cancer.

In addition, the light emitted from indoor computers, TVs and cell phones can also interfere with the circadian rhythm of the human body to a certain extent. Therefore, it is better to sleep with lights off and play fewer electronic products before going to bed.

2 Iodine, too much too little is not good

Iodine is an important raw material essential for the synthesis of thyroid hormones. But too little iodine in the body will lead to too little secretion of thyroxine and cause goiter, while too much iodine may cause hyperthyroidism, thyroiditis, etc.

The amount of iodine content will have a direct impact on thyroid function. About 150 micrograms of iodine per day is a normal intake for an adult, while pregnant and lactating women can consume about 250 micrograms of iodine. This can be supplemented by appropriate consumption of iodized salt and seafood such as kelp and nori with high iodine content.

However, for residents of high iodine areas, such as some areas in Bohai Bay, who often consume seafood, it is best to choose non-iodized salt and strictly control the intake of foods with high iodine content.

3 Low selenium level and relatively higher cancer risk

Selenium is the second essential trace element for the thyroid gland. Selenium deficiency, on the one hand, will lead to a disorder of the human immune system and increase the risk of thyroiditis and hyperthyroidism; on the other hand, it will reduce the body's utilization of thyroid hormones and increase the crisis of goiter.

Some studies have even shown that the lower the selenium level in the body, the higher the risk of getting thyroid cancer. For patients with thyroid cancer, the lower the selenium level, the higher the malignancy of the tumor and the worse the recovery in the future.

Some clinical trials have also found that proper selenium supplementation can synergize with iodine to maintain the balance of thyroid hormones. Daily, you can appropriately consume more animal offal, goose eggs, mulberry, seafood, and other foods containing selenium. Especially in China, 72% of the region is in the low selenium zone, you can also take selenium supplements when necessary.

4 poor health, often cold, thyroiditis prone

The occurrence of colds is inherently related to the body's immune system decline. And like a viral cold will make the mucous membrane of the upper respiratory tract infected, and the inflammatory response, if the inflammatory response is strong, it may involve the thyroid gland.

Subacute thyroiditis usually occurs easily 1-2 weeks after the flu or cold.

When fever, neck pain, as well as excessive sweating, panic attacks, mood changes, and significant tenderness in the thyroid area occur after a cold, the possibility of subacute thyroiditis should be suspected. It is recommended to go to the hospital for a timely examination instead of continuing to take medication on your own.

5 Intestinal flora imbalance, osmotic changes, impaired thyroid function

When the intestinal flora is dysregulated, it will affect the absorption of nutrients, the absorption of minerals such as iodine and selenium will be reduced, and the synthesis of thyroxine will be reduced.

In addition, some studies have found that gut microbes can recognize many endocrine hormones, including epinephrine, norepinephrine, sex hormones, and thyroxine, and even alter their metabolism.

And when intestinal permeability is altered or even leaky gut occurs, the gut cannot function well as a barrier, and some allergic antigens, bacteria, molds & toxins can enter the circulatory system, thus affecting thyroid function.

Overall, a balanced intestinal micro-ecosystem is good for thyroid health. Daily consumption of foods rich in dietary fiber and fermented foods can promote the growth of probiotics and protect intestinal health.

Protect the thyroid gland, two details can not be missing

To avoid thyroid disease, the above 5 dangerous "factors" should be avoided as much as possible, in addition to the following small details.

1 Balanced diet and appropriate nutritional intervention

1) Adequate amount of amino acids, which are the raw material for thyroid synthesis

Tyrosine, an amino acid, is also a raw material for the synthesis of thyroxine. When the level of tyrosine is too low, it may lead to the decline of thyroid function and hypothyroidism.

Foods rich in tyrosine, such as cheese, figs, sweet potatoes, celery, pineapple, bananas, etc., can be consumed appropriately daily.

Balanced diet

②Balanced minerals, a booster for thyroid gland operation

Although the national diet is becoming more and more selective, there is still a general lack of minerals, which is one of the important factors for the high incidence of thyroid disease. And in addition to the aforementioned selenium and iodine, there are the following.

* Zinc: It's responsible for triggering the hypothalamus to activate the production of thyroxine. Food sources of zinc include animal liver, pork, chicken, spinach, seafood, etc.

*Iron: Iron deficiency hinders the production of thyroid hormones and reduces the activity of thyroid peroxidase. Iron-rich foods include pig liver, duck blood, kelp, nori, fungus, etc.

③Adequate vitamins, which are the ignition for the thyroid gland to start

* Vitamin D: Vitamin D deficiency increases the risk of autoimmune thyroid disease. Statistics show that over 90% of people with Hashimoto's thyroiditis have vitamin D deficiency in their bodies.

*Vitamin E: An animal study showed that vitamin E protects animals from oxidative stress and thyroid cell damage.

*Vitamin B12: It helps to break down iodine, which increases the production of thyroid hormones. More studies have pointed out that vitamin B12 deficiency has a fairly high correlation with hypothyroidism.

*Vitamin A: The conversion of thyroid hormone T4 into usable free thyroxine T3 requires the involvement of vitamin A.

2 Self-examination + regular physical examination for early detection of abnormalities

Some of the early symptoms of thyroid disease are not very obvious, but they can cause great damage to the organism, so it is important to pay attention to self-examination daily to detect problems as early as possible~

① Self-examination of hyperthyroidism

Hold your hands forward and flat, palms facing down, five fingers apart and eyes closed. Place a white paper on the back of your hand and determine if your hands are shaking by the shaking of the paper.

Some hands do not tremble, but there will be a trembling of the tongue. If any of these problems occur, it is recommended to go to the hospital for a thyroid function test, and a blood draw will diagnose it.

② Self-examination of enlarged thyroid gland and nodules

Do a swallowing motion in front of a mirror and observe if there is a lump under the laryngeal node moving up and down following the swallowing motion, or place your hand under the throat in front of the neck to see if there is a mass.

Not only self-examination but also regular medical check-ups are very necessary.


*Annual thyroid ultrasound, preferably from the age of 35.

*For pregnant women, thyroid function tests are recommended.

*Before preparing for pregnancy, it is recommended that women be screened for thyroid-stimulating hormones and other related indicators.
