Pseudo-Cushing Syndrome: Symptoms, Causes, Treatment

Pseudo does not mean symptoms are imagined. It describes cortisol excess without a cortisol-driving tumor; distinguishing causes may require several tests and follow-up.

Weight gain, mood changes and difficult blood-pressure or glucose control are nonspecific. Unexplained bruising, muscle weakness or wide stretch marks warrant closer evaluation.

Severe depression, alcohol use, chronic physical illness or metabolic stress may contribute. All forms of glucocorticoid medicines must also be reviewed because they affect assessment.

Conditions that activate cortisol pathways and conflicting tests increase diagnostic uncertainty. Obesity or depression alone neither proves this diagnosis nor excludes other forms of Cushing syndrome.

A specialist selects urinary cortisol, late-night saliva or suppression testing as appropriate. A random cortisol value or gland scan alone cannot establish the diagnosis.

Care addresses the underlying condition and reassesses cortisol findings. Gland surgery or cortisol-lowering medication is not automatic; long-term steroids must not be stopped abruptly.

Blood-pressure, glucose or bone problems may accompany the underlying condition. Misclassification can lead to unnecessary treatment or delayed recognition of neoplastic Cushing syndrome.

Support treatment of physical or mental illness and review sleep and medicines. Alcohol dependence requires a medically planned approach because abrupt withdrawal may be dangerous.
