Metabolic syndrome (MetS), also termed insulin resistance syndrome, has been defined by World Health Organization (WHO) as a multi-factorial disorder characterized by a wide array of cardiometabolic risk factors that increase the risk of coronary heart diseases, diabetes mellitus, and stroke. The most common risk factors of MetS include dyslipidemia, abdominal obesity, insulin resistance, high systolic blood pressure, high triglyceride levels, impaired fasting glycaemia, low plasma adiponectin levels, and low high-density lipoprotein (HDL). However, it remains debatable whether these factors constitute a particular syndrome or are surrogate markers for MetS clustering in individuals at particular risk.
