hypercortisolism

This term is a technical medical designation used primarily in clinical settings, endocrinology, and pathology. It describes the physiological state of having too much cortisol, which is the primary stress hormone. While it is the formal name for the condition, clinicians often use the term "Cushing's syndrome" to describe the clinical manifestation of this state.

As a medical condition referring to a specific biochemical state, the word is uncountable. It describes a systemic condition rather than a discrete object or a countable event, meaning it does not take a plural form in standard medical discourse.
