Secondary hyperaldosteronism (also hyperreninism, or hyperreninemic hyperaldosteronism) is due to overactivity of the renin–angiotensin–aldosterone system (RAAS).. The causes of secondary hyperaldosteronism are accessory renal veins, fibromuscular dysplasia, reninoma, renal tubular acidosis, nutcracker syndrome, ectopic tumors, massive ascites, left ventricular failure, and cor pulmonale.
The Primary Aldosteronism Foundation [36] is a patient-driven initiative committed to creating the paradigm shift that will lead to optimum diagnosis and treatment of primary aldosteronism by raising awareness, fostering research, and providing support to patients and healthcare professionals worldwide.

However, in subjects with glucocorticoid-remediable aldosteronism, ACTH increases the activity of existing aldosterone synthase, resulting in an abnormally high rate of aldosterone synthesis and hyperaldosteronism. [4]
Pseudohyperaldosteronism (also pseudoaldosteronism) is a medical condition which mimics the effects of elevated aldosterone (hyperaldosteronism) by presenting with high blood pressure, low blood potassium levels (hypokalemia), metabolic alkalosis, and low levels of plasma renin activity (PRA).
Hyperaldosteronism is caused by the adrenal gland's overproduction of the hormone aldosterone. The excess production of the adrenal gland, specifically the zona glomerulosa, is the cause of primary hyperaldosteronism. Excessive renin-angiotensin-aldosterone system activation results in secondary hyperaldosteronism. [29]

Secondary hyperaldosteronism, on the other hand, is due to overactivity of the renin–angiotensin system. Conn's syndrome is primary hyperaldosteronism caused by an aldosterone-producing adenoma. Depending on cause and other factors, hyperaldosteronism can be treated by surgery and/or medically, such as by aldosterone antagonists.
Neonatal but improves with age. Adults are usually asymptomatic without treatment. [4] Salt wasting caused by renal unresponsiveness to mineralocorticoids. Patients often present with hyperkalaemic acidosis despite high aldosterone levels.
