Background: Thyroid disorders are the most common endocrine abnormality in the
world secondary to diabetes mellitus. Thyroid hormones are essential for growth,
neuronal development, reproduction and regulation of energy metabolism. It influences
the metabolism of all substrates including minerals. Many studies have shown that
mineral metabolism is frequently disturbed in thyroid disorders.
Materials and Methods: The study was conducted on sixty newly confirmed
hypothyroid cases based on the thyroid profile and sixty euthyroid cases were recruited
as controls. Blood samples were collected from all the patients for the estimation of
serum T3, T4, FT3, FT4, TSH, calcium, phosphorus and magnesium by auto analyzer
method. Modified spectrophotometric micro-method was used to measure Serum
copper using Bathocuprine Disulphonate Disodium Salt (BCDS) and Guanidine
hydrochloride salt. The Statistical software namely SPSS 18.0, and R environment
ver.3.2.2 were used for the analysis of the data.
Results: It was found that the levels of serum sodium, potassium and calcium were
significantly decreased in cases than the controls. Serum magnesium and phosphorus
were significantly elevated in cases than controls.
Conclusion: Serum calcium, magnesium and phosphorous levels are significantly
altered in patients having hypothyroidism. Thyroid diseases have wide spread systemic
manifestations including their effects on bone and mineral metabolism. Also thyroid
hormone affects the glomerular filtration rate, renal blood flow, tubular reabsorption
and excretion of minerals which have direct effect on Calcium, Magnesium and
phosphorous level. Thus monitoring of these minerals in hypothyroid patient will be of
great benefit in improving clinical manifestation and can be treated appropriately.
