Kidneys
Diabetes is the number one cause of chronic kidney (or renal) failure in the U.S., and kidney disease among people with diabetes has more than doubled in the past decade. According to the National Kidney Foundation, approximately 30% of people with long-term type 1 diabetes (about one in three) will develop kidney disease. The good news is that with early detection and proper treatment, kidney disease can be slowed and, in some cases, reversed.
