What are the items to check for iodine deficiency? Is the thyroid cyst iodine-deficient or iodine-excessive?

We all know that iodine deficiency can cause goiter, which is a thyroid disease, but at the same time, excessive iodine intake can also cause thyroid disease. Nowadays, iodine is generally added to table salt, so it is generally not too iodine-deficient. If you want to know whether you are iodine-deficient, you can also use some tests to determine whether you are iodine-deficient.

What are the items to check for iodine deficiency?

Serum Point

Compared with urine iodine, serum iodine content is relatively stable, but currently only a few hospitals provide this testing service. This is because it requires a relatively high sensitivity of the equipment, and there is no evaluation standard in my country. If you want to know whether your blood iodine value is excessive, you can only refer to the values ​​of the World Health Organization and foreign countries.

Thyroid volume

It refers to the use of B-ultrasound to detect the size of the thyroid gland. It is generally believed that iodine deficiency and iodine excess can cause thyroid enlargement.

Urinary iodine

After metabolism, 90% of the iodine ingested by the human body is excreted through the kidneys. Therefore, by testing the iodine content in urine, the iodine nutritional status of the human body can be evaluated. However, urinary iodine can only reflect the situation in the past two or three days. Many factors such as diet, sweating, and water intake will have a great impact on urinary iodine. For example, if you eat a plate of cold kelp and drink a bowl of seaweed soup the day before, the urinary iodine may increase significantly and exceed the appropriate value. Therefore, everyone should pay attention to their diet a few days before testing urinary iodine.

Is thyroid cyst caused by iodine deficiency or excess?

Both excessive iodine intake and iodine deficiency can lead to thyroid diseases. Whether you have iodine deficiency should be diagnosed in the hospital.

There are many causes of thyroid cysts, including nodular goiter and thyroid adenoma. The occurrence of these lesions that can cause cystic changes is generally related to the daily iodine intake. At present, the iodine content of many table salts in China is high. Coupled with the fast pace of life and high pressure, the incidence of thyroid nodules has increased significantly.

If the thyroid cyst is not serious, surgery is generally not required. However, if the cyst is large and compresses the surrounding tissues and causes compression symptoms, you may choose to puncture and extract the cyst fluid or surgically remove it.

Symptoms of iodine deficiency

1. Adults

Iodine deficiency can cause goiter, commonly known as goiter. The principle is that due to the lack of iodine, the body's synthesis of thyroid hormone is reduced, which in turn causes the hypothalamus and pituitary gland to secrete more thyrotropin-releasing hormone (TRH) and thyroid-stimulating hormone (TSH), which act on the thyroid gland to increase the number of follicles and swell. The neck looks enlarged, and symptoms may include dry skin, irritability, etc.

2. Children

Iodine deficiency in childhood can cause a more serious disease, cretinism. From the physiological effects of iodine, it can be seen that iodine plays an important role in the growth and development of bones and the central nervous system. Deficiency will lead to developmental retardation. Compared with peers, they will be short in stature and their intelligence will be significantly lower than that of their peers.

3. Iodine deficiency in pregnant women

The fetus may be deformed and prone to miscarriage, and the newborn may suffer from diseases such as thyroid enlargement.
