Usually after total thyroidectomy, the decision to take calcium supplements for the rest of your life depends on your condition. If the hypocalcemia is temporary, then calcium supplementation can be stopped as directed by the doctor when the condition returns to normal. If the hypocalcemia does not return, long-term calcium supplementation may be required. Some patients may have complications such as hypocalcemia after total thyroidectomy, so they need to take calcium supplements as prescribed by the doctor. However, it is worth noting that patients do not necessarily need to take calcium supplements for the rest of their lives after surgery, and they can stop taking calcium supplements as prescribed by their doctors when they recover from surgery. If it is clear that there is no deficiency of calcium after surgery, then there is no need to take additional calcium supplements, and it is sufficient to pay attention to monitoring the condition of the patient. Patients should strengthen the surgical wound care, avoid foreign body friction and stimulation, and prevent infection. It is recommended that patients should follow the doctor’s instructions for medication after total thyroidectomy, and should not use medication indiscriminately on their own. Attention should be paid to regular medical checkups in order to monitor the changes of the condition.
