Relationship of metabolic syndrome and its components with thyroid dysfunction in Algerian patients

Thyroid dysfunction was found in 59.3% (n = 42) patients, hypothyroidism (45.3%) was the major thyroid dysfunction followed by hyperthyroidism (14.0%). Overall, the prevalence of metabolic syndrome was 48.8% (n = 42). Subjects with hypothyroidism had significantly higher level of BMI, WC, TC, LDL-C, and higher prevalence of abdominal obesity (84.6%, p < 0.01) and hypertension (51.2%, p < 0.05). The hyperthyroid group had significantly lower level of TC, LDL-C and HDL-C but a higher level of SBP and UA. Furthermore, abdominal obesity, hypertension and low HDL-C level were the most common metabolic syndrome compounds found in the hyperthyroid group compared to the euthyroid group. We found a positive association between TSH level and the prevalence of the metabolic syndrome.
