Changes in Lipid Profile and Body Mass Index in Patients with Subclinical Hypothyroidism: Evaluation of L-Thyroxine Treatment

Abstract

Introduction: Subclinical hypothyroidism is defined as a mild elevation in serum thyroid stimulating hormone (TSH) level, while serum free T4 (FT4) and free T3 (FT3) levels are within the reference range. The main problem with these patients is whether they should receive therapy or not. In many studies, positive effects of levothyroxine treatment on hypothyroidism symptoms, serum lipid levels and cardiac functions are shown. In this prospective clinical study, we aimed to evaluate the metabolic changes in newly diagnosed subclinical hypothyroidism patients who were administered thyroxine.
