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.
Rather, both renin and aldosterone are measured, and a resultant aldosterone-to-renin ratio (ARR) is used for case detection. [20] [21] A high aldosterone-to-renin ratio suggests the presence of primary hyperaldosteronism. The diagnosis is made by performing a saline suppression test, ambulatory salt loading test, or fludrocortisone suppression ...
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.
Hypoaldosteronism is a clinical condition marked by either an aldosterone deficiency or impaired tissue-level action of the hormone. Angiotensin I to Angiotensin II conversion, adrenal aldosterone synthesis and secretion, abnormal target tissue response to aldosterone, and renal renin production and secretion are all potential causes of the ...
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 ...

Functional adrenocortical adenomas demonstrate symptoms consistent with mixed endocrine syndromes. In most reported cases of adrenocortical adenoma, patients have presented with one or multiple endocrine syndromes such as hyperaldosteronism / Conn's Syndrome , [ 3 ] hypercortisolism / Cushing's syndrome , [ 4 ] hyperandrogenism / feminization ...
