Abstract:
Objective:To investigate the relationship between serum thyroid hormone levels in the normal range and body weight, blood glucose, blood lipids, and other obesity-related indexes in patients with type 2 diabetes mellitus.Methods:Seventy obese patients with type 2 diabetes mellitus and ninety-two patients with type 2 diabetes mellitus with normal weight who were treated in the Nangang Branch of Heilongjiang Provincial Hospital from May 2020 to May 2021 were included in this study. Thyroid-stimulating hormone level was in the normal range (0.35-4.94 mU/L) in all participants. Serum levels of free triiodothyronine, free thyroxine, thyroid-stimulating hormone, thyroid peroxidase antibody, thyroglobulin antibody, triglyceride, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, fasting blood glucose, glycosylated hemoglobin, fasting C peptide, fasting insulin, systolic blood pressure, diastolic blood pressure, and serum uric acid were measured in all participants.Results:Free triiodothyronine level was positively correlated with fasting blood glucose and glycosylated hemoglobin levels ( r = 0.19, P = 0.021; r = 0.21, P = 0.017). Free thyroxine level was positively correlated with serum glycosylated hemoglobin level ( r = 0.25, P = 0.009) and negatively correlated with total cholesterol ( r = -0.17, P = 0.029). Thyroid-stimulating hormone level was positively correlated with body mass index as well as total cholesterol and low-density lipoprotein cholesterol levels ( r = 0.33, P < 0.001; r = 0.33, P < 0.001; r = 0.32, P < 0.001). Conclusion:Thyroid hormones in the normal range play an important role in the regulation of body weight, blood glucose, and blood lipids in patients with type 2 diabetes mellitus. Blood glucose level increases markedly in patients with relatively high free triiodothyronine and free thyroxine levels. The risks of obesity and dyslipidemia increase in patients with relatively high serum thyroid-stimulating hormone levels
