Understanding type 1 diabetes

The cause of type 1 (T1D) diabetes is still a medical mystery with no cure (yet).1 What is known is that it’s an autoimmune disease unrelated to eating too much sugar or not exercising.It’s not caused by anything a person did or didn’t do. Anyone, at any age, can develop T1D, although it’s most often diagnosed in children, teens and young adults2 (in the past it was referred to as juvenile diabetes). While a diagnosis may feel overwhelming, type 1 diabetes doesn’t define who a person is. It’s just one aspect of daily life that can be successfully managed.
