Nearly 24 million Americans now have diabetes, according to government statistics.
Rising levels of obesity mean the situation is only going to get worse, as the disease is already taking a big financial toll. Research in the Archives of Internal Medicine shows diabetics nearly doubled their spending on drugs for the disease in just six years.
