1. Q: What kind of salt do I eat after total thyroidectomy? A: It does not matter if the salt contains iodine or not as long as no radioactive iodine treatment is done. Note: Because the role of iodine found in the human body is to synthesize thyroid hormone, and patients after total thyroidectomy, regardless of whether the pathology is benign or malignant, definitely need to take eugenol to replace thyroid function, therefore, taking or not taking iodine has no effect on patients after total thyroidectomy. If total thyroidectomy is performed for cancer and radioactive iodine therapy is required after surgery, it is a different matter. Preparation for radioactive iodine therapy requires a low iodine diet, as detailed in this public platform for radioactive iodine therapy. 2.Q: Is hypothyroidism curable? A: It can be corrected by simple supplementation of thyroxine. Q: But you need to take medication for life? A: Depends on how you think, isn’t it the same for patients with high blood pressure? Wouldn’t it be nice to be able to act like a normal person through a very cheap and easy method? Note: There are many causes of hypothyroidism, it may be low thyroid function due to Hashimoto’s thyroid inflammation, or it may be underactive thyroid function due to surgical removal. It is difficult to recover after the occurrence of hypothyroidism, for example, it is almost impossible to recover from hypothyroidism caused by surgical removal. Hashimoto’s disease is an autoimmune disease, and it is not easy to recover, and the incidence is still very high. But in any case, the treatment of hypothyroidism is very simple, oral eugenol can be supplemented with normal thyroid function, eugenol and the body’s own secretion of thyroid hormone has the same chemical molecular formula, normal supplementation rarely has side effects, some people say, in fact, is to put the thyroid gland into their own “pocket”. This analogy is very visual and easy to understand.
