More young women in their 20s are getting type 2 diabetes
Researchers said obesity is pushing diagnosis rates up 69% in women ages 20 to 29, while cases are falling among older adults.
Imperial College London researchers analyzed type 2 diabetes cases across England from 2011 to 2024, finding incidence rose rapidly in people under 40, with age-standardised incidence increasing 69% in women aged 20 to 29.
BMI at diagnosis rose about 5–7% in adults under 40 compared with only 2–3% in older adults. Clinical associate professor Shivani Misra said this suggests successive generations are developing type 2 diabetes at increasingly severe obesity levels.
Among younger people, the rise is occurring across all ethnicities but is particularly noticeable in white, Asian, and black women aged 20 to 29, and in white women aged 30 to 39.
Type 2 diabetes guidelines this year now recommend early GLP-1 treatment for young adults. However, researchers warned insufficient evidence exists on whether drugs like Ozempic or Wegovy at scale can sustainably prevent the disease long-term.
Helen Kirrane, head of policy at Diabetes UK, warned type 2 diabetes is more aggressive in younger people. Experts advocate stronger public health measures, including restricting unhealthy food marketing, to address the obesogenic environment driving rising cases.
