Metabolic diseases, particularly diabetes mellitus, significantly increase hepatic vulnerability to injury from drugs, toxins, and ischemic or inflammatory stress. Diabetic livers are characterized by insulin resistance, dysregulated lipid and glucose metabolism, chronic low-grade inflammation, oxidative stress, and altered mitochondrial function, creating a permissive environment for hepatocellular damage. These metabolic derangements disrupt normal hepatocyte adaptive mechanisms, reduce antioxidant defenses, and promote pro-inflammatory signaling, rendering the liver more susceptible to injury. Clinical and experimental evidence demonstrates that diabetic individuals exhibit increased incidence and severity of drug-induced liver injury, nonalcoholic steatohepatitis progression, and ischemia-reperfusion damage. Understanding the mechanisms underlying this heightened vulnerability, including mitochondrial dysfunction, endoplasmic reticulum stress, lipotoxicity, and altered immune responses, provides a foundation for risk stratification, preventive strategies, and therapeutic interventions. This review synthesizes current knowledge on the impact of metabolic disease on liver susceptibility, highlighting mechanistic pathways and clinical implications, and underscores the need for targeted approaches to protect the diabetic liver from injury.

Keywords: Diabetes mellitus, hepatic vulnerability, oxidative stress, mitochondrial dysfunction, lipotoxicity.
