After thyroid cancer surgery, it is necessary to regulate the physical condition and carry out standardized care under the guidance of clinicians, which mainly includes daily care, diet control, regular medication and regular review. 1. Daily care: just after the operation, avoid too strenuous exercise to prevent wound dehiscence; pay attention to relaxing mood and adjusting physical condition. 2. Dietary control: Try to eat mainly fluids in the early stage, and then pay attention to add diet slowly and avoid foods with too much iodine, such as seaweed. 3. Medication control: after the operation, you need to apply levothyroxine sodium tablets regularly to maintain thyroid function as much as possible. 4. Regular review: In the early stage, it is necessary to pay attention to regular review of the condition of the operation area (ultrasonography), CT of lungs and thyroid function (blood test), mainly for the fear of recurrence and metastasis, and standardized regulation of thyroid function. If there is obvious hoarseness and choking after thyroid cancer surgery, it is necessary to consult a doctor in time to determine whether there is any damage to the recurrent laryngeal nerve, and to standardize the treatment under the guidance of the clinician, rather than blindly using medication on one’s own.
