The exact cause of type 1 diabetes is unknown. This leads to the symptoms of type 1 diabetes. The body is unable to use the glucose for energy. This buildup of glucose in the blood is called hyperglycemia.
Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. With type 1 diabetes, beta cells produce little or no insulin. Inside the cells, glucose is stored and later used for energy. Insulin is needed to move blood sugar (glucose) into cells. The pancreas is below and behind the stomach. Insulin is a hormone produced in the pancreas by special cells, called beta cells. It is most often diagnosed in children, adolescents, or young adults.
