It can affect people with Type 1 diabetes and type 2 diabetes , as well as pregnant women with gestational diabetes .

It can occasionally affect people who don't have diabetes, but usually only people who are seriously ill, such as those who have recently had a stroke or heart attack , or have a severe infection.

Hyperglycaemia shouldn't be confused with hypoglycaemia , which is when a person's blood sugar level drops too low.
