Results of recent studies using standard long and short acting insulin therapy (Basal - Bolus or BBI) in type 2 diabetes mellitus (T2DM) have not shown benefits to lower risks for heart attacks, strokes, or eye, nerve and kidney problems. Some studies also show a long time between the start of treatment and signs of benefit. This has led to a review of current ways to normalize blood glucose control with basal bolus insulin and how to make blood glucose better. Improving blood sugar with insulin therapy usually causes weight gain, more high sugar levels after meals, and more low blood sugars. Early studies suggest that when people take long-acting insulin and metformin, they have fewer blood sugar extremes when they also take a new type of medicine called glucagon-like polypeptide-1 (GLP-1) agonist named exenatide (Byetta), instead of meal-time insulin. This means there might be a better way to treat Type 2 diabetes.
