Hyperglycemia

Hyperglycemia, hyperglycaemia, or high blood sugar is a condition in which an excessive amount of glucose circulates in the blood plasma. This is generally a blood glucose level of 10+ mmol/L (180 mg/dl), but symptoms may not start to become noticeable until later numbers like 15-20+ mmol/L (270-360 mg/dl)or 15.2-32.6 mmol/L. However, chronic levels exceeding 125 mg/dl can produce organ damage.

The origin of the term is Greek: hyper-, meaning excessive; -glyc-, meaning sweet; and -emia, meaning "of the blood".
