 This study investigated the correlation between thyroid-stimulating hormone, TSH, levels and homocysteine, total cholesterol, and low-density lipoprotein, LDL, levels in hypothyroid patients. The results showed that TSH levels are significantly higher in hypothyroid patients compared to healthy individuals. Additionally, there was a positive correlation between TSH levels and homocysteine, total cholesterol, and LDL levels. These findings suggest that hypothyroidism may lead to increased levels of homocysteine, total cholesterol, and LDL, which could contribute to the development of atherosclerotic diseases.
