The bidirectional relationship between diabetes mellitus and liver disease: Mechanisms, clinical implications, and management strategies.

backgroundThe increasing prevalence of liver disease and diabetes mellitus in the global population highlights the importance of a complete and integrated understanding of their intricate, reciprocal relationship. The metabolic and clinical association between type 1 and type 2 diabetes mellitus and liver diseases such as cirrhosis, hepatitis, hepatocellular carcinoma (HCC), and metabolic dysfunction-associated steatotic liver disease (MASLD) is comprehensively reviewed

methodsThis review encompasses recent clinical, epidemiological, and molecular evidence addressing shared pathophysiologic mechanisms and emerging diagnostic and therapeutic approaches related to diabetes-liver disease interactions.

resultsThe evidence points to similar mechanisms like oxidative stress, insulin resistance, chronic inflammation, mitochondrial dysfunction, lipotoxicity, and activation of hepatic stellate cells. There are some conditions like hepatitis C infection and metabolic disorders that make insulin resistance and blood glucose levels worsen. Moreover, it hastens liver fibrosis and affects anti-viral drug efficacy. The available treatments include medication and lifestyle changes combined with molecular-based liver treatments and liver fibrosis and other AI-based diagnostic tools. There are some limitations to the available knowledge and science. For example, there is no vaccine to prevent HCV infection and liver fibrosis. There are also some social barriers like stigma that come with liver fibrosis.

conclusionTo reduce complications in individuals affected by diabetes and liver disorders, this article emphasizes the value of initiating early metabolic therapy, adopting integrative diagnostic methods, and pursuing personalized, multidisciplinary care.
