Epidemiology

In type 1 diabetes (T1D), for which insulin treatment is assumed, the prevalence of severe hypoglycaemia increases with the duration of the disorder. As shown in the graph below, the annual prevalence in people who have had T1D for under 5 years is about 20%, while it exceeds 40% in those who have had the disorder for over 5 years.

In type 2 diabetes (T2D), both duration and medical treatment influence the risk. The annual risk of severe hypoglycaemia is significant for T2D patients on sulfonylureas (SUs) and on insulin, especially if on insulin for over
5 years (> 20% risk).

Non-severe hypoglycaemia, which adults can self-treat, is more common than severe hypoglycaemia, but poses far less risk to health and life.
