13-High blood sugar (hyperglycaemia) and how to recognise it

High blood sugar or hyperglycaemia happens when the body has too little insulin or when the body can’t use insulin properly, leaving too much sugar in the blood?

Blood sugar that is too high can be a serious problem if you don’t treat it, so it’s important to begin treatment as soon as you as soon as you discover it.

Part of controlling your diabetes is checking your blood glucose often.

Checking your blood and then treating high blood glucose early will help you avoid problems caused by hyperglycaemia.

If you have any of these symptoms, go and see a doctor quickly:

• Shortness of breath
• Breath that smells like alcohol
• Nausea and vomiting
• Very dry mouth

Remember to tell the doctor or nurse that you have type 1 diabetes and that your blood sugar is very high.
