How is hyperglycemia characterized?

Hyperglycemia is characterized by excessively high blood glucose levels. This condition occurs when the body does not have enough insulin or cannot use insulin effectively, resulting in an accumulation of glucose in the bloodstream.

In a normal physiological state, blood glucose levels are tightly regulated within a specific range. When these levels exceed this range, typically defined as being greater than 140 mg/dL two hours after eating or over 180 mg/dL at any time, this indicates hyperglycemia. It is often associated with diabetes mellitus and can lead to serious complications if left untreated, such as ketoacidosis or hyperglycemic hyperosmolar syndrome.

Understanding hyperglycemia is critical for medical technologists, as it helps in the diagnosis and management of diabetes and related health issues. Monitoring blood glucose levels is a vital part of managing patient health and preventing complications associated with high blood sugar.
