The high incidence is attributed to a combination of genetic susceptibility plus adoption of a high-calorie, low-activity lifestyle by India's growing middle class. About 3.8 million people in the United Kingdom have diabetes mellitus, but the charity Diabetes U.K. have made predictions that could become high as 6.2 million by 2035/2036. The NHS spent a daily average of £2.2m (€2.6m; $3.7m) in 2013 on prescriptions for managing diabetes in primary care, and about 10% of the primary care prescribing budget is spent on treating diabetes. Diabetes U.K. have also predicted that the National Health Service could be spending as much as 16.9 billion pounds on diabetes mellitus by 2035, a figure that means the NHS could be spending as much as 17% of its budget on diabetes treatment by 2035. Almost 2.4 million Canadians (6.8%) have been diagnosed with type 1 or type 2 diabetes, based on 2009 cronic disease surveillance data. Prevalence is higher among males (7.2%) than females (6.4%). However these numbers are likely an underestimate, as data obtained from blood samples indicate about 20% of diabetes cases remain undiagnosed. Accounting for the younger age structure in Aboriginal populations, the prevalence of diabetes is 2-3 times higher among First Nations and Métis, compared to the non-Aboriginal population. The prevalence of diagnosed diabetes among Canadians increased by 70% over the decade from 1999 to 2009. The greatest relative increase in prevalence was seen younger adults (35 to 44 years), attributable in part to increasing rates of overweight and obesity. The Public Health Agency of Canada estimates that if current trends in diabetes continue, the number of Canadians living with diabetes will reach 3.7 million by 2019. Diabetes rates in the United States, like across North America and around the world, have been increasing substantially. According to the 2014 Statistics Report done by the CDC it was found that, “Diabetes Mellitus affects an estimated 29.1 million people in the United States and is the 7th leading cause of death. It also increases the chances of mortality, as well as the risk for heart attack, kidney failure, and blindness” While the number of people with diabetes in the US continues to grow, the number of new cases has been declining since 2009, after decades of increases in new cases. In 2014, more than 29 million people had diabetes in the United States, of whom 7 million people remain undiagnosed.
