The thyroid gland is the largest endocrine organ in the body, and if it becomes diseased, it can have a significant impact on all aspects of the body, including the circulatory system, digestive system, and nervous system. Therefore, thyroid disease is relatively untreatable. Of course, not all thyroid diseases are untreatable, but compared to other diseases thyroid diseases have a longer course and require longer medication. Thyroid disorders include hyperthyroidism, hypothyroidism, Hashimoto’s thyroiditis, thyroid cancer, and many others. The treatment of different thyroid disorders varies, but the general principle of treatment is to control symptoms and reduce complications. For hyperthyroidism, treatment can be done by medication, surgery, iodine 131, etc. After this series of treatment, a more satisfactory result can be achieved. The treatment of hypothyroidism is mainly based on medication, such as Eugenol and Tirez, but the treatment of hypothyroidism is very long and some patients need to take medication for life. Hashimoto’s thyroiditis is also treated mainly with medication and surgery, while for thyroid cancer it can be treated conservatively or surgically. Patients suffering from thyroid disease should not be too negative and pessimistic. Although thyroid disease is not a very treatable disease, it actually does not have a great impact on the quality of life as long as the medication is used consistently.
