The thyroid gland is an endocrine gland in the human body. The treatment of thyroid gland diseases, including hyperthyroidism which occurs in the thyroid gland, is more common. There are three common treatments, namely surgery, medication and iodine-131 treatment, as explained below: a. Surgery, removing some or the entire thyroid gland, after three days of treatment patients will find that the disease has all disappeared, but after removing the thyroid gland, it will However, the removal of the thyroid gland can lead to a decrease in immunity and impairment of body functions. The use of anti-thyroid hormone medication, which inhibits the synthesis of thyroid hormones by inhibiting the organic iodine in the thyroid gland, can lead to improvement of the disease during the medication period, but once the medication is stopped, it will trigger the onset of the disease. Long-term use of the drug can also lead to skin lesions and a decrease in white blood cells and fever, as well as drug allergies such as sore throat and abnormal liver function. Thyroid-related diseases such as hypothyroidism and subthyroiditis require a series of treatments such as eugenol replacement therapy and glucocorticoids to suppress the immune-destructive reactions that occur in the thyroid gland. In addition to surgery, there are also radiotherapy treatments for thyroid cancer. III. Iodine-131 treatment, which destroys part of the thyroid tissue through the radioactive element iodine 131, so that the synthesis of thyroid hormones is reduced to achieve relief and control of hyperthyroidism, is a relatively safe and fast-acting treatment method, but it is found clinically that it is easy to induce hypothyroidism once hypothyroidism can be treated with eugenol replacement therapy.
