Abstract
This article evaluates the relationship between thyroid hormone levels, including TSH, fT4, T4, T3, and lipid profiles, such as total cholesterol, LDL, and HDL, in obese individuals compared to healthy ones. The research included 80 individuals, of which 40 were categorized as obese (20 males and 20 females) and 40 were healthy controls (also 20 males and 20 females). All participants were between the ages of 25 and 45. To perform thyroid gland tests, blood samples of 10 ml were taken from both healthy and subjects participants without EDTA and put into test tubes. The plain tube containing blood was centrifuged to separate the serum for further thyroid function and chemical tests. The ELISA device was used following the manufacturer's instructions. The study found significant differences in the levels of TSH hormone between subjects and healthy participants based on the collected data. Furthermore, subjects had significantly lower levels of fT4 hormone in subjects (4.4±2.0) compared to healthy controls (8.1±2.1). The research findings indicated a significant reduction in T4 hormone levels (4.3±1.3) in subjects, which was consistent in both males and females and corresponded with the increase in TSH hormone levels (9.17±2.0) observed in subjects individuals compared to healthy subjects (2.98±2.1).However, there were no significant alterations in T3 hormone levels among subjects when compared to healthy individuals. Hence, the study concludes that there is a definitive correlation between hypothyroidism and obesity.
