2. Causes

Type 1 diabetes is an autoimmune disease, and its exact origin is unknown. Autoimmune diseases are those that cause the immune system to attack the body mistakenly. In the case of type 1 diabetes, the body attacks and destroys islet cells in the pancreas. Once enough of those cells are gone, the body ceases the production of insulin. Because insulin lowers the amount of sugar in the bloodstream, lack of it can cause these sugars to build up, leading to life-threatening complications.
