METABOLIC SYNDROMEA syndrome is defined as "The aggregate of signs and symptoms associated with any morbidprocess,andconstitutingtogetherthepictureofthedisease".Themetabolicsyndromerepresentsa heterogeneous group of metabolic disorders, the central componentbeinginsulin resistance. It can involve multiple metabolicpathways thatresultsin dyslipidaemia, abdominal obesity, microalbuminuria and hypertension.The WHO has defined themetabolic syndrome as impaired insulin sensitivity, glucoseintoleranceordiabetesmellitusincombinationwithatleasttwoothermetabolicderangements, including abdominal obesity, dyslipidaemia (HDL-cholesterol levels and/orelevated plasma triacylglycerol (TAG) concentrations) and urinary microalbuminuria.TheNationalCholesterolducationProgramAdultTreatmentPanelIII(ExpertPanelonDetection, Evaluation, and Treatment of High Blood Cholesterol in Adults, 2001) have proposedthat individuals with the metabolic syndrome have three or more of the following metabolicderangements, including central obesity (waist girth >1020mm in men or >880mm in women),lowHDL-cholesterolconcentrations(<1.1mmol/lformenor<1.3mmol/lforwomen),hypertriacylglycerolaemia(>1.7mmol/l),hypertension(bloodpressure>130/85mmHg)orfasting hyperglycaemia (>6.1 mmol/l). Thus, the metabolic syndrome represents a genetically-heterogeneous group of metabolic disorders sharing insulin resistance.Abnormalities associated with the metabolic syndrome whichare as follows :-The core cluster
