In the United States, an estimated 29.1 million people or 9.3% of the population have diabetes. According to a 2014 summary report from the Centers for Disease Control and Prevention, this includes 21 million people who have been diagnosed with the disease and more than 8 million people who are undiagnosed. Diabetes is a disease in which blood glucose levels are above normal. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. When you have diabetes, your body either doesn't make enough insulin or can't use its own insulin as well as it should. This causes sugar to build up in your blood. Diabetes can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations. Diabetes is the seventh leading cause of death in the United States.
