High blood sugar (hyperglycaemia)

High blood sugar, known as hyperglycaemia, occurs when there is an excess of sugar in your bloodstream. This condition primarily impacts individuals with diabetes and can lead to serious health issues if not managed properly. Those with diabetes may also experience low blood sugar, referred to as hypoglycaemia. To determine if your blood sugar level is elevated, you can undergo a blood sugar (blood glucose) test. Your healthcare team or GP may conduct regular tests, or you might have the option to check your levels at home.
