Radiofrequency ablation is a method of destroying tumors with heat caused by the friction of ions in the tissue under the influence of high-frequency alternating current. The heat caused by friction dries the surrounding tissue leading to dehydration of the cells and coagulation of the tumor, thereby reducing the size of the tumor.

The majority of thyroid nodules are dormant and usually appear only when the tumor increases in size, causing local compression, leading to difficulty swallowing, difficulty swallowing, feeling of choking or hoarseness, changes in voice.

Benign thyroid tumor is a common disease in women, patients with lumps in the neck cause discomfort or even difficulty breathing or swallowing. Treatment methods vary depending on the nature and extent of the tumor. There are 4 main treatment methods: monitoring, antithyroid drugs, surgery and aspiration.

TSH stands for thyroid stimulating hormone, which is produced by the pituitary gland in your brain. This gland tells your thyroid gland to make and release thyroid hormones into your blood.

Thyroid function tests including TSH, total T4, FT3, TSI and other components play an important role in the diagnosis and treatment of thyroid diseases.

The pituitary gland has different types of glandular cells, each type of glandular cell secretes a corresponding type of hormone and simultaneously affects other organs or endocrine glands of the body. The anterior pituitary gland produces hormones that have the effect of regulating the body's activities on a very wide range. The anterior pituitary gland secretes at least seven different types of hormones while the posterior pituitary gland produces only two types of hormones.

Growth hormone plays a very important role in the human body, at a moderate level it can help develop bone length, stimulate other organs in the body. Excess growth hormone leads to many consequences, typically pituitary diseases, greatly affecting the patient's health.

In the elderly, endocrine changes lead to endocrine dysfunction related to tissue responsiveness as well as decreased hormone secretion from peripheral glands.

About 3-4% of pregnant women have thyroid dysfunction. Thyroid dysfunction in pregnant women can cause dangerous complications for both mother and baby if not treated promptly.

The endocrine system is made up of many different glands. The hypothalamus, pituitary gland, and pineal gland are in the brain. The thyroid and parathyroid glands are in the neck. The thymus gland is between the lungs, the adrenal glands are above the kidneys, and the pancreas is behind the stomach. The ovaries (in women) or testicles (in men) are in the pelvic area.

Sodium is an important electrolyte that plays a role in cell membrane function. When blood sodium is low, electrical activity is easily affected, causing serious consequences. However, if it is due to abnormal ADH secretion syndrome, the core treatment of hyponatremia is simply to limit fluid intake instead of hypertonic sodium replacement.
