A 47-year-old female is referred to the endocrinologist for evaluation of her chronically elevated blood pressure, hypokalemia, and hypervolemia. The patient’s hypertension has been refractory to the usual medications such as beta blockers, diuretics, and angiotensin-converting enzyme (ACE) inhibitors. After a full work up including serum and urinary electrolyte levels, aldosterone suppression test, plasma aldosterone to renin ratio, and MRI which revealed an autonomous adenoma, the endocrinologist diagnoses the patient with primary hyper-aldosteronism.

Question:

What is the pathogenesis of primary hyper-aldosteronism?
