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. 

Take a self-assessment test to find out if you're at risk of type 2 diabetes: NHS Choices - Type 2 diabetes self-assessment.

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.
