Aldosterone

What is Aldosterone?

Aldosterone is the primary mineralocorticoid hormone produced by the adrenal cortex within the adrenal glands. It plays a crucial role in maintaining the body's electrolyte balance, particularly the regulation of sodium and potassium levels, as well as the control of blood pressure and blood volume.

Function and Regulation of Aldosterone

Aldosterone acts on the kidneys to promote sodium retention and potassium excretion, which directly influences fluid retention and blood pressure. Its production and release are regulated by the renin-angiotensin system, a key hormonal feedback loop that responds to changes in blood pressure, blood volume, and sodium levels.

Clinical Use of the Aldosterone Test

The aldosterone blood test is commonly used in the diagnosis and evaluation of:

Primary aldosteronism (Conn’s syndrome) – a condition where the adrenal glands produce too much aldosterone, often resulting in high blood pressure and low potassium levels

Secondary aldosteronism – typically caused by conditions that overactivate the renin-angiotensin system, such as heart failure or kidney disease

Accurate measurement of aldosterone levels, often alongside renin levels, helps determine the cause of hypertension and guide effective treatment strategies.
