Male Health : Thyroid-Hormone-Suppressive Therapy With Levothyroxine

Levothyroxine or L-thyroxine may be a synthetic form of the thyroid hormone thyroxine. In its natural type, thyroxine is additionally in its L-form. This synthetic hormone is used as a supplement for hypothyroid patients who are incapable of manufacturing sufficient quantities of thyroid hormone to take care of normal physiologic functions.
Indications and Contraindications Around forty % of doctors recommend this artificial hormone for the treatment of solitary thyroid nodules however there are some instances when its administration is deemed inappropriate. One in all the factors to be thought-about in prescribing thyroid-hormone-suppressive therapy in a very patient with thyroid nodules is that the patient's age. Patients on top of the age of sixty years old and postmenopausal ladies are in danger for the adverse outcomes of this hormone. Additionally, benign thyroid nodules in advanced age are characterized by little growth if at all. Levothyroxine may be effective in diminishing the dimensions of tiny, recently diagnosed nodules with an abundance of colloid. It's been hypothesized that the hormone may aid in the prevention of the formation of more follicles however this has however to be verified. As a result of of this, it's generally not counseled for benign thyroid nodules.
Rationale: How It Works The activity of the thyroid gland is mostly stimulated by the secretion of thyroid-stimulating hormone or TSH by the pituitary gland. In cases of patients unable to react properly to the stimulus, the thyroid continues to swell as it gets even additional irritated despite its continued inability to supply sufficient quantities of thyroid hormone. Because there is still terribly very little concentration of thyroid hormone within the body, the pituitary gland continues to unharness additional TSH to up the thyroid hormone production but to no avail. This only causes additional follicles to grow in the thyroid without releasing any hormone at all. Administration of thyroxine or a artificial type of the hormone will not only provide relief from the symptoms of hypothyroidism, its presence will also signal the pituitary gland to secrete less and fewer of the thyroid-stimulating hormone. Without the unnecessary pressure exerted by increased levels of TSH to irritate the thyroid gland, it starts to recede in size.
Efficacy: Does It Work? There are conflicting studies on whether levothyroxine is indeed effective in shrinking benign thyroid nodules. One such study states that there was a significant result on patients when treatment with the hormone, whereas another would state that the hormone was ineffective. Another study indicates that treatment with the hormone resulted in a vital reduction in the thyroid nodules with consequent prevention in the formation of new nodules. A subset of benign thyroid nodules were found to react favorably in response to levothyroxine but the markers for this subset are nonetheless undefined. But, it's been observed that solid nodules do respond more to the hormone than cystic nodules. Also, smaller nodules and nodules filled with colloid are found to be plagued by the synthetic hormone.
