The most common cause of kidney failure in the United States and across the world is diabetes mellitus (DM). Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in persons with diabetes, and chronic kidney disease (CKD) further increases overall CVD risk. It is important to individualize glycemic targets for patients to maintain glucose levels that will reduce the development and progression of complications while avoiding hypoglycemia. CKD alters the relationship of glucose levels to measures of long-term control, such as hemoglobin A1c.
