What is thyroid hypodensity?

During the examination, if a low-density thyroid shadow appears, it may be due to an abnormal space-occupying echo, which may be a cyst, a cystadenoma, or a space-occupying lesion. We know that thyroid cyst is a common disease and has a great impact on the health of healthy patients. It can easily cause ischemic necrosis of tissues, compress the trachea and cause breathing difficulties, and even induce cancer. Therefore, in this case, further pathological examination should be carried out.

The harm caused by thyroid cyst disease: 1. Thyroid cysts can easily lead to ischemic necrosis of tissues, eventually forming necrotic cysts, and blood vessels lose tissue support and rupture. A more serious case is the appearance of serous cysts, the cyst walls of which are mostly fibrous connective tissue with fewer epithelial cells. 2. When the thyroid cyst grows to a certain size, it will compress the trachea, esophagus and recurrent laryngeal nerve, causing the trachea to bend or narrow, and finally symptoms of difficulty breathing, difficulty eating and hoarseness will appear. If you do not go to the hospital for treatment in time, it will become a necrotic cyst and lead to cancer. 3. After suffering from thyroid cyst, the patient will be in a very irritable mood, and will have symptoms such as chest tightness, shortness of breath, increased appetite, trembling hands, diarrhea, gradual weight loss, and poor sleep. 4. If patients with thyroid cysts are not treated for a long time, they will develop hypothyroidism, with symptoms such as fear of cold, loss of appetite, weight gain, slow growth and development, short stature, and intellectual disability. The tissues around the cysts will become necrotic, and the blood vessels will lose tissue support and rupture, leading to bleeding.

Causes of thyroid cysts: 1. Everyone knows that long-term iodine deficiency or excess in the body will cause thyroid diseases. For example, in the case of long-term iodine deficiency, the concentration of thyroxine in the blood is reduced, and through the neuro-humoral regulation pathway, the anterior pituitary gland secretes a large amount of thyrotropin, which causes the thyroid gland to enlarge. This enlargement is actually a compensatory enlargement of the thyroid gland, a phenomenon of insufficient thyroid function, and the cause of thyroid cysts.
