Diabetes is a chronic disease in which the body does not make enough insulin or does not properly use insulin to keep up with the amount of sugar in the blood. Your body changes most of the food you eat into glucose (sugar) and, through the blood stream, uses it to give your body energy. However, too much glucose in the blood is not good for your health.
When you eat, your blood takes the glucose to the cells throughout your body. The glucose needs insulin to get into the body's cells. Insulin is a hormone made in the pancreas, an organ near the stomach, and the pancreas releases insulin into the blood. Insulin helps the glucose from food get into the cells. If your body does not make enough insulin or the insulin does not work right, the glucose can't get into the cells, so it stays in the blood. This makes your blood glucose level high, causing you to have diabetes.
