High triglycerides a type of fat, or lipid, in the blood increase the risk of heart disease and perhaps type 2 diabetes. For the first time, it has been shown that profoundly lowering triglycerides in diabetics improves their insulin sensitivity over time, which helps them maintain healthy glucose - blood sugar levels. Volanesorsen, an experimental lipid-lowering medication, improved insulin sensitivity and glucose control by significantly decreasing patients' overall hemoglobin A1c the standard clinical measurement of blood glucose levels for diabetics in a new study reported by researchers from the Perelman School of Medicine at the University of Pennsylvania. The results are published online this month in Diabetes Care.
