1. Follow the doctor’s orders for regular follow-up examinations. Follow-up time: 4 weeks after discharge for the first outpatient checkup, then once every 2-3 months, gradually transitioning to once every 6 months, then once every 1 year, and finally once every 2-3 years. 2. It is best to follow the date of the main surgeon’s visit for follow-up, he knows your condition best! The content of follow-up: thyroid function and thyroid ultrasound, CT or nuclear examination if necessary. After thyroid cancer surgery, you still need to review chest X-ray and bone scan etc. regularly as appropriate. 3. There is no significant effect on eating when reviewing neck ultrasound and thyroid function. Medication: Whether to take medication after surgery needs to be based on the patient’s specific postoperative conditions (such as thyroid function and clinical symptoms). Oral thyroid tablets can increase T3 and T4 levels in the blood and inhibit TSH secretion, thus playing a role in inhibiting the recurrence of thyroid nodules. Patients who have had more than one side of the thyroid gland removed need to take thyroxine replacement therapy after surgery, and the dose is adjusted according to the thyroid function after taking the medication. Oral administration of eugenol early in the morning at the time of review may have a slight effect on FT4 results, and it is recommended that it not be taken on the day of the review if possible. If the review of liver function, fasting blood glucose and lipids should be fasting. 4. Please bring your surgical history, surgical records, post-operative pathology, etc. for your doctor’s reference for the review! If you are not operated in our hospital, you should bring them with you to avoid misjudging your condition and causing adverse consequences. If the patient does not know the details of his or her condition, please bring along an informed family member. Previous examination data should be brought along for reference. You should know about oral medications and bring them with you if necessary. 5. Nodular goiter or adenoma should be reviewed regularly at the outpatient clinic after surgery because the residual thyroid tissue may continue to grow and recur. 6. After hyperthyroidism, T3, T4 and TSH should also be rechecked regularly at the outpatient clinic to pay attention to any recurrence or hypothyroidism. 7. Oral thyroxine (such as eugenol) must be taken after thyroid cancer surgery. For those who have hoarseness or choking cough after surgery, most of them are caused by compression and pulling of nerves due to tissue edema, which can be recovered after 3 to 6 months after surgery. 8. If no special instructions are given, moderate amount of iodized salt or seafood can be consumed.
