A metabolic syndrome, sometimes referred to as an X syndrome or a polymetabolic syndrome, is not a single ailment but a collection of interrelated factors that can contribute to the development of conditions such as type 2 diabetes and atherosclerosis. The likelihood of developing metabolic syndrome increases with age and is typically diagnosed in individuals over 60 years old.
Metabolic syndrome: A comprehensive definition, pathophysiological mechanisms, and clinical implications in the context of contemporary lifestyle-related diseases
Metabolic syndrome does not constitute a singular pathological entity but rather represents a multifaceted constellation of interrelated metabolic disturbances that collectively amplify the susceptibility to severe cardiovascular diseases and other systemic complications. The formalization of this concept occurred relatively late in the medical literature—specifically in 1981—through the seminal contributions of two German researchers, M. Hanefeld and W. Leonhardt, who were the first to systematically delineate its core components, etiopathogenic underpinnings, and long-term health ramifications. According to their findings, the primary predisposing factors include a sedentary lifestyle, genetic predispositions, and a chronic excess of dietary energy intake surpassing the body’s metabolic requirements. The syndrome’s hallmark features encompass pathological adipose tissue accumulation (particularly visceral fat), insulin resistance progressing to type 2 diabetes mellitus, elevated uric acid levels with an associated risk of gout, sustained arterial hypertension, and dyslipidemia characterized by an aberrant lipid profile. Among the most severe complications linked to this syndrome are accelerated coronary atherosclerosis (thereby precipitating ischemic heart disease) and an increased prevalence of cholelithiasis, as comprehensively documented in the original 1981 publications by Hanefeld and Leonhardt.
