What causes thyroid nodules in men?

Thyroid nodules are a very common disease, and sometimes they are regional in nature. They can have many adverse effects on human health. In fact, they can be treated with some drugs in a timely manner after they are discovered. Before treatment, it is best to identify the specific causes. Let's take a look at some of the more common causes of thyroid nodules in men.

1. Iodine deficiency:

It is one of the main causes of endemic goiter. The iodine content in soil, water and food in epidemic areas is inversely proportional to the incidence of goiter. The fact that iodized salt can prevent goiter proves that iodine deficiency is an important cause of goiter. In addition, the body's increased need for thyroid hormone can cause relative iodine deficiency, such as growth and development period, pregnancy, breastfeeding, cold, infection, trauma and mental stimulation, which can aggravate or induce goiter.

2. High iodine:

It is rare and may be local or sporadic. Its pathogenesis is that excessive iodine intake leads to excessive occupancy of TPO functional genes, thereby affecting tyrosine iodination, hindering the organic process of iodine, and causing compensatory thyroid enlargement.

3. Hormone synthesis disorder:

The cause of familial thyroiditis is a genetic enzyme defect that causes hormone synthesis disorders, such as a lack of peroxidase or deiodinase, which affects the synthesis of thyroid hormone, or a lack of hydrolase, which makes it difficult for thyroid hormone to separate from thyroglobulin and release into the blood, all of which can lead to thyroiditis. This congenital defect is a recessive genetic trait.

4. Goitrogenic substances:

Radish foods contain thiourea-type goitrogens, and soybeans and cabbage also contain certain substances that can block the synthesis of thyroid hormones, causing thyroid enlargement. The content of minerals such as calcium, magnesium, and zinc in soil and drinking water is also related to the occurrence of goiter. In addition to iodine, some endemic areas also lack the above elements. In some areas, the incidence of goiter is proportional to the hardness of drinking water. Drugs such as potassium thiocyanate, potassium perchlorate, para-aminosalicylic acid, thiouracil, sulfonamides, phenylbutazone, colchicine, etc. can hinder the synthesis and release of thyroid hormones, thereby causing goiter.

For patients with thyroid nodules, it is best to choose a reasonable diet according to their physical condition and the cause of the disease, and try to avoid the possibility of more serious diseases caused by iodine deficiency or high iodine. You can also do some appropriate physical exercise to enhance the body's resistance to diseases.
