Can sodium thyroxine treat central hyperthyroidism?

Hyperthyroidism refers to hyperfunction of the thyroid gland. Thyroxine sodium is generally available in tablet form, but this medication usually cannot treat central hyperthyroidism. If the body exhibits discomfort symptoms, it is recommended to seek medical attention at a hospital as soon as possible and follow the doctor's instructions for treatment.

Thyroxine sodium provides exogenous thyroid hormones, primarily intended to replace insufficient thyroid hormone levels in the body caused by hypothyroidism. For patients with central hyperthyroidism, the level of thyroid hormones in the body may already be excessively high. Hypothalamic or pituitary dysfunction can cause the thyroid gland to become overactive. In such cases, additional supplementation with thyroxine sodium may worsen the condition, leading to complications such as arrhythmia and osteoporosis.

The treatment of central hyperthyroidism should target its underlying cause—regulating the abnormal function of the hypothalamic-pituitary axis—rather than simply increasing or decreasing thyroid hormone supply. Antithyroid hormone synthesis inhibitors should be used to reduce thyroid hormone production. If a space-occupying lesion such as a pituitary tumor exists, surgical removal of part or all of the pituitary gland may be necessary to decrease thyroid hormone secretion.

Patients should also maintain healthy lifestyle habits and a positive mindset, actively cooperating with treatment to promote recovery.
