Perturbations in the actions of T 3 and T 4 influence the normal metabolic pathways. Responsiveness of lipid biomarkers like LDL- C, HDL-C, TC, TG, Apo-A, and Apo-B after rehabilitation of thyroid profile attaining euthyroid state was determined. A total of 179 age-matched subjects of both genders were recruited for this research. Sixty healthy controls, thirty-four subclinical, fifty overt hyperthyroid, and thirty-five follow-up subjects having 3 months of Carbimazole therapy were enrolled. Biochemical analysis was performed by chemistry analyzer, RIA, and ELISA. One-way ANOVA was applied for the statistical analysis, while significance (P <0:05) of means was compared by the Student-Newman-Keuls (SNK) test. Pronounced reduction (P <0:001) of cholesterol in overt as compared to control and subclinical was noticed, whereas marked improvement (P <0:001) was evidenced in follow-up. Prominent elevation (P <0:05) of TG in follow-up was evidenced as compared to control. Overt presented marked reduction of HDL-C as compared to subclinical and control (P <0:01 and P <0:001), respectively. Pronounced elevation (P <0:001) of HDL-C was evidenced after treatment. Overt presented reduction of LDL-C as compared to subclinical and control (P <0:01 and P <0:05, respectively). The follow-up group demonstrated considerable (P <0:001) improvement of LDL-C after treatment and elevation (P <0:05) as compared to control. Overt presented reduction of Apo-B as compared to subclinical and control (P <0:05 and P <0:001, respectively). Improvement (P <0:05) of Apo-B was evidenced in follow-up. Reduction (P <0:05) of Apo-A in overt as compared to control and elevation (P <0:05) in follow-up as compared to overt was evidenced. Conclusively, improvement after treatment was evidenced in lipid profile. 1. Introduction Thyroid hormones both tri-iodothyronine (T 3 ) and tetra- iodothyronine (T 4 ) or thyroxin are the most vital biomole- cules in the realm of thyroidology [1]. Both T 3 and T 4 are under the influence of thyroid-stimulating hormone (TSH) a glycoprotein, released by adenohypophysis that in turn is controlled by thyroliberin of the hypothalamus [2]. Levels of T 3 and T 4 in circulation execute a negative feedback effect on pars distalis of the pituitary to synthesize TSH, a regula- tory hormone, which later acts on the TSH receptor (TSH- R) situated on the cellular membranes of thyroid follicles [3]. TSH mediates iodine uptake, primarily through the actions of sodium/iodide symporter [4]. Overt or clinical hyperthyroidism is characterized by ele- vated serum free T 4 and T 3 levels in the presence of an undetect- able TSH concentration. Indications of hyperthyroidism are loss of weight, increased sweating, tremors of hands, weakness, increased appetite, accelerated heartbeat, loose stools, irritabil- ity, exophthalmos, heat intolerance, moist skin, and goiter [5]. Subclinical or asymptomatic thyroid disorder character- izes the initial phase of thyroid dysfunction [6].
