Probability of Developing Type 2 Diabetes
1 in 2.75 (36.4%)
Lifetime probability in US
More than 1 in 3 Americans will develop type 2 diabetes in their lifetime, with rates increasing due to obesity trends.
The lifetime risk of developing type 2 diabetes for Americans born in 2000 or later is estimated at approximately 36.4% (roughly 1 in 2.75), according to CDC research. This represents a significant increase from previous generations, driven largely by rising obesity rates.
The strongest modifiable risk factor for type 2 diabetes is excess body weight, particularly abdominal obesity. Other risk factors include physical inactivity, family history, age (risk increases after 45), race/ethnicity (Hispanic, African American, Native American, and Asian American populations have higher rates), gestational diabetes history, and polycystic ovary syndrome.
Type 2 diabetes is largely preventable. The landmark Diabetes Prevention Program study showed that moderate weight loss (5-7% of body weight) and 150 minutes per week of physical activity reduced the risk of developing diabetes by 58% in high-risk individuals. Early detection through fasting glucose or A1C testing allows for management before serious complications like kidney disease, vision loss, and nerve damage develop.
