The world is losing the battle against diabetes as the number of people estimated to be living with the disease soars to a new record of 382 million this year, medical experts said on Thursday. The vast majority have type 2 diabetes – the kind linked to obesity and lack of exercise – and the epidemic is spreading as more people in the developing world adopt Western, urban lifestyles. The latest estimate from the International Diabetes Federation is equivalent to a global prevalence rate of 8.4 percent of the adult population and compares to 371 million cases in 2012. By 2035, the organization predicts the number of cases will have soared by 55 percent to 592 million. Deaths from the disease are now running at 5.1 million a year or one every six seconds. People with diabetes have inadequate blood sugar control, which can lead to a range of dangerous complications, including damage to the eyes, kidneys and heart. If left untreated, it can result in premature death.
