Nearly half of adults worldwide with diabetes dont know they have the disease, study finds

Nearly half of adults worldwide who are living with diabetes dont even know they have it, leaving millions vulnerable to dangerous complications. A sweeping new study, published in the journal The Lancet Diabetes & Endocrinology, examined data from more than 200 countries between 2000 and 2023, tracking how well health systems identify, treat and control the condition. Researchers analyzed how many people with diabetes are undiagnosed, untreated, receiving suboptimal care or achieving optimal blood sugar control, broken down by age, sex, location and year. The researchers found that about 44% of people aged 15 and older with diabetes remain undiagnosed.
