Diabetes and related metabolic disorders, including metabolic dysfunction-associated steatotic liver disease (MASLD), are increasingly recognized as diseases of inter-organ metabolic dysregulation rather than disorders of a single organ. The core of this process is the liver–pancreas axis, which integrates metabolic signals to maintain glucose and lipid homeostasis. Under physiological conditions, insulin and glucagon work together to regulate glucose production in the liver. The liver, in turn, regulates pancreatic β-cell function through hepatokines, metabolites and extracellular vesicles. Axis disorder driven by liver insulin resistance, lipid accumulation, inflammation or changes in hepatokine secretion exacerbates β-cell dysfunction, glucotoxicity and lipotoxic stress, thereby accelerating disease progression. This imbalance is involved in the pathogenesis of type 2 diabetes, type 1 diabetes, gestational diabetes, and monogenic diabetes, and makes MASLD a driving factor and early predictor of diabetes onset. This review summarizes the key molecular mechanisms behind liver–pancreas crosstalk and explores potential therapeutic strategies aimed at restoring coordinated metabolic regulation between the organs.
