What is the life expectancy with type 1 diabetes in Thailand?
A 10-year-old diagnosed with type 1 diabetes in Thailand today is expected to live to 43.8, compared with 77.7 for a 10-year-old without T1D: 33.9 years of life lost. Counting years lived with complications as well, T1D costs 41.2 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 16.3 years.
