Understanding Cortisol – Glucocorticold Receptor Signaling

Explains the cellular and molecular biology of cortisol signaling and cortisol bioavailability. Includes glucocorticoid receptor binding and activity, enzymes such as 11β-HSD, and what these mean for cortisol testing and disease patterns.

What Causes Hypercortisolism?

Covers the main causes of hypercortisolism including pituitary, adrenal, and ectopic neoplasms, as well as physiologic cases such as depression, stress, or alcohol use. Also discusses circadian disruptions and malfunction of feedback loops that prevent proper regulation.

Clinical Features of Hypercortisolism

Reviews the signs and symptoms seen across mild to severe cortisol excess. Discusses how multiple organ systems are affected and how those overlapping conditions should raise suspicion.

Metabolic Dysregulation in Hypercortisolism

Focuses on how cortisol disrupts glucose and lipid balance, which in turn causes insulin resistance and visceral fat gain. Ties chronic elevated cortisol to weight issues, dyslipidemia, and cardiometabolic risk.
