Differential Diagnoses for Uncontrolled Hypertension

Single Most Likely Diagnosis

  • Essential Hypertension: This is the most common cause of uncontrolled hypertension, accounting for about 90-95% of cases. It is a diagnosis of exclusion, made after ruling out secondary causes of hypertension.

Other Likely Diagnoses

  • Medication Non-Adherence: Patients may not be taking their medications as prescribed, leading to uncontrolled hypertension.
  • White Coat Hypertension: Elevated blood pressure readings in a clinical setting, but normal readings at home.
  • Resistant Hypertension: Hypertension that is difficult to control despite the use of multiple antihypertensive medications.
  • Sleep Apnea: A common condition that can contribute to uncontrolled hypertension.
  • Chronic Kidney Disease: Kidney disease can cause hypertension, and uncontrolled hypertension can worsen kidney disease.

Do Not Miss Diagnoses

  • Pheochromocytoma: A rare tumor of the adrenal gland that can cause episodic hypertension and other symptoms. If missed, it can lead to severe cardiovascular complications.
  • Primary Aldosteronism: A condition caused by excess aldosterone production, leading to hypertension and hypokalemia. If untreated, it can lead to cardiovascular disease and stroke.
  • Cushing's Syndrome: A rare endocrine disorder caused by excess cortisol production, leading to hypertension, weight gain, and other symptoms. If missed, it can lead to severe cardiovascular and metabolic complications.
  • Aortic Coarctation: A congenital condition characterized by narrowing of the aortic isthmus, leading to hypertension and other cardiovascular complications. If missed, it can lead to severe cardiovascular disease and death.

Rare Diagnoses

  • Hyperthyroidism: Excess thyroid hormone production can cause hypertension, tachycardia, and other symptoms.
  • Hyperparathyroidism: Excess parathyroid hormone production can cause hypertension, hypercalcemia, and other symptoms.
  • Renal Artery Stenosis: Narrowing of the renal arteries, leading to hypertension and other cardiovascular complications.
  • Glucocorticoid-Remediable Aldosteronism: A rare genetic disorder caused by excess aldosterone production, leading to hypertension and hypokalemia.
