Criteria for the diagnosis of metabolic syndrome: A review

Metabolic syndrome (MetS) consists of multiple, interrelated risk factors of metabolic origin that appear to directly promote the development of cardiovascular events and type 2 diabetes (T2D). It confers 2-fold increase in relative risk for atherosclerotic cardiovascular events and 5-fold increase in risk for development of T2D as compared with people without the syndrome. T2D is one of the most prevalent and serious metabolic diseases in the world, and among middle-aged men CHD is still the leading cause of mortality in western countries. Definitions of MetS vary widely with experts resulting in inconsistent diagnosis and inappropriate management. Consistent definition of the MetS and its feature would facilitate research into its causes and may facilitate its treatment. This review made a critical assessment of the criteria and suggested a way forward. Literature search between 2000 and 2022 was conducted and 60 publications including the author’s works were evaluated. From the review, it was established that both IR and obesity can give rise to all the risk factors and to each other. Therefore, if efforts are made to streamline the diagnosis of IR and obesity, there may not be need for the other varying specifications and criteria of universal application could emerge.
