Treatments for Low TSH Levels

By Taylor DiVico


Excessive amounts of thyroid hormones thyroxine and triiodothyronine affect the pituitary gland's production of the thyroid-stimulating hormone (TSH) by causing lower amounts of TSH to be secreted.


Low TSH levels potentially result from an enlarged thyroid, Graves' disease or thyroid nodules, leading to overactive thyroid and symptoms of fatigue, anxiety, weight loss, increased heart rate and heat sensitivity, requiring treatment.

Anti-Thyroid Medication

Anti-thyroid treatments are pills that provide ongoing therapy, allowing for a steady decline of hormones thyroxine and triiodothyronine, both of which cause low TSH when excessively secreted into the bloodstream.

Radioactive Iodine Therapy

Low TSH levels are raised through orally administered radioactive iodine that is absorbed by the cells of the thyroid gland, decreasing the size and activity of the thyroid.


A thyroidectomy is a surgical procedure in which the majority of the thyroid gland is removed to eliminate elevated levels of thyroxine and triiodothyronine, treating and increasing low TSH levels.
