There is no food that can not be eaten after thyroid surgery, but it is not recommended to eat hard food (such as nuts, apples, etc.), spicy and stimulating food (cola, hot pot, etc.), and food that is too hot and too cold (hot water, hot noodle soup, ice cream, etc.). Because of the obvious wound near the thyroid gland after thyroid surgery, eating hard food and spicy food (such as nuts, apples, cola, hot pot, etc.) will easily irritate the wound, which will lead to bleeding, dislodging of local sutures, etc., and in serious cases, it may also compress the normal trachea, which is not conducive to the patient’s ability to swallow, breathe and speak. Postoperative thyroid patients should also try not to eat too hot too cold food (such as hot water, hot noodle soup, ice cream, etc.), so as not to cause unnecessary stimulation of the thyroid gland, diet, try to choose easy-to-digest semi-liquid food, such as millet porridge, milk and other foods. Thyroid patients should consult a professional doctor in time when they experience discomfort after surgery to avoid other discomforts.
