What is the life expectancy with type 1 diabetes in Texas?
A 10-year-old diagnosed with type 1 diabetes in Texas in 2025 is expected to live to 67.3, compared with 80.0 for a 10-year-old without T1D: 12.7 years of life lost. Counting years lived with complications as well, T1D costs 21.8 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 14.9 years.
| Level of care | Healthy years restored | Healthy years of life | Healthy years still lost |
|---|---|---|---|
| Current level of care | โ | 58.2 | 21.8 |
| + Timely diagnosis for everyone | โ | 58.2 | 21.8 |
| + Insulin and test strips for everyone | +1.2 | 59.4 | 20.6 |
| + Insulin pumps and CGMs for everyone | +5.7 | 65.1 | 14.9 |
