Countries with the highest prevalence of diabetes 2019

In 2019, the Marshall Islands had the highest prevalence of diabetes worldwide, with around 34 percent of the population suffering from the disease. Diabetes mellitus, or simply, diabetes, refers to a group of metabolic disorders that cause high blood sugar levels. Diabetes can be prevented and treated though exercise, maintaining normal body weight, and healthy eating, but is usually managed with insulin injections.


As of 2019, there were over 463 million people worldwide who had diabetes. With such a huge number of people suffering from this disease it is no surprise that spending on diabetes can be very high. It is estimated that the United States alone spent around 295 billion U.S. dollars on diabetes health expenditure in 2019. The countries with the highest spending per patient with diabetes include Switzerland, the United States, and Norway.


Diabetes is among the leading ten causes of death worldwide, accounting for around 1.6 million deaths in 2016. Complications resulting from diabetes include chronic kidney disease, stroke, and cardiovascular disease. Risk of early death is at least doubled among those with diabetes. South East Asia reports the highest number of deaths from diabetes followed by the Western Pacific and Africa.
