What is the life expectancy with type 1 diabetes in Switzerland?
A 10-year-old diagnosed with type 1 diabetes in Switzerland today is expected to live to 67.2, compared with 84.5 for a 10-year-old without T1D: 17.4 years of life lost. Counting years lived with complications as well, T1D costs 34.3 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 13.7 years.
