High blood sugar (hyperglycaemia)

Learn about high blood sugar, also known as hyperglycaemia. This condition occurs when there is too much glucose in the blood. Common symptoms include excessive thirst, frequent urination, fatigue, and blurred vision. A blood sugar level above 7 mmol/L when fasting, or higher than 11 mmol/L two hours after eating, is generally considered high. Managing your blood sugar levels can be achieved through a balanced diet, regular physical activity, staying hydrated, and, if necessary, medication as prescribed by your healthcare provider.
