To bring back normal TSH levels, different modalities may be employed depending on the patient’s age, concomitant conditions, and tolerability. This includes conventional oral medication, radiation, or surgery.
– Oral medication aims to target the thyroid and to relieve symptoms associated with hyperthyroidism. There are three antithyroid medications: Methimazole/Topazole, Carbimazole, and Propylthiouracil, and all directly halt the thyroid hormones production, leading to a boost in TSH secretion.
– They follow a daily regimen with a dose that will depend on the severity of the condition and will be maintained after reaching normal levels. Beta-blockers are added to antithyroid therapy to alleviate symptoms such as tachycardia and tremors.
– Another option is radioactive iodine therapy or ablation. The radioactivity from the orally administered iodine will directly destroy thyroid gland cells so fewer thyroid hormones are produced. It takes up to 18 weeks to reach full effectiveness, and sometimes therapy may require another course
– Surgery is a definitive cure for hyperthyroidism, reserved for patients who fail or cannot antithyroid and radioactive iodine therapies, and in those whose thyroid gland is too enlarged with a suspected malign tumor.
LH levels can sometimes fluctuate outside the normal range and will either decrease or increase, each having different causes and implications depending on the gender. Testing for LH level is done in concordance with FSH levels by drawing blood samples with lab kits. The test is ordered when the physician needs to investigate the reason behind irregular menstruation, inability to conceive, delayed or early puberty, or change in libido.
