Removal of the thyroid gland can be an effective treatment for thyroid disorders, especially for those who cannot be treated conservatively or for whom conservative treatment is ineffective, such as those with moderate or severe hyperthyroidism, huge thyroid, nodular goiter with hyperthyroidism, retrosternal goiter with hyperthyroidism, etc. In particular, thyroid tumors can be prevented from causing more harm to the body by the primary disease. The disadvantage of removing the thyroid gland is that the thyroxine secretes the thyroxine that the body needs, and if the thyroid gland is removed, the patient will need to take medication to replace the thyroxine for life. If the parathyroid glands are removed at the same time as the thyroid gland, the patient may suffer from calcium deficiency and will have to be treated with calcium supplements after the operation. If conservative treatment is possible, try to keep the thyroid gland.
