| Summary: | Introduction: Hypothyroidism, one of the most common thyroid
gland disorders, can cause electrolyte disturbances in the body.
Hypothyroidism can alter mineral metabolism by changing
the levels of serum calcium and magnesium. Therefore, it is
essential to study any abnormalities in calcium and magnesium
metabolism in patients with hypothyroidism.
Aim: The aim of this study was to assess the levels of calcium
and magnesium in patients with hypothyroidism and to study
the correlation between Thyroid Stimulating Hormone (TSH),
fT3, and fT4 with calcium and magnesium in subclinical and
Overt Hypothyroidism (OH).
Materials and Methods: This cross-sectional study was
held from August 2019 to January 2020 in the Department
of Biochemistry, BS Medical College, Bankura. A total of 150
subjects were included in the study, distributed equally among
three groups: euthyroidism, subclinical hypothyroidism, and
OH. Serum TSH, fT3, fT4, calcium, and magnesium levels
were determined in the laboratory, and the data obtained
were statistically analysed using ANOVA test and Pearson’s
correlation test.
Results: Out of a total of 150 subjects, 61 were female, among
whom 23 had subclinical hypothyroidism and 21 had OH. There
were significant differences in the mean levels of TSH, fT3, fT4,
calcium, and magnesium between the SCH, OH, and euthyroid
groups. The study showed that the mean serum calcium level
was significantly lower in SCH and OH compared to euthyroids,
while the level of serum magnesium was significantly increased
in SCH and OH compared to euthyroid. There was a statistically
significant negative correlation between TSH and serum calcium
in both OH and SCH, while a statistically significant positive
correlation was observed between TSH and serum magnesium
levels in both groups.
Conclusion: The present study revealed that serum magnesium
levels were high while serum calcium levels were low in both
subclinical hypothyroidism and OH when compared to euthyroid
subjects. Additionally, calcium levels negatively correlated with
TSH, while magnesium levels positively correlated with TSH levels. |
