Metabolic syndrome (Mets) is associated with endocrine disorders including thyroid dysfunction. Thyroid dysfunction in MetS patients adds to chronic diseases thereby increasing mortality. The present case control study was undertaken to determine the impact of thyroid dysfunction on MetS and finding the risk factor of Mets.



The present study consisted of 600 subjects, 300 each cases and controls of MetS. Information on demographics, clinical profile and laboratory parameters like age, gender, blood pressure, blood sugar, cholesterol level, etc. were collected in both cases and controls. Mean levels of thyroid function parameters between cases and controls were compared using T test and binary logistic regression was used to find the risk factors of MetS.


The levels of T3, T4 TSH, FT3, FT4 are significantly different between cases and controls whereas age, body mass index are same in cases and controls. Thyroid dysfunction was seen in 54.7% (n = 300) MetS patients. Subclinical hypothyroidism (24%) was the major thyroid dysfunction followed by hypothyroidism (18.33%), hyperthyroidism (6.67%) and subclinical hyperthyroidism (5.67%). T3, T4, TSH and FT3 came out to be as risk factors of MetS and FT3 was a protective factor (β=-0.681).



Thyroid dysfunction causes metabolic syndrome.
