There are no top ten contraindications after thyroid surgery. Contraindications after thyroid surgery are mainly related to postoperative wound care, postoperative dietary regulation, postoperative regular review, etc. Postoperative precautions are recommended to follow the doctor’s advice. Complications may occur after thyroid surgery, and the patient’s vital signs should be closely monitored after surgery. As the wound of thyroid surgery is on the neck, the patient should firstly take bed rest and reduce the activity of the neck so as to avoid bleeding from the wound; secondly, the patient should keep the respiratory tract open and observe whether there is bleeding from the wound as well as whether the drainage tube of the neck is blocked, so as to prevent the formation of hematoma locally, which will lead to asphyxiation due to compression of the trachea. Diet after thyroid surgery is also very important, need to pay attention to balanced nutrition, quit smoking and alcohol. It is also necessary to decide the intake of iodine-containing food according to the function of the thyroid gland. If the function of the thyroid gland is hypothyroid, you can consume iodine-containing food appropriately, such as kelp and seaweed. Thyroid surgery does not provide a permanent solution. Thyroid tumors have a certain degree of recurrence, and post-surgery patients still need to follow the doctor’s instructions for regular review to find out if there is any possibility of recurrence or metastasis of the tumor.
