Introduction: Subclinical hypothyroidism (SH); is a condition in which serum free T4 (fT4) levels are within normal limits and thyroid stimulating hormone (TSH) levels are above age-related levels. In obesity, serum TSH levels increase with the increase in body mass index; Thus, the frequency of SH is reported to be high in obese patients. Hypothyroidism and obesity are the main causes of secondary dyslipidemia. In this study; in overweight / obese children and adolescents; the frequency of SH and its relationship with lipid metabolism abnormalities were investigated.
