Whether to take iodized salt or non-iodized salt for high thyroid stimulating hormone depends on what the primary disease is. If high thyroid stimulating hormone is caused by pituitary tumor, then non-iodized salt is needed, if high thyroid stimulating hormone is caused by hypothyroidism due to iodine deficiency, then iodized salt can be taken, and it is recommended to consult with doctor. 1. Pituitary tumor: thyrotropinoma in pituitary tumor, because of its endocrine function, can secrete a large amount of thyrotropin, so it can further activate the thyroid gland, which is located in the lower position of the hormone axis, to produce a large amount of thyroid hormone, and then it is necessary to limit the intake of iodine. 2. Hypothyroidism caused by iodine deficiency: Iodine is the raw material for synthesizing thyroid hormones, and iodine deficiency may cause hypothyroidism. In this case, there is usually no need to avoid iodine diet and iodized salt can be consumed. If the patient is found to have high thyroid stimulating hormone, please follow the doctor’s instructions to make dietary adjustments.
