Metabolic associated steatotic liver disease is a contemporary academic concept and research field focused on liver conditions characterized by excessive fat accumulation (steatosis) in hepatocytes, specifically linked to metabolic risk factors such as obesity, type 2 diabetes, dyslipidemia, and metabolic syndrome. This concept investigates the complex interplay between metabolic dysfunction and hepatic pathology, exploring its epidemiology, pathogenesis, diagnostic criteria, clinical progression, and therapeutic strategies, recognizing its significance as a global public health challenge and a key component of systemic metabolic disease.
