                                 Thyroid hormone

Thyroid hormone (triiodothyronine (T3) and thyroxine (T4)), produced by the thyroid gland, plays an important role in regulation of metabolism, including directly boosts energy metabolism and triggers rapid protein synthesis and regulates mitochondrial gene transcription, etc. Iodine is necessary for the production of T3and T4, deficiency of Iodine can lead to enlarge thyroid grand and goitre.

     Thyroid hormone: Subclinical hypothyroidism treatment?

Subclinical thyroid dysfunction is characterized by normal levels of thyroid hormones but abnormal values of thyrotropin (TSH) in an asymptomatic individual. It is a common disorder with a prevalence of about 7 to 8% in women (most frequently in females over 50 years), and about 3% in men. In the study of Is there a need for treatment in subclinical hypo- and hyperthyroidism?, researchers indicated that most frequently, this disorder is caused by exogenous L-thyroxine treatment. The endogenous form of subclinical hyperthyroidism mainly caused by nodular goiter has a prevalence of up to 20% in patients with large goiters. In patients with subclinical hyperthyroidism, there is an increased risk for development of atrial fibrillation and for a decrease in bone mass in postmenopausal women. In the majority of patients measurable TSH levels can be detected before or after stimulation with TRH. This formally excludes overt hyperthyroidism in such patients. Frequently, there is no need for treatment but follow-up is important. However, in patients with subclinical hyperthyroidism associated with atrial fibrillation a therapy with antithyroid drugs, beta-blockers or radioiodine must be considered(53).
