Type 1 diabetes is typically diagnosed in childhood and is due to an autoimmune condition that deconstructs the islet cells of the pancreas. Islet cells in the pancreas are responsible for insulin production. If there are not enough of these cells, there is not enough insulin being produced by the body in order to transfer glucose to the respective areas in order to be used for energy/fuel.
People diagnosed with Type 1 diabetes get their insulin from either an insulin pump or numerous injections of insulin throughout the day.
Only 5% of people who have diabetes have Type 1 diabetes.
