What is the life expectancy with type 1 diabetes in Ohio?

A 10-year-old diagnosed with type 1 diabetes in Ohio in 2025 is expected to live to 64.7, compared with 78.5 for a 10-year-old without T1D: 13.8 years of life lost. Counting years lived with complications as well, T1D costs 22.3 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 15.3 years.
