The cause of type 1 diabetes mellitus (DM) is unknown, however, current theory suggests that it occurs due to an autoimmune destruction of cells that make insulin (Diabetes Canada, 2013). Moreover, type 1 DM is a chronic disease caused by pancreatic insufficiency of insulin production, where the beta cell undergoes inflammatory damage. Insulin is an important hormone in the body that functions to control the level of glucose, or sugar, in the blood. Without insulin, glucose builds up in your blood instead of being used for energy (Diabetes Canada, 2013). Common food sources that produce glucose are foods like bread, milk, fruit, pasta, rice, and potatoes (Diabetes Canada, 2013). The characteristic result of beta cell destruction is hyperglycemia and end-organ complications (Nursing Central, n.d.). The age of onset peaks between 5 and 7 years and again around puberty (Nursing Central, n.d.).
