The level of thyroxine secretion increases, which is common in thyroid diseases such as hyperthyroidism, subacute thyroiditis, painless thyroiditis, and hyperthyroidism crisis. Thyroid hormone is a common indicator to judge hyperthyroidism, and can also be used as a therapeutic effect evaluation and monitoring of thyroid dysfunction. In clinical practice, it is often associated with FT4, FT3TT3, TSH and thyroid related antibodies are combined to diagnose thyroid related diseases. If only thyroxine is slightly elevated and other indicators are normal, you can regularly follow up thyroid function and thyroid color ultrasound. If both t3t4 and tsh rise and fall, further examination is required. After the possible diagnosis of thyroiditis or hyperthyroidism is ruled out, symptomatic treatment should be carried out according to the etiology.
