A new study has revealed that diabetes is far more widespread than previously thought. Nearly 350 million adults around the world have the disease, doubling the rate of 30 years ago.
Researchers from Imperial College London and Harvard University analysed data from more than 2.5 million adults across the world. They found that the number of people with Type 2 diabetes, which is linked to obesity and lifestyle, is no longer limited to rich countries.
It is now a global problem, and fast becoming the biggest cost for many health care systems.
