Advancing precision medicine in metabolic dysfunction-associated steatotic liver disease

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease (NAFLD), has become a pressing global health concern. The complexity of MASLD and the lack of universally effective treatments expose the limitations of current interventions, which focus mainly on lifestyle modifications. Here, we explore the multilayered nature of MASLD, emphasizing its pathophysiology in shaping future medical and lifestyle interventions from a personalized medicine perspective, based on individual molecular profiles. Additionally, we address the limitations of current animal models in reflecting human metabolic syndrome and sex-specific differences. We argue that a holistic approach, integrating social determinants of health, patient preferences, and adherence patterns, is essential for advancing MASLD management effectively.
