Sign in to saveAlso known as Hyperglycaemia
Hyperglycemia is an unusually high amount of glucose in the blood. It is defined as blood glucose level exceeding 6.9 mmol/L (125 mg/dL) after fasting for 8 hours or 10 mmol/L (180 mg/dL) 2 hours after eating.
Hyperglycemia is a condition where there is too much glucose (sugar) in your blood, typically defined as exceeding 125 mg/dL after fasting or 180 mg/dL two hours after eating. It matters because persistently high blood sugar levels can damage blood vessels and organs over time, which is why monitoring and managing glucose levels is important for overall health.

Hyperglycemia is an unusually high amount of glucose in the blood. It is defined as blood glucose level exceeding 6.9 mmol/L (125 mg/dL) after fasting for 8 hours or 10 mmol/L (180 mg/dL) 2 hours after eating.
==Signs and symptoms== Hyperglycemia may be asymptomatic. Blood glucose levels can rise above normal and cause pathological and functional changes for significant periods without producing any permanent effects or symptoms. During this asymptomatic period, an abnormality in carbohydrate metabolism can occur, which can be tested by measuring plasma glucose.
