What is the life expectancy with type 1 diabetes in the Dominican Republic?

Counting years lived with complications as well, T1D costs 33.1 years of healthy life at today's level of care. If everyone received timely diagnosis, insulin and test strips, and insulin pumps and CGMs, that loss would fall to 15.6 years.
