The thyroid isthmus does not grow back after thyroidectomy.
Patients who need to undergo isthmus thyroidectomy usually suffer from hyperthyroidism, thyroid tumors, etc. The isthmus of the thyroid will not grow back once removed, and hypothyroidism may also be induced after thyroidectomy. The symptoms of hypothyroidism need to be treated with levothyroxine sodium tablets under the guidance of a doctor to maintain thyroid hormone levels within a reasonable range.
After thyroidectomy, patients should rest more, maintain a balanced and comprehensive diet, and go to the hospital for regular checkups of thyroid ultrasound and thyroid function.
If you are not sure about the precautions to be taken after thyroid surgery, you can consult a professional doctor.
