Nearly Half of Global Diabetes Cases Undiagnosed, UK Lags in Europe

A global study published in The Lancet Diabetes & Endocrinology reveals that nearly 44% of people aged 15 and older with diabetes remain undiagnosed worldwide, with the UK among the worst-performing high-income countries in diabetes diagnosis. The UK has a diagnosis rate of 74.2%, lower than the average 79.5% for high-income nations, and lags behind countries like Canada and the US, where diagnosis rates are 86% and 82.8% respectively. The study highlights that younger adults under 35 are particularly underdiagnosed, with only about 20% aware of their condition, partly due to less routine screening for this age group. Although 91% of diagnosed individuals globally receive treatment, only about 42% of those treated have optimal blood sugar control, resulting in just 21% of all people with diabetes effectively managing their condition. Researchers stress that timely diagnosis and improved glycemic management can prevent serious complications, but major gaps remain, especially in low- and middle-income countries. The findings underscore the urgent need for enhanced screening programs, especially targeting younger populations, and better diabetes management worldwide.
