What is the term for a high level of glucose in the blood?

The term for a high level of glucose in the blood is hyperglycemia. This condition occurs when the blood glucose (sugar) levels rise above the normal range, which can happen for various reasons, such as insufficient insulin production, insulin resistance, or excessive carbohydrate intake. Chronic hyperglycemia is closely associated with diabetes mellitus, leading to its classification as a key indicator of this condition.

In the context of glucose-related terms, hypoglycemia refers to low blood sugar levels, glycosuria indicates the presence of glucose in the urine, and diabetes is a metabolic disorder characterized by high blood sugar levels, but it is not the specific term for elevated blood glucose itself. Thus, hyperglycemia is the precise term used to describe excessive glucose in the bloodstream.
