    Type 2 diabetes mellitus (T2DM) is linked to gut microbiota disruptions that affect intestinal integrity, immune control, and insulin signaling.

  • 2

    Reduced butyrate-producing bacteria and increased opportunistic pathobionts contribute to gut dysbiosis in T2DM, leading to inflammation.

  • 3

    Increased intestinal permeability allows lipopolysaccharides to activate inflammatory pathways, disrupting insulin signaling and promoting insulin resistance.

  • 4

    Short-chain fatty acids (SCFAs) are crucial for insulin sensitivity, and their decreased production in T2DM weakens glucose uptake and enhances inflammation.

  • 5

    Dysbiosis creates a feedback loop of inflammation and metabolite imbalance, exacerbating insulin resistance and highlighting potential treatment targets.
