In the immediate postoperative period after thyroid removal, care should be taken to limit neck movement to avoid poor healing of the incision or secondary bleeding after activity. After surgery, a full liquid diet should be followed to avoid excessive speech, which can also affect the healing of the postoperative wound. In addition, monitor thyroid function, especially in patients with subtotal thyroidectomy or malignant tumors who undergo glandular resection and lymph node dissection. After surgery, the thyroid gland is prone to hypothyroidism and even parathyroid damage, and thyroxine tablets and calcium supplements are needed if necessary. During the treatment period, it is also important to monitor the changes in blood count and biochemical indicators, and to pay attention to a full liquid diet, as well as to take appropriate nutritional supplements, including high-protein foods and high-calorie foods.
