Cushing's Syndrome: 8 Physical Signs Endocrinologists Look for at Your First Visit

Cushing's syndrome occurs when your body is exposed to high levels of the hormone cortisol for a prolonged period. Cortisol helps regulate blood pressure, immune function, metabolism and stress response. When levels go awry—either because of medication or an internal cause—your whole body can show telltale signs. Recognizing these signs early helps endocrinologists confirm a diagnosis and start proper treatment.

Below are eight physical signs your doctor will look for on your first visit. If you notice several of these symptoms in yourself, try Ubie's free AI-powered Cushing's Syndrome symptom checker to better understand your risk and determine if you should seek medical evaluation.

1. "Moon Face" (Facial Rounding)

• Description: Puffiness and rounding of the cheeks, giving the face a "moonlike" appearance.
• What happens: Excess cortisol redistributes fat to your face.
• What to watch for:
  • Noticeably fuller cheeks compared to past photos
  • A general round shape rather than your usual profile
• Why it matters: This is one of the earliest and most recognizable signs.

2. "Buffalo Hump" (Fat Pad on the Upper Back)

• Description: A fatty pad developing at the base of the neck, between the shoulders.
• What happens: Fat tissue accumulates in this area due to cortisol's effect on fat distribution.
• What to watch for:
  • A small to moderately sized hump of tissue
  • Discomfort when leaning back in a chair or wearing heavy necklaces
• Why it matters: Rare in people without cortisol excess, so it raises suspicion quickly.

3. Purple or Pink Striae (Stretch Marks)

• Description: Wide, purplish stretch marks often on the abdomen, thighs, hips or breasts.
• What happens: High cortisol weakens skin fibers, causing rapid tearing when weight is gained.
• What to watch for:
  • Striae wider than 1 centimeter
  • Color ranging from bright purple to pink
  • Stretch marks appearing suddenly, not gradually
• Why it matters: Normal stretch marks are usually thin and silvery; these are thick and pigmented.

4. Central (Truncal) Obesity

• Description: Fat accumulates around the waist, while arms and legs may remain relatively thin.
• What happens: Cortisol shifts fat storage to the abdomen, giving a potbelly look.
• What to watch for:
  • Waist circumference increasing in a short time
  • Thin arms and legs but a bulky torso
  • Clothes fitting tighter around the midsection first
• Why it matters: This pattern is distinct from overall weight gain or typical "apple" body shapes.

5. Proximal Muscle Weakness

• Description: Weakness in muscles closest to the center of the body—shoulders, hips and upper thighs.
• What happens: Cortisol breaks down muscle protein, leading to loss of strength and mass.
• What to watch for:
  • Difficulty climbing stairs or getting out of a low chair
  • Trouble lifting objects overhead
  • Feeling fatigued even after mild exertion
• Why it matters: This muscle pattern (proximal myopathy) is uncommon in other conditions.

6. Thin Skin and Easy Bruising

• Description: Skin appears fragile, thin, and bruises with minimal trauma.
• What happens: Cortisol breaks down collagen and skin tissue.
• What to watch for:
  • Frequent bruises after light bumps
  • Skin that seems translucent, with underlying veins easily seen
  • Slow wound healing
• Why it matters: When paired with other signs, it's a red flag for excess cortisol.

7. High Blood Pressure (Hypertension)

• Description: Elevated blood pressure readings, often resistant to standard treatments.
• What happens: Cortisol increases blood volume and narrows blood vessels.
• What to watch for:
  • Consistent readings above 130/80 mm Hg
  • Dizziness or headaches (though some patients have no symptoms)
  • Blood pressure that doesn't improve with initial lifestyle changes
• Why it matters: Hypertension affects nearly every organ system and increases cardiovascular risk.

8. Changes in Hair Growth and Menstrual Cycle

• Description: Women may experience unwanted hair growth (hirsutism) on the face, chest or back; menstrual irregularities are also common.
• What happens: Cortisol dysregulation can boost androgens (male hormones), disrupting normal hair and menstrual patterns.
• What to watch for in women:
  • New, coarse hair on the face or body
  • Irregular, light or absent menstrual periods
  • Acne breakouts in adulthood
• Why it matters: These changes can significantly affect quality of life and point toward hormonal imbalance.

Putting It All Together

Endocrinologists will look at the overall pattern of these signs—no single feature confirms Cushing's syndrome, but several together raise strong suspicion. They'll also review your medical history, including:

• Use of steroid medications (prednisone, dexamethasone)
• Past episodes of weight gain or blood pressure issues
• Family history of endocrine disorders

If the physical exam and history suggest Cushing's syndrome, your doctor may order:

• Salivary or blood cortisol tests (morning and late-night levels)
• 24-hour urine cortisol measurement
• Low-dose dexamethasone suppression test
• Imaging studies (MRI of the pituitary, CT scan of the adrenal glands)

Why Early Detection Matters

Untreated Cushing's syndrome can lead to:

• Diabetes or impaired glucose tolerance
• Severe hypertension and heart disease
• Bone thinning (osteoporosis) and fractures
• Increased risk of infections
• Mood changes, depression or cognitive difficulties

Catching it early means starting treatment—surgery, radiation, medication or slowing/stopping steroids—so you can reduce long-term complications.

Next Steps: Speak to a Doctor

Physical signs can point toward Cushing's syndrome, but only a healthcare provider can confirm it. If you experience any of these symptoms—especially in combination—please speak to a doctor as soon as possible. Early evaluation and treatment can make a significant difference in your health and quality of life.
