What is the life expectancy with type 1 diabetes in West Virginia?

A 10-year-old diagnosed with type 1 diabetes in West Virginia in 2025 is expected to live to 59.7, compared with 75.6 for a 10-year-old without T1D: 15.8 years of life lost.

If everyone received timely diagnosis, insulin and test strips, and insulin pumps and CGMs, that loss would fall to 16.0 years.
