When Aldosterone Release Is Inhibited?

Aldosterone secretion may be inhibited by potassium depletion

potassium depletion
Hypokalemia is associated with increased risk of arrhythmia in patients with cardiovascular disease, as well as increased all-cause mortality, cardiovascular mortality and heart failure mortality by up to 10-fold. Long-term potassium homeostasis depends on renal potassium excretion.

atrial natriuretic factor
Atrial natriuretic factor (ANF) is a 28 amino acid polypeptide hormone secreted mainly by the heart atria in response to atrial stretch. ANF acts on the kidney to increase sodium excretion and GFR, to antagonize renal vasoconstriction, and to inhibit renin secretion.

What happens when aldosterone is inhibited?

It's also possible to have low levels of aldosterone. Primary adrenal insufficiency, a disease that causes a general loss of adrenal function, can be a cause. Patients with primary adrenal insufficiency causing low levels of aldosterone may experience low blood pressure, increased potassium levels, and lethargy.

What happens if aldosterone secretion is blocked?

By blocking the effects of aldosterone, aldosterone receptor antagonists block the reabsorption of sodium, which encourages water loss. Consequently, this leads to a decrease in blood pressure and a reduction in fluid around the heart.
