Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Over time, having too much glucose in your blood can cause health problems, such as heart disease, nerve damage, eye problems, and kidney disease. You can take steps to prevent diabetes or manage it.

There are 425 million people with diabetes in the World. There will be 629 million people with diabetes in the World in 2045. The number of people with diabetes is estimated by taking the IDF diabetes Atlas prevalence estimate and applying it to the number of people aged 20-79 estimated by the United Nations Population Division. The estimate includes both diagnosed and undiagnosed diabetes.
