The removal of the thyroid gland does not usually have a direct impact on life expectancy if it is treated by a medical professional. There are two types of thyroidectomy: thyroid nodules or hyperthyroidism, which do not require any intervention and do not affect life expectancy after surgical removal of the thyroid gland or thyroid nodules. If abnormal thyroid function exists after surgery, stable health can also be achieved after taking the appropriate medication, which also does not affect life expectancy. Another situation is the surgical removal of thyroid cancer. However, thyroid cancer is inert compared with other cancers, and the majority of the pathologic types are better. With surgical removal and subsequent radioiodine therapy and thyroid suppression therapy, the majority of the patients have good long-term survival, and the impact on life expectancy is usually small. Patients requiring thyroidectomy are recommended to be treated in a regular hospital.
