Hyperglycemia or Hyperglycæmia, or high blood sugar, is a condition in which an excessive amount of glucose circulates in the blood plasma. This is generally a glucose level higher than (200 mg/dl). Reference ranges for blood tests are 11.1 mmol/l, but symptoms may not start to become noticeable until even higher values such as 250–300 mg/dl or 15–20 mmol/l. A subject with a consistent range above 126 mg/dl or 7 mmol/l is generally held to have ...

Hyperglycemia or Hyperglycæmia, or high blood sugar, is a condition in which an excessive amount of glucose circulates in the blood plasma. This is generally a glucose level higher than (200 mg/dl). Reference ranges for blood tests are 11.1 mmol/l, but symptoms may not start to become noticeable until even higher values such as 250–300 mg/dl or 15–20 mmol/l. A subject with a consistent range above 126 mg/dl or 7 mmol/l is generally held to have hyperglycemia. Chronic levels exceeding 7 mmol/l (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.
It is critical for patients who monitor glucose levels at home to be aware of which units of measurement their testing kit uses. Glucose levels are measured in either:
Scientific journals are moving towards using mmol/l; some journals now use mmol/l as the primary unit but quote mg/dl in parentheses.
Glucose levels vary before and after meals,...
