What Is Diabetes?
Diabetes means that your
blood glucose (GLOO-kos), also called blood sugar, is too high. Glucose comes from foods we eat, and is needed as fuel for our bodies even when we are at rest. Your blood always has a little bit of glucose. Extra glucose is normally stored in our liver and muscles until we need it for activity. To be used for energy the glucose has to be moved from the liver, muscle and blood into the cells. The problem happens when the glucose stays in your blood and does not reach the cell. This causes your blood glucose to reach an unhealthy level.
An organ in our body, the pancreas (PAN-kree-as), makes
insulin (IN-suh-lin). Insulin is what helps glucose move from the blood into the cells. When you have diabetes, it is because the pancreas does not produce enough insulin. Another type of diabetes is caused when the pancreas makes insulin, but the cells are not using the glucose very well. In both cases, the blood glucose level rises too high. It is unhealthy for the blood glucose to be too high. This elevation in blood glucose level causes damage to the heart, blood vessels, eyes, nerves and kidneys.
