Abstract


Background: Thyroid hormones have a vital role in metabolism of lipids, cholesterol etc. They also have an important role in phosphorous and calcium homeostasis by their direct effect on bone turnover. The objective of present study was to find the significant differences of T3, T4, TSH, lipid profile (HDL, LDL, vLDL, TG, Cholesterol), electrolytes and minerals (sodium, potassium, chloride, phosphorus, calcium) between control group and hypothyroidism patients.

Methods: Blood samples were collected from 72 patients and 12 control after their consent. Serum was used to determine biochemical parameters using standard protocol. Data obtained were statistically analyzed using “t” student test.

Results: The level of TSH was significantly higher in female and male hypothyroidism patients (p < 0.01) as compared to control and it was inversely related to the level of T3 and T4. Patients with hypothyroidism have increased level of LFTs profile especially cholesterol and Triglycerides levels both in males and females. In hypothyroidism, the level of glomerulus filtrate rate decrease especially sodium level but thyroid hormonal disturbance does not affect serum electrolyte level. The serum phosphorus and calcium levels change significantly in thyroid disorder.

Conclusion: Hypothyroidism is associated with increased TSH level and decreased T3 and T4 levels but does not appear to be associated with abnormalities in lipid profile. The serum phosphorus and calcium levels change significantly in thyroid disorder, Treatments of its primary causes should be given and if it is possible minerals can be added to avoid further bone complications.

Keywords: Hypothyroid; T3; T4, TSH; Lipid profile; Mineral
