How gut and liver interactions relate to diabetes and possible treatments

AI simplified

Abstract

Disruption of the gut-liver axis is associated with significant metabolic dysfunction in diabetes.

  • Gut microbiota dysbiosis and impaired intestinal barrier function may contribute to insulin resistance and hepatic steatosis.
  • Increased gut permeability is linked to pro-inflammatory signaling that affects glucose metabolism.
  • Emerging pathways involving neuroendocrine circuits and microbial metabolites could play a role in gut-liver interactions.
  • Therapeutic strategies targeting the gut-liver axis include microbiota modulation and anti-inflammatory interventions.
  • Challenges such as patient heterogeneity and lack of reliable biomarkers may hinder clinical translation of these therapies.
