It is not necessary to take medication for life after thyroid adenoma surgery. This is because thyroid adenoma surgery depends on how much of the thyroid gland is preserved during surgery to decide whether to take it for life after surgery. If a particularly large number of thyroid glands are cut, you will need to take them for a long time, because a low functioning thyroid gland can also cause many symptoms, such as low thyroid function and slow metabolism, which can affect the heart and cause arrhythmia, as well as fear of cold, irritability, apathy and depression. Removal of thyroid adenoma is different from removal of thyroid cancer, which requires taking thyroxine tablets for life. This is because thyroxine tablets have the function of preventing the recurrence of thyroid cancer in addition to adjusting thyroid hormones. However, since thyroid adenoma is benign, the extent of removal will be less, so whether or not to take thyroxine tablets or how long to take them depends on the extent of thyroid gland removed during surgery.
