Information for the public
High blood glucose (hyperglycaemia) that is not treated can lead to a serious condition called diabetic ketoacidosis (or DKA for short). It is caused by the build‑up of harmful ketones in the blood. People with type 1 diabetes are at risk of DKA.
You may be advised to test for ketones in your blood or urine as part of sick-day rules.
Your blood ketones may be measured by a healthcare professional if it is thought you might have DKA.
If you have DKA you will need emergency treatment in hospital by a specialist care team. This will include having fluids through a drip.
