Secondary Causes of Hypertension

Although not that common, consider the following (with accompanying history and/or physical examination findings) in patients with hypertension:

  • Renovascular hypertension (renal artery stenosis)-abdominal bruits, older patients
  • Pheochromocytoma-episodic flushing, htn, headache, new onset htn in younger patient
  • Cushing's disease-abdominal striae (not very specific in Baltimore), new onset hyperglycemia, classic electrolyte abnormality: hypokalemic metabolic alkalosis
  • Primary Aldosteronism-new onset htn and hypokalemia
  • Hyperparathyroidism-htn and hypercalcemia
  • Aortic coarctation-younger patients (even young adulthood), unequal upper and lower extremity blood pressures
  • Sleep apnea-typically obese patients (but not necessarily), excessive snoring, day time sleepiness (again, not specific)
  • Thyroid disease (hypo or hyper)-signs and symptoms of thyroid disease

Although most of the time the patient will end up having essential hypertension, these entities should at the very least be considered.
