Introduction : Metabolic syndrome is generally characterized as a clustering of the abnormal levels of blood lipids (low High Density Lipoprotein (HDL) and high triglycerides), impaired fasting glucose, elevated blood pressure and excess abdominal obesity. Objectives : To study the prevalence and type of thyroid dysfunction in a diagnosed case of metabolic syndrome. Material And Method: A complete physical and systemic examination was performed including CBC, RFT, Blood Glucose profile, Thyroid examination, complete urine. X–ray chest, USG–KUB, 2D–echo was performed in all cases. Results : The percentage of sub clinical hypothyroid was 21% and overt hypothyroid was 9%. Subclinical hypothyroidism and overt hypothyroidism were present in 26.66% and 11.66% of females and in 12% and 5% of males respectively. None of the patient had subclinical or overt hyperthyroidism. Conclusion : It can be concluded from the present study that sub clinical hypothyroidism and overt hypothyroidism is significantly associated with metabolic syndrome, especially females with metabolic syndrome have a higher prevalence of thyroid dysfunction which predisposes them to cardiovascular events. Therefore, we recommend the routine screening of the thyroid function in females with metabolic syndrome.
