Thee Critical Intersection of Diabetes andLipid Metabolism

To fully graciate metformin 's role in lipid management, it is essential to understand thee criteristic lipid inormalities associated with insulin resistance and d hyperglycemia. This condition, known a s diabetic dyslipidemia, is a major disr of atherosclerotic CVD. Unlike primary hypercholesterolemia, diatic dyslipidemia is specized by a specific triad of lid enginees:

  • Xi1; Xi1; FLT: 0 = 3; Xi3; Elevated Triglicerydes (TG): Xi1; Xi1; FLT: 1 = 3; Xi3; Insulin resistance leads to o increaged lipolisis in adipose tissue, releasing free faty acids (FFAs) into the crimation. The liver takes up these excess FFAs, stimulating thee overproduction of verylow- density lipoproteins (VLDL), which are rich in triglicerydes.
  • Reduced High- Density Lipoprotein Cholesterol (HDL- C): demand1; demand1; FLT: 1 X3; EDCT3; EDCT3; The Metabolism of TG- rich lipoproteins alters cholesteryl ester transfer protein (CETP) activity, leading to the uduction of cholesterol from HDL particles andd accelegated clearance of HDL from the bloostream.
