| hyperglycemia | <biochemistry> Too high a level of glucose (sugar) in the blood, a sign that diabetes is out of control. It occurs when the body does not have enough insulin or cannot use the insulin it does have to turn glucose into energy. Hyperglycaemia may be seen in diabetes mellitus, Cushing's disease and Cushing's syndrome. Signs of hyperglycaemia are a great thirst, a dry mouth, and a need to urinate often. For people with insulin-dependent diabetes, hyperglycaemia may lead to diabetic ketoacidosis. Origin: Gr. Glykys = sweet, haima = blood (09 Oct 1997) |

| rebound phenomenon | Generally, any phenomenon in which a variable that has been displaced from its normal state by a disturbing influence temporarily deviates from normal in the opposite direction when the disturbing influence is suddenly removed, before finally stabilizing at its normal state, i.e., a phenomenon involving undershoot; e.g., the subsequent hypoglycaemia that may follow injection of glucose, because the initial hyperglycaemia caused excessive secretion of insulin.
