How does the body store sodium?


The body regulates sodium storage and excretion through a pattern of hormonal control. Regardless of the amount of salt consumed, sodium is stored and released in regular weekly and monthly patterns. This adaptation to salt intake is regulated by hormones such as aldosterone, which controls sodium excretion from the kidneys, and glucocorticoids from the adrenal glands. These hormones adjust the body's sodium and water balance, leading to constant salt retention and urine fluid excretion 1. Additionally, the body can store sodium in various organs, and this is regulated homeostatically, meaning the body's craving for salt can indicate a need for more sodium, especially in conditions where there is excessive sweating or in very hot or cold environments 2.
