Thyroid function with high T3, T4 and FT3 is considered to have possible hyperthyroidism, which can be treated by medication, iodine 131 treatment and surgery.
Thyroid function generally includes thyroid stimulating hormone TSH, free thyroid hormone FT4, free triiodothyronine FT3, total thyroxine TT4, total triiodothyronine TT3. If TSH is significantly lower and T3, T4, FT4, FT3 is significantly higher, and at the same time, the patient has symptoms such as excessive sweating, irritability, and emaciation, it suggests the presence of hyperthyroidism.
1. Antithyroid medication: mainly applicable to mild and moderate hyperthyroidism, commonly used drugs such as propylthiouracil, methimazole, etc., to inhibit the synthesis of thyroxine. However, taking antithyroid drugs can cause adverse reactions such as hypogranulocytosis and skin itching.
2. Iodine 131 treatment: It is mainly applied to people with grade II enlargement or above of the thyroid gland, and people who are allergic to anti-thyroid drugs, and reduces the synthesis of thyroxine by destroying the thyroid tissue. Hypothyroidism may occur after the operation, and oral levothyroxine sodium is needed for symptomatic treatment.
3. Surgery: Thyroidectomy, unilateral or bilateral removal of the thyroid gland, can reduce the secretion of thyroxine and control the disease. It is suitable for patients with enlarged glands that may have symptoms of compression; moderate-to-severe hyperthyroidism that has been ineffective or inefficiently treated with long-term medication; nodular goiter with hyperthyroidism, and so on. Postoperative hypothyroidism may occur, requiring oral levothyroxine sodium replacement therapy.
It is recommended that patients with abnormal thyroid T3, T4, FT3 values, go to the regular hospital in time.
