Diabetes Statistics

Diabetes is far more than a lab result, from 14.8% of US pregnancies affected by diabetes to $327 billion in 2017 healthcare costs split between diagnosed and undiagnosed disease. You will also find why newer monitoring and drug trials are shifting outcomes, alongside the global toll of 6.7 million diabetes related deaths and what that means for life expectancy and treatment gaps.

Diabetes is no longer just a health issue measured in blood sugar. In the US, diabetes-related medical costs reached $106.9 billion in 2022, while a growing share of pregnancies are also affected, with gestational diabetes impacting 14.8% of pregnancies from 2016 to 2020. The picture gets even sharper worldwide as prevalence, spending, and treatment gaps vary across countries, from 3.2 million people known to have diabetes in England in 2022 to 7.2% of pregnancies affected in Australia in 2018.
