What is the life expectancy of someone with diabetes?

On average the life expectancy of a person with type 1 diabetes is shortened by 15 years.  However, each person’s experiences of living with type 1 diabetes are unique.  Diabetes is difficult to deal with and the potential consequences are extremely concerning, but research has already led to great improvements in treating diabetes and quality of life and future advances in technology and research will eventually result in diabetes being curable.
