I will be running the NYC Marathon to raise money for JDRF. Type 1 diabetes strikes both children and adults at any age. As many as 3 million Americans have type 1 diabetes. Type 1 diabetes (T1D) is an autoimmune disease in which a person’s pancreas stops producing insulin, a hormone that enables people to get energy from food. It occurs when the body’s immune system attacks and destroys the insulin-producing cells in the pancreas, called beta cells. While its causes are not yet entirely understood, scientists believe that both genetic factors and environmental triggers are involved. Its onset has nothing to do with diet or lifestyle. There is nothing you can do to prevent T1D, and—at present—nothing you can do to get rid of it. Diabetes is the seventh leading cause of death in the United States. The risk of death for people with diabetes is about double that of people of similar age without diabetes.
