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.

It selectively stimulates secretion of aldosterone. The secretion of aldosterone has a diurnal rhythm. Control of aldosterone release from the adrenal cortex: [citation needed] The role of the renin–angiotensin system: Angiotensin is involved in regulating aldosterone and is the core regulator. Angiotensin II acts synergistically with potassium.
Familial hyperaldosteronism is a group of inherited conditions in which the adrenal glands, which are small glands located on top of each kidney, produce too much of the hormone aldosterone. [1] Excess aldosterone causes the kidneys to retain more salt than normal, which in turn increases the body's fluid levels and causes high blood pressure. [1]
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]
Pseudohypoaldosteronism type 1 (PHA1) is characterized by the body's inability to respond adequately to aldosterone, a hormone crucial for regulating electrolyte levels. This condition often manifests with dehydration as the kidneys struggle to retain sufficient salt, leading to symptoms like increased thirst and dry mouth.
Hyponatremia (due to hypoaldosteronism) - Aldosterone is the end product of the renin-angiotensin-aldosterone system that regulates blood pressure via blood pressure surveillance in the Kidney Juxtaglomerular apparatus. Aldosterone normally functions to increase sodium retention (which brings water as well) in exchange for potassium.
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).
