Whether or not patients with thyroid nodules can eat nori depends on the specific cause of the nodules. If a patient has a hyperthyroid nodule, if the patient eats a lot of nori, it will cause a significant increase in the level of thyroid hormones and increase the size of the thyroid nodule, which will aggravate the patient’s condition, because nori is rich in iodine. It is not advisable to eat nori at this time, but to control the stability of thyroid hormone levels through oral medication such as Sage to avoid further enlargement of the nodules. Second, if the patient is suffering from hypothyroidism, causing diffuse thyroid hyperplasia with nodules, the patient can eat nori to supplement iodine, which will help maintain thyroid hormone levels within the normal range and promote the nodules to subside, so you can eat nori in this case.
