There is no absolute dietary contraindication after unilateral thyroidectomy, but it is necessary to control iodine intake according to the condition of the patient, and at the same time, quit smoking and limit alcohol, and avoid eating food that is not easy to swallow and irritating before the wound heals. 1. Control of iodine intake: after unilateral thyroidectomy, thyroid function may be affected to some extent. If you have hyperthyroidism before surgery, it is recommended to reduce the intake of iodine-containing foods, such as seaweed and seafood. 2.
