hyperglycemia

This term is a clinical designation used primarily in medical settings to describe a physiological state of excess blood sugar. It carries a neutral, diagnostic tone, though in a patient's history, it indicates a pathological condition that requires intervention to prevent complications like ketoacidosis.

As a mass noun representing a medical condition, it is uncountable. It does not have a plural form and cannot be counted as individual units; instead, clinicians refer to the severity or the presence of the condition rather than multiple instances of it.
