Overview
Causes
The exact cause is unknown, but most likely there is a viral or environmental trigger in genetically susceptible people that causes an immune reaction. The body's white blood cells mistakenly attack the insulin-producing pancreatic beta cells. There are several forms of diabetes. Type 1 diabetes is called juvenile or insulin-dependent diabetes. Type 1 diabetes can occur at any age, but it is most often diagnosed in children, adolescents, or young adults.
Insulin is a hormone produced by special cells, called beta cells, in the pancreas. Insulin is needed to move blood sugar (glucose) into cells, where it is stored and later used for energy. In type 1 diabetes, these cells produce little or no insulin. Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. The body is unable to use this glucose for energy. This leads to the symptoms of type 1 diabetes. Within 5 - 10 years, the insulin-producing beta cells of the pancreas are completely destroyed and the body can no longer produce insulin.
