More than 800 million adults have diabetes globally, many untreated

More than 800 million adults have diabetes worldwide – almost twice as many as previous estimates have suggested – and more than half of those aged over 30 who have the condition are not receiving treatment, according to a new study.

In 2022, there were around 828 million people aged 18 years and older with type 1 and type 2 diabetes worldwide, the study published in The Lancet found. Among adults aged 30 years and older, 445 million, or 59% of them, were not receiving treatment, the authors said.
