Our bodies need fuel for proper function. Glucose (sugar) is the fuel that our cells use to produce energy. In order to process the sugar we eat in various foods, our bodies produce insulin. Insulin is a hormone made by beta cells, clusters of cells in the pancreas (an organ located in the upper abdomen). In type 1 diabetes, the beta cells in the pancreas are unable to make insulin because of autoimmune disease. This means that the body's immune system makes autoantibodies that attack and destroy the pancreatic beta cells. Type 2 diabetes is the result of the body's not being able to properly use the insulin made by the pancreas, and it occurs in adults and children who are overweight. Because type 1 diabetes usually starts in childhood, it is sometimes called juvenile diabetes. Type 1 diabetes is a serious illness that cannot be cured, but it can be treated and controlled.
