Cushing’s Syndrome in Dubai Unique Endocrine Care for a Complex Hormonal Disorder
Comprehensive diagnosis and personalised treatment for cortisol excess, weight gain, fatigue, diabetes, hypertension, muscle weakness, and mood changes. Dr. Ali Aldibbiat provides expert endocrine evaluation to confirm cortisol excess, identify the source, and guide long-term specialist management.
What Is Cushing's Syndrome?
Cushing's syndrome is caused by prolonged exposure to excess cortisol. Because early symptoms can resemble common metabolic or lifestyle problems, confirming true cortisol excess is the essential first step.
Prolonged exposure to excess cortisol
Cortisol helps regulate blood pressure, blood sugar, immune function, and the stress response. In Cushing's syndrome, cortisol remains abnormally elevated over time.
Tumour-driven hormone production or long-term external steroid use can disrupt this feedback system and maintain cortisol exposure beyond the body's normal requirements.
What Causes Cushing's Syndrome? Four Distinct Pathways
Distinguishing the source of cortisol excess determines the treatment pathway. External steroid exposure, pituitary ACTH production, adrenal cortisol production, and ectopic ACTH secretion require different management strategies.
Exogenous Cushing's
Long-term oral, inhaled, or injected corticosteroid treatment can produce Cushingoid features while suppressing the body's own cortisol production. Management requires specialist-supervised gradual steroid reduction rather than abrupt withdrawal.
Cushing's Disease
A benign pituitary adenoma produces excess ACTH, driving both adrenal glands to produce excess cortisol. The source content identifies this as approximately 70% of endogenous Cushing's syndrome.
Adrenal Cushing's Syndrome
An adrenal adenoma, or more rarely adrenal carcinoma, produces cortisol directly. ACTH becomes suppressed, helping distinguish an adrenal source after biochemical cortisol excess has been confirmed.
Ectopic ACTH Syndrome
A tumour outside the pituitary produces ACTH autonomously. The source document notes lung carcinoid and small-cell lung cancer among the possible sources and describes presentation as potentially rapid and severe.
Central Weight Gain and Moon Face
Weight may concentrate around the abdomen, face, and upper back, while the arms and legs become relatively thinner.
Purple Striae and Fragile Skin
Wide purple or red stretch marks, easy bruising, thinning skin, and poor wound healing reflect cortisol's effects on connective tissue.
Muscle Weakness
Proximal weakness can make standing from a chair or climbing stairs noticeably more difficult.
High Blood Pressure and Diabetes
Cortisol excess can raise blood pressure and impair insulin sensitivity, causing new or increasingly difficult metabolic disease.
Mood and Cognitive Changes
Depression, anxiety, irritability, and difficulty concentrating may appear before some of the more obvious physical features.
Menstrual Changes and Reduced Libido
Excess cortisol can suppress reproductive hormone signalling, contributing to menstrual disturbance in women and reduced libido or erectile dysfunction in men.
When Should You See a Doctor for Cushing's Syndrome?
Specialist assessment becomes particularly important when several characteristic features appear together or symptoms progress rapidly.
Central weight gain, purple striae, and muscle weakness developing together.
New diabetes or difficult-to-control hypertension alongside other Cushing's features.
Long-term steroid treatment followed by development of Cushingoid features.
Rapid development of severe symptoms over weeks rather than months.
Unexplained fractures or bone pain together with other signs of cortisol excess.
Mood symptoms that persist despite standard treatment and occur with physical Cushing's features.
When only one or two milder features are present, the source content proposes late-night salivary cortisol or 24-hour urinary free cortisol as possible initial screening approaches, followed by specialist assessment when results are abnormal or symptoms progress.
Cushing's Syndrome Treatment in Dubai
Treatment is cause-specific. Pituitary, adrenal, ectopic, and medication-induced Cushing's syndrome do not follow the same therapeutic pathway.
Control cortisol. Treat the source. Monitor recovery.
Surgery is first-line for appropriate pituitary and adrenal causes. Cortisol-lowering medication can be used before surgery, for residual disease, recurrence, or when surgery is not immediately possible.
Transsphenoidal Pituitary Surgery
First-line treatment for Cushing's disease. The source document reports remission in approximately 70–90% of cases when performed by an experienced pituitary surgeon.
Steroidogenesis Inhibitors
Ketoconazole, metyrapone, and osilodrostat are described as options to reduce cortisol production before surgery, treat residual or recurrent disease, or provide control when surgery is not immediately possible.
Adrenalectomy
Surgical removal of the cortisol-producing adrenal lesion is the cause-directed treatment for adrenal Cushing's syndrome. Temporary hydrocortisone replacement may be required while the remaining adrenal gland recovers.
Managing Exogenous Cushing's Syndrome
Steroid medication is reduced gradually under specialist supervision so suppressed adrenal function can recover while avoiding adrenal insufficiency.
Long-Term Surveillance
Follow-up may include cortisol testing for recurrence, bone-density assessment, and continued management of hypertension, diabetes, and dyslipidemia that may persist after cortisol normalises.
The diagnostic results determine which treatment pathway is appropriate and what monitoring is required before and after treatment.

Cortisol excess should be confirmed biochemically before localisation imaging. ACTH is then used to determine whether the source is pituitary, ectopic, or adrenal.
Imaging second.
Initial Screening Tests
The source pathway uses 24-hour urinary free cortisol, late-night salivary cortisol, and the overnight 1 mg dexamethasone suppression test. It specifies that at least two tests should be abnormal for diagnosis.
ACTH Measurement
Suppressed ACTH with high cortisol points toward an adrenal source. Elevated or inappropriately normal ACTH points toward a pituitary or ectopic ACTH-dependent source.
Pituitary MRI or Adrenal CT
Pituitary MRI is used for ACTH-dependent disease, while adrenal CT is used after biochemical evidence suggests an ACTH-independent adrenal source.
Inferior Petrosal Sinus Sampling
When pituitary MRI does not provide a clear answer in ACTH-dependent Cushing's syndrome, specialised venous ACTH sampling can help distinguish a pituitary source from an ectopic source.

Cushing's syndrome results from prolonged exposure to excess cortisol. Typical features include central weight gain, muscle wasting, high blood pressure, diabetes, and a rounded face. Long-term steroid medication is the most common overall cause; among endogenous causes, pituitary ACTH-producing disease is the most frequent.
Causes include long-term steroid medication, a pituitary ACTH-secreting adenoma, an adrenal cortisol-producing lesion, or more rarely an ectopic ACTH-producing tumour. Biochemical cortisol confirmation should precede imaging.
Central weight gain with thinner limbs, rounded facial appearance, purple stretch marks, proximal muscle weakness, hypertension, diabetes, mood changes, menstrual disturbance, and reduced libido can form the characteristic pattern.
Many cases can be treated definitively when the source is removable. The source document reports 70–90% remission after transsphenoidal pituitary surgery for Cushing's disease and identifies adrenalectomy as definitive treatment for suitable adrenal disease. Long-term follow-up remains important.
Yes. Persistent cortisol excess can substantially increase cardiovascular, bone, infectious, and psychiatric complications. Early diagnosis and source-directed treatment are therefore important.
A consultant endocrinologist is the appropriate specialist for evaluation of suspected Cushing's syndrome. Dr. Ali Aldibbiat provides the structured pathway from cortisol screening and ACTH testing through localisation and surgical coordination when required.
Your Next Step Starts With a Clear Diagnosis.
Cushing's syndrome requires more than a single cortisol result. Begin with a structured endocrine assessment designed to confirm cortisol excess, identify its source, and define the correct treatment pathway.
