Conditions InDepth: Type 1 Diabetes
Type 1 diabetes is a disorder usually caused by autoimmune destruction of the insulin secreting cells of the pancreas, resulting in the body’s inability to produce sufficient insulin to meet bodily needs. Insulin is a hormone produced by the pancreas that allows the body to use sugar (glucose) for energy. Without insulin, glucose from the carbohydrate foods you eat cannot enter cells. This causes glucose to build up in the blood, leaving your body cells and tissues starved for energy. While a variety of tissue transplantation techniques are under development and some genetically-based treatments have been proposed, at this point in time, the only widely-available treatments for type 1 diabetes are the injection of insulins and inhaled insulin.
