Low thyroid hormone levels; low thyroglobulin levels

Medically, low thyroid hormone levels refer to hypothyroidism. Patients with hypothyroidism typically exhibit low thyroglobulin (Tg) levels, commonly resulting from iodine deficiency or insufficient thyroid hormone synthesis. It is recommended that patients receive pharmacological treatment under the guidance of a physician.

Thyroglobulin is a glycoprotein secreted by thyroid follicular epithelial cells and serves as an indicator of thyroid tissue mass. The concentration of thyroglobulin also reflects the structural integrity of the thyroid gland. When patients present with both hypothyroidism and low thyroglobulin levels, it is usually because reduced thyroid hormone production in hypothyroidism leads to decreased thyroglobulin synthesis. Under medical supervision, patients may be prescribed medications such as thyroid tablets or levothyroxine sodium tablets to restore thyroid hormone levels—and consequently, thyroglobulin levels.

Note: Patients should undergo regular follow-up visits at the hospital to monitor thyroglobulin levels, which facilitates assessment of therapeutic response and supports recovery.
