Diabetes来源：考试大
Most of the food we eat is turned into glucose for our bodies to use for energy. The pancreas, an organ near the stomach, makes a hormone called insulin to help glucose get into your body cells. When you have diabetes, your body either doesn't make enough insulin or can't use its own insulin well. This problem causes glucose to build up in your blood.
