How do I know if I have Cushing Syndrome?

TL;DR: Cushing Syndrome is characterized by prolonged exposure to high levels of cortisol, often presenting through sudden weight gain in the midsection, a rounded "moon face," and skin thinning. If you suspect you have Cushing Syndrome, the most reliable path to diagnosis involves specialized biochemical testing, such as 24-hour urinary free cortisol or late-night salivary cortisol tests, ordered by an endocrinologist.

What are the early signs and symptoms of Cushing Syndrome?

Recognizing the symptoms of Cushing Syndrome can be challenging because many signs, such as fatigue or weight gain, overlap with common health issues. However, specific patterns often point toward this condition. Early signs that should prompt a clinical investigation include the rapid development of central obesity (fat accumulation around the abdomen and upper back, often called a "buffalo hump"), accompanied by relatively thin arms and legs. Other hallmark clinical features of Cushing Syndrome include easy bruising, purple stretch marks (striae) wider than 1 centimeter, and unexplained high blood pressure or insulin resistance.

How can I perform a self-assessment for Cushing Syndrome?

When monitoring your health, look for clusters of symptoms rather than isolated changes. It is helpful to document these patterns over time to share with a physician. Consider these common markers associated with Cushing Syndrome:

• Physical changes: A round, red, or full face ("moon facies") and fat pads above the collarbones.


• Dermatological indicators: Skin that tears easily, slow wound healing, and dark purple stretch marks on the abdomen, thighs, or breasts.


• Metabolic/Systemic signs: New-onset or difficult-to-control diabetes, persistent high blood pressure, and significant muscle weakness, particularly in the thighs and shoulders.


• Psychological/Cognitive changes: Unexplained anxiety, severe depression, "brain fog," or significant memory lapses.

When should I see a doctor and what tests are used?

If you suspect you have Cushing Syndrome, you should schedule an appointment with your primary care physician to discuss your concerns. Be specific: instead of saying "I feel tired," state, "I am concerned about the rapid physical changes I am experiencing, such as [list specific symptom], and I would like to be screened for hypercortisolism." Your doctor will likely refer you to an endocrinologist. The primary diagnostic tests for Cushing Syndrome include a 24-hour urinary free cortisol test, a late-night salivary cortisol test, or a low-dose dexamethasone suppression test. These tests are designed to measure your body’s cortisol production over a specific period.

Are there red flags that require urgent evaluation?

While Cushing Syndrome is typically a chronic condition, you should seek urgent medical attention if you experience sudden, severe symptoms such as a hypertensive crisis (blood pressure over 180/120 mmHg), signs of a blood clot (e.g., deep vein thrombosis), severe psychiatric distress, or sudden, unexplained muscle paralysis. These require immediate medical intervention regardless of a formal diagnosis.

How do I advocate for myself if my concerns are dismissed?

It is common for patients to feel frustrated if initial tests return normal results, as Cushing Syndrome can be cyclical, meaning hormone levels fluctuate. If you feel your concerns are not being heard, seek a second opinion from an endocrinologist who specializes in pituitary or adrenal disorders.

Next steps

• Maintain a symptom diary documenting the onset and progression of physical changes.


• Request a referral to an endocrinologist, ideally one associated with a major academic medical center.


• Consult the NIH GARD or the Pituitary Society websites for updated patient resources.


• Connect with the Cushing Syndrome community on DiseaseMaps.org to share experiences and find peer support.
