• Overproduction of aldosterone by the adrenal glands, which may lead to hypokalemia and/or hypernatremia.

• Overproduction of the hormone aldosterone, which causes the kidneys to retain sodium and water, often leading to high blood pressure.

• The condition that results from prolonged exposure to a supranormal concentration of aldosterone, characterized by hypertension, and may include hypokalemia.

• In hyperaldosteronism, overproduction of aldosterone leads to fluid retention and increased blood pressure, weakness, and, rarely, periods of paralysis. Hyperaldosteronism can be caused by a tumor in the adrenal gland or may be a response to some diseases.

• Aldosterone is a steroid hormone produced exclusively in the zona glomerulosa of the adrenal cortex. It is the major circulating mineralocorticoid in humans.

• Hyperaldosteronism, increased secretion of the hormone aldosterone by the cells of the zona glomerulosa (the outer zone) of the adrenal cortex. The primary actions of aldosterone are to increase retention of salt and water and to increase excretion of potassium by the kidneys and to a lesser extent...
