Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high.
There are two main types of diabetes:
- type 1 diabetes
- type 2 diabetes
Type 2 diabetes is far more common than type 1. In the UK, around 90% of all adults with diabetes have type 2.
For information on type 1 diabetes, visit Type 1 Diabetes (Diabetes website,opens in a new window).
Take a self-assessment test to find out if you're at risk of type 2 diabetes: NHS Choices - Type 2 diabetes self-assessment (opens in a new window)
Many more people have blood sugar levels above the normal range, but not high enough to be diagnosed as having diabetes. This is sometimes known as pre-diabetes. For more information about diabetes and pre-diabetes visit the NHS Choices - Diabetes (opens in a new window).
Diabetes Prevention Services
