( 3 ). Free triiodothyronine (FT3) is the bioactive form of thyroxines. FT3 regulates basal metabolic rate, promotes fat decomposition and acts on the cardiovascular system through adrenergic signaling ( 4 ). Previous studies have found that a high

Introduction The thyroid gland experiences great stress during pregnancy, increasing about 10–40% in size, with the production of thyroxine (T4) and triiodothyronine (T3) surging by 50% ( 1 ). As a result, thyroid dysfunction such as
