Aldosterone

Aldosterone is an important steroid hormone.^[1][2] It keeps sodium in the kidney, salivary glands, sweat glands, and colon.

It plays a central role in the homeostatic regulation of blood pressure, plasma sodium (Na⁺), and potassium (K⁺) levels. Indirectly, it influences water retention or loss, blood pressure and blood volume.
