Thyroid cyst is a fluid sac in the thyroid gland. Generally, there is no pain symptom or the pain is not obvious. If the cyst is very large, some compression symptoms will appear, such as difficulty swallowing. In many cases, this is an endemic disease and is closely related to iodine deficiency.

1. Introduction to thyroid cyst

A thyroid cyst refers to a sac-like mass containing fluid found in the thyroid gland. Thyroid cysts usually have no symptoms unless the cyst is very large or there is bleeding in the cyst, which may cause some compression symptoms such as pain, difficulty swallowing, difficulty breathing, hoarseness, etc. Generally speaking, thyroid cysts rarely contain malignant cells and usually only require observation to see if there is a tendency for them to grow larger.

2. Causes

Thyroid cyst is an endemic disease mainly caused by iodine deficiency, which causes thyroid hyperplasia, thyroid cysts and degenerative lesions. Patients with thyroid cysts do not feel any discomfort and often discover the tumor in the front of the neck accidentally. However, to treat thyroid cysts, it is necessary to understand some of the causes of the disease, which is very helpful for the treatment of the disease.

Thyroid cysts are sometimes caused by excessive liver fire in the body, or emotional injury, which causes liver qi to become depressed and thus trigger thyroid disease. Some are related to the menstrual period of some women, pregnant women, and women who have given birth. It is also related to some physiological dysfunctions and physical factors. Women are more susceptible to it. Thyroid cysts caused by this cause are mostly solid at first, but will turn from solid to virtual after a long time, or a mixture of solid and virtual.

Thyroid cysts are sometimes also related to iodine deficiency in the body. As the body absorbs less iodine, the thyroid hormone concentration in the patient's blood will decrease. Through fluid regulation, the anterior pituitary gland will secrete more thyrotropin, thus forming a thyroid cyst. This is a phenomenon of thyroid hypofunction.

Symptoms

The symptoms of thyroid cysts mainly include palpitations, chest tightness, heat intolerance, sweating, hand tremors, insomnia, increased appetite, weight loss, fatigue, diarrhea, goiter and exophthalmos. The onset is relatively acute. The thyroid gland is enlarged and hard on one side or both sides, accompanied by local pain, which often radiates to behind the ears and the back of the head. The whole body may have chills and fever. It is more common in middle-aged women. The thyroid gland is mostly diffusely enlarged; some may appear as nodules, which are painless and have no systemic symptoms. Some patients have symptoms of hyperthyroidism, and those with long-term illness may have some symptoms of reduced thyroid function, such as decreased appetite, weakness, mild edema, etc.
