a steroid hormone made by the adrenal cortex (the outer layer of the adrenal gland). it helps control the balance of water and salts in the kidney by keeping sodium in and releasing potassium from the body. too much aldosterone can cause high blood pressure and a build-up of fluid in body tissues. aldosterone is a type of mineralocorticoid hormone.

Aldosterone is a hormone that increases the reabsorption of sodium ions and water and the release (secretion) of potassium ions in the collecting ducts and distal convoluted tubule of the kidneys' functional unit, the nephron. This increases blood volume and, therefore, increases blood pressure. Drugs that interfere with the secretion or action of aldosterone are in use as antihypertensives. One example is spironolactone, which lowers blood pressure by blocking the aldosterone receptor. Aldosterone is part of the renin-angiotensin system.
