How long a patient can cook after thyroid surgery depends on the benignity or malignancy of the thyroid nodule, the size of the surgical trauma, and whether the patient has complications after surgery. 1. If the patient’s thyroid lesion is relatively small in scope and benign, such as thyroid cysts and thyroid adenomas. The scope of surgical excision is limited, the trauma is relatively small, and the patient does not suffer from complications related to incisional infection, hoarseness, or difficulty in swallowing after surgery. At this time, the patient needs to rest for 7-10 days to fully recover and cook. 2. If the patient’s thyroid nodule is larger in size and is a malignant tumor, the scope of surgical excision is larger, the patient has more severe neck trauma, and postoperative complications such as hoarseness, incisional fat liquefaction, infection, and hypocalcemic convulsions may occur. Patients often need a longer time to recover, taking 2-3 months to be able to cook normally.
