Hyperglycemia
Hyperglycemia refers to high blood glucose levels. It is often associated with diabetes. Glucose levels are a result of the breakdown of food, especially foods high in carbohydrates and sugars. Normally blood glucose levels are controlled by the hormone insulin which is released from the pancreas. The role of insulin is to move glucose from the bloodstream into every cell of the body, including muscle, fat, and liver cells, where the glucose is then used as a source of fuel or energy for metabolic processes.

Hyperglycemia reflects a lack of insulin production or insulin resistance, or both. The result is that the glucose stays in the blood and is not available by the cells as a fuel.
