High thyroid indicators should be treated by adjusting the diet and reducing the intake of iodized salt, as well as by taking medication. High thyroid indicators refer to high T3 and T4 levels, which can lead to high thyroid hormones in the body and cause abnormalities in the function of other target organs in the body. Timely treatment with medications such as methimazole is needed to effectively act on the thyroid gland to reduce thyroid hormone levels and also to increase the negative regulatory effect of the pituitary gland. Subsequently, iodination can also be administered. The combination of both treatments can consolidate the efficacy and effectively control clinical symptoms. High thyroid indicators require continuous treatment, and if the effect is not obvious, local removal of the thyroid gland may be considered, which can also cure the condition.
