Most of the food we eat turns into glucose or sugar for fuel. Digested food moves from the gut into blood vessels so it can travel to all parts of the body. A hormone called insulin ``unlocks'' cells so that glucose from the blood can enter cells throughout your body where it serves as fuel. Insulin is produced by the pancreas when glucose levels in the blood increase. In diabetes, there are problems with how insulin is made or works. When insulin does not move glucose from blood into cells, blood sugar levels stay high while your cells cannot get enough fuel. There are 2 main types of diabetes. In type 1, the pancreas does not make insulin and a person must take insulin to stay alive. In type 2, the most common type, either the pancreas does not make enough insulin or it is not effective at moving sugar into cells.
