thyroid is the endocrine gland located in the neck. It maintains the balance of nutrients such as calcium, protein , and can also regulate the body's sensitivity to other hormones, which is of great significance to human health. The thyroid carries so many functions. Under high-intensity work, diseases are inevitable. For example, thyroid nodules is one of the most common ones.
thyroid nodules are lumps that occur in the thyroid gland. Their shape can be single or multiple, among which single-nodules may be more malignant. However, there is no need to worry too much. In clinical practice, about 90% of nodules are benign. But active treatment is still needed. The following symptoms of indicate that the thyroid nodules have come to you:
1) Palpitations , Chest tightness , fever, sweating, hand shaking, insomnia, loss of appetite, hyperactivity, loss of appetite, fatigue, diarrhea. The acute onset symptoms and signs of thyroid nodules, such as goiter on one or both, accompanied by local pain, and often behind the ear and behind the top of the radiation, the whole body will experience chills and fever.
2) The neck is thicker and has a soft texture. Generally, when the swelling is obvious, the front lump can extend forward or backward to compress it, causing dyspnea, or dysphagia .
3) There is neck lymph node metastasis, which may cause compression symptoms, such as poor breathing, swallowing, hoarseness and Horner signs, such as pupil shrinkage, ptosis, intraocular dipple, and no sweat on the ipsilateral face.
4) There are pimples in the thyroid gland, which grows slowly, generally single-shot, has a complete envelope, has clear boundaries with the surrounding normal tissues, no pain or tenderness, the nodules have medium hard texture, smooth surface, and no stickiness around and can be moved up and down swallowed.
cause of thyroid nodules:
Some minor diseases are always caused when you are not paying attention in life. As a serious minor disease, thyroid nodules should be taken seriously. In daily life, what exactly is the cause of thyroid nodules? Let’s learn about it below.
1) Iodine deficiency: is one of the main causes of endemic goiter. The iodine content of soil, water and food in endemic areas is inversely proportional to the incidence of goiter. The fact that iodine salt prevents goiter can prove that iodine deficiency is an important cause of goiter.
2) Dethyroid substance: radish contains thiourea caused by goiter substance. Soybeans and cabbage also have some substances that can prevent the synthesis of thyroid hormone , causing goiter. The content of minerals such as calcium, magnesium, zinc in soil and drinking water is also related to the occurrence of goiter.
3) Hormone synthesis disorder: The cause of familial goiter is hereditary enzyme defect, which leads to hormone synthesis disorders, such as lack of peroxidase . This congenital defect belongs to recessive inheritance .
4) Gene mutations: These abnormalities include exon of the thyroglobulin gene.
