Aldosterone is a hormone is produced in the adrenal glands, which are the two triangular shaped glands located above the kidneys.
Aldosterone's main function is the regulation of blood pressure through the retention of sodium. "Where sodium goes, water flows," my physiology professor used to say. By holding on to Na+ (sodium), the body holds in fluid and props up blood pressure.
A low production of Aldosterone causes the body to lose fluid resulting lower blood pressure. This sometimes triggers a craving for salty foods as the body is trying to compensate for dysfunction in the sodium retention mechanism.
