Health condition
Pseudo-Cushing's states
Pseudo-Cushing's states are conditions - alcohol excess, depression, obesity, poorly controlled diabetes - that mildly raise cortisol and mimic Cushing's syndrome on tests without a cortisol-producing tumour.

Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
Alcohol dependence, severe depression, obesity and uncontrolled diabetes can all push cortisol tests into the abnormal range
-
The physical signs that best point to true Cushing's are thin skin, easy bruising, purple stretch marks and proximal muscle weakness
-
Distinguishing tests include repeated late-night salivary cortisol and the dexamethasone-CRH test in specialist hands
-
Treating the underlying driver - for example alcohol - normalises the cortisol
-
Specialist: a consultant endocrinologist; the distinction matters because pituitary surgery would be the wrong treatment
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
The stress axis is not a simple on-off switch: chronic alcohol excess, major depression and severe obesity genuinely activate it, producing modestly raised urinary and salivary cortisol and blunted dexamethasone suppression. The result looks biochemically like mild Cushing's syndrome. What is usually missing are the catabolic signs - paper-thin skin, spontaneous bruising, wide purple striae and true proximal weakness - which reflect prolonged, severe cortisol excess.
Diagnosis and treatment routes
Separating the two takes an experienced endocrinologist: the pattern and degree of abnormality, repeated late-night salivary cortisols, and sometimes combined dexamethasone-CRH testing or a period of abstinence from alcohol before retesting. Getting it right prevents both missed Cushing's and unnecessary pituitary investigation. Most people start with their GP; NHS endocrinology waits are commonly 20-45+ weeks, while a private consultation is typically available within about two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant endocrinologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
A quiet reminder
This guide is for information, not medical advice.
Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any of the emergency symptoms described above.
Frequently asked
Common questions about Pseudo-Cushing's states.
Quick, plain-English answers to what people ask us most.
-
What are pseudo-Cushing's states?
Pseudo-Cushing's states are conditions that cause symptoms and test results resembling Cushing's syndrome (excess cortisol), such as weight gain and mood changes, without an underlying cortisol-producing tumour being present.
-
What causes pseudo-Cushing's states?
Chronic alcohol use, severe depression, significant obesity, and poorly controlled diabetes are among the recognised causes, each of which can disrupt the body's normal cortisol regulation temporarily.
-
What are the symptoms?
Symptoms can overlap significantly with true Cushing's syndrome, including weight gain, particularly around the abdomen, mood changes, and sometimes mild skin changes, though typically less pronounced than in true Cushing's syndrome.
-
How is pseudo-Cushing's distinguished from true Cushing's syndrome?
This can be challenging, as basic cortisol tests can overlap between the two conditions; specific dynamic testing and careful clinical assessment by an endocrinologist, sometimes with a period of monitoring, help distinguish between them.
-
Is pseudo-Cushing's dangerous?
It's not dangerous in the same way as true Cushing's syndrome, since there's no underlying tumour, but the conditions causing pseudo-Cushing's, such as significant alcohol use or depression, need their own appropriate treatment.
-
How is pseudo-Cushing's treated?
Treatment focuses on addressing the underlying cause, such as reducing alcohol intake, treating depression, or managing obesity and diabetes, after which cortisol-related symptoms and test abnormalities typically resolve.
-
How is pseudo-Cushing's diagnosed?
Diagnosis involves a combination of specific cortisol testing, careful assessment of the clinical picture and potential contributing factors, and sometimes specialist dynamic testing to differentiate from true Cushing's syndrome.
-
How long does it take to resolve?
Once the underlying cause is addressed, such as stopping alcohol use or treating depression, cortisol-related abnormalities typically normalise over weeks to a few months.
-
Pseudo-Cushing's vs true Cushing's syndrome — what's the difference?
True Cushing's syndrome is caused by an actual tumour producing excess cortisol (or excess steroid medication use), needing specific tumour-directed treatment, while pseudo-Cushing's is a functional state driven by another underlying condition, resolving once that condition is treated.
-
When should I see a specialist, and how quickly can I be seen privately?
See an endocrinologist if you have symptoms suggestive of excess cortisol needing clarification. Private specialist assessment is typically available within about two weeks, faster than standard NHS referral pathways.
