If the hypothyroidism is caused by surgery and iodine 131 treatment, these two types of hypothyroidism do not have elevated autoantibodies, so you can eat the same diet as ordinary people and eat seafood at will. However, even if the hypothyroidism is caused by Hashimoto’s disease, during pregnancy, in order to synthesize the child’s thyroid hormone, it is necessary to consume iodine to ensure the supply of raw materials for the child’s thyroid hormone, otherwise, although the child’s thyroid function is normal, it may not be able to synthesize enough thyroid hormone because the mother does not supply iodine. This affects the child’s development, especially the development of the brain. At present, our thyroid scholars are studying the relationship between iodine intake and fetal development in early pregnancy and even before pregnancy. In addition to iodized salt, take a multivitamin containing 150 micrograms of potassium iodide (e.g. Kinselkamp or SunCure). If the increased iodine intake makes hypothyroidism worse, the doctor can increase the dosage of Eugenol, but the doctor cannot help because the mother’s low iodine diet refuses iodized salt and does not supply iodine to the baby, which prevents the baby from synthesizing thyroid hormones. Ordinary pregnant women, who do not have any thyroid disease, should also consume sufficient iodine for the sake of their child’s thyroid hormone synthesis. Please note that just taking more dietary supplements such as seaweed and nori seafood will not provide sufficient iodine. It is because studies have shown that iodized salt and potassium iodide contained in multivitamins can reach the fetus to ensure adequate supply of iodine to the baby, while iodine from food cannot reach the baby. Therefore, it is not possible to take iodine-containing food supplements without iodized salt and vitamins containing iodine. As long as you are pregnant, you must take iodized salt and a multivitamin containing 150 micrograms of potassium iodide (e.g., Kinselkamp or Sinclair, etc.) during pregnancy, as well as a multivitamin containing potassium iodide, if you are breastfeeding. In addition, for Hashimoto hypothyroidism or Hashimoto with normal nail function, these diseases are often lifelong, but also to clarify: for a person who likes seafood, it is quite a cruel thing to not allow seafood for life, eat seafood, even if the antibodies are elevated, hypothyroidism aggravated, that is, to increase the dose of some eugenol, therefore, if the patient with Hashimoto hypothyroidism thinks that, compared with more eugenol, enjoy the deliciousness of seafood Therefore, if a patient with Hashimoto’s hypothyroidism thinks that it is more meaningful to enjoy the taste of seafood than to eat more Eugenol, the doctor does not force to abstain from seafood.
