Metabolic syndrome is a multifaceted metabolic disorder characterized by a constellation of interconnected risk factors, including insulin resistance, abdominal obesity, dyslipidemia, and hypertension. These components collectively predispose individuals to an elevated risk of cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). The prevalence of metabolic syndrome has escalated globally, paralleling the rise in obesity rates and sedentary lifestyles. This review explores the pathophysiology underlying metabolic syndrome, emphasizing its role in the development and progression of CVD and T2DM. Epidemiological data underscore the substantial public health burden metabolic syndrome poses, necessitating effective preventive strategies and management approaches. The current diagnostic criteria and screening tools are discussed, highlighting their utility in clinical practice. Management strategies encompass lifestyle modifications, pharmacotherapy, and surgical interventions, each targeting specific components of metabolic syndrome to mitigate cardiovascular and metabolic risks. The challenges in diagnosing and managing metabolic syndrome are addressed alongside emerging research directions to enhance prevention and treatment outcomes. By elucidating the intricate relationship between metabolic syndrome, CVD, and T2DM, this review aims to guide healthcare practitioners in optimizing patient care and advancing public health initiatives to combat this pervasive syndrome.
