What is Endocrine Hypertension — Screening and Differential Diagnosis?

Endocrine hypertension encompasses secondary hypertension forms that develop due to hormonal disorders. An endocrine cause is identified in 5-10% of all hypertensive patients, and treatment can lead to cure or significant improvement.

Primary aldosteronism is the most common cause (5-13% of hypertensive population). It is followed by pheochromocytoma/paraganglioma, Cushing's syndrome, hyperthyroidism, hypothyroidism, hyperparathyroidism, and acromegaly.

Endocrine screening should be considered in young age (<30), resistant hypertension (uncontrolled with ≥3 drugs), hypertensive crisis, hypokalemia, adrenal incidentaloma, or family history of early-onset HT.

Symptoms

Resistant hypertension (below target despite ≥3 antihypertensive drugs)
Paroxysmal hypertensive episodes (pheochromocytoma)
Muscle weakness and hypokalemia (aldosteronism)
Cushingoid appearance (moon face, purple striae, central obesity)
Palpitations and tremor (hyperthyroidism)

Risk Factors

Onset of hypertension at young age (<30 years)
Resistant hypertension (≥3 drugs + diuretic)
Spontaneous or diuretic-related hypokalemia
Adrenal incidentaloma
Family history of early-onset HT or cerebrovascular event
Obstructive sleep apnea

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • If unexplained hypertension is detected at young age (<30)
  • If blood pressure cannot be controlled despite 3 or more antihypertensive drugs
  • In hypertension accompanied by hypokalemia
  • If hypertensive crisis episodes are occurring → URGENT

Treatment Methods

01
Primary aldosteronism: Spironolactone/eplerenone (medical) or adrenalectomy (unilateral adenoma)
02
Pheochromocytoma: Surgery (after alpha-blockade preparation)
03
Cushing's syndrome: Etiology-directed surgery or medical treatment
04
Hyperthyroidism: Antithyroid drugs, RAI, or surgery
05
Acromegaly: Transsphenoidal surgery ± somatostatin analogs
06
Hyperparathyroidism: Parathyroidectomy

Endokrinoloji

Thyroid nodules are very common and the vast majority are benign; however, fine-needle aspiration biopsy may be required based on ultrasound features for malignancy risk assessment.

Management of Graves' Disease

Endokrinoloji

Graves' disease is the most common cause of autoimmune hyperthyroidism, developing with excessive stimulation of the thyroid gland by thyroid-stimulating antibody (TRAb).

Management of Hashimoto's Thyroiditis

Endokrinoloji

Hashimoto's thyroiditis is the most common cause of hypothyroidism, due to autoimmune destruction of the thyroid gland with anti-TPO and anti-thyroglobulin antibodies.

Primary Adrenal Insufficiency (Addison's Disease)

Endokrinoloji

Addison's disease is a potentially life-threatening endocrine disorder presenting with cortisol and aldosterone deficiency due to autoimmune destruction of the adrenal glands.

Cushing Syndrome Diagnostic Workup

Endokrinoloji

Cushing syndrome is an endocrine disorder presenting with central obesity, striae, hypertension, and metabolic disturbances due to chronic glucocorticoid excess; its diagnosis is challenging.

Pheochromocytoma and Paraganglioma

Endokrinoloji

Pheochromocytomas and paragangliomas are rare tumors that secrete excess catecholamines, causing paroxysmal hypertension, headache, sweating, and palpitations.

Primary Hyperaldosteronism (Conn Syndrome)

Endokrinoloji

Primary hyperaldosteronism is a treatable cause of resistant hypertension and hypokalemia caused by excessive aldosterone secretion from the adrenal gland.

Comprehensive Evaluation of Hypopituitarism

Endokrinoloji

Hypopituitarism is a deficiency of pituitary hormone production that leads to multiple endocrine organ failures and requires lifelong hormone replacement.
