The Biochemical Symphony of Metabolic Syndrome: An Intricate Introduction

Metabolic syndrome (MetS) is a multifaceted public health threat characterized by a cluster of interconnected metabolic abnormalities, including insulin resistance, central obesity, chronic low-grade inflammation, and oxidative stress. The global prevalence of MetS varies significantly, influenced by factors such as gender, race/ethnicity, age, and socioeconomic status and has been on a steady rise. The development of MetS involves a combination of genetic and environmental factors that contribute to insulin resistance, abnormal hormonal signaling, and chronic low-grade inflammation. The definition and criteria for diagnosing MetS continue to evolve and are a topic of debate. Regardless of the specific diagnostic criteria, the presence of these metabolic abnormalities significantly amplifies the risk of cardiovascular disease and cancer. This chapter delves into the underlying mechanisms that contribute to the development and progression of MetS. Additionally, it explores the history of defining MetS and its diagnostic criteria.
