Cushing’s Syndrome

What is Cushing’s Syndrome?

Cushing’s Syndrome is a hormonal disorder caused by excessive cortisol levels in the body. Cortisol is a hormone produced by the adrenal glands that helps regulate metabolism, blood sugar, and immune response. Prolonged exposure to high cortisol levels can lead to serious health problems, including high blood pressure, diabetes, osteoporosis, and increased infection risk.

Causes of Cushing’s Syndrome

• Prolonged use of corticosteroid medications (e.g., prednisone, dexamethasone)
• Pituitary gland tumors (Cushing’s disease) leading to excess ACTH production
• Adrenal gland tumors or hyperplasia (excess cortisol production)
• Ectopic ACTH-secreting tumors (found in lungs, pancreas, or thyroid)
• Genetic predisposition (rare cases)

Symptoms of Cushing’s Syndrome

• Weight gain, especially in the face (moon face) and upper body
• Thin arms and legs with muscle weakness
• Fat deposits around the neck and shoulders (buffalo hump)
• High blood pressure (hypertension)
• Osteoporosis (fragile bones, fractures)
• Purple stretch marks (striae) on the abdomen, thighs, or breasts
• Excessive hair growth (hirsutism) in women
• Mood swings, anxiety, or depression
• Frequent infections and slow wound healing

How is Cushing’s Syndrome Treated?

Treatment depends on the cause:

• Reducing corticosteroid medication (if drug-induced)
• Surgery to remove tumors (pituitary, adrenal, or ectopic)
• Radiation therapy (for inoperable pituitary tumors)
• Medications to lower cortisol levels (ketoconazole, metyrapone, mitotane)

What to Expect During Diagnosis?

• 24-hour urine cortisol test (measures cortisol levels in urine)
• Dexamethasone suppression test (evaluates cortisol response to steroids)
• Salivary cortisol test (measures nighttime cortisol levels)
• Imaging tests (CT/MRI scans) (to detect adrenal or pituitary tumors)

The Importance of Seeking Medical Help

If left untreated, Cushing’s Syndrome can lead to life-threatening complications such as heart disease, diabetes, severe infections, and osteoporosis-related fractures. Early diagnosis and treatment can prevent irreversible damage and improve quality of life. If experiencing persistent symptoms, consult a doctor promptly.
