According to Anna Fleck of Statista, citing data from the NHS, there are two main types of diabetes: Diabetes type 1 is described as a "lifelong condition where the body's immune system attacks and destroys the cells that produce insulin", whiule type 2 occurs when "the body does not produce enough insulin, or the body's cells do not react to insulin properly." Unlike type 2 diabetes, there are no lifestyle changes that you can make to lower your risk of developing type 1.

According to data from the International Diabetes Foundation, more than 1.4 million people are currently living with type 1 diabetes in the United States.

Considering the comparatively smaller population sizes, the United Kingdom, Germany and Canada have particularly high numbers of cases.
