Verified step by step guidance

Understand the role of each hormone in sodium regulation: Glucocorticoids, estrogens, aldosterone, and progesterone.
Glucocorticoids generally increase sodium retention by enhancing the reabsorption of sodium in the kidneys.
Estrogens can also promote sodium retention, often leading to water retention as well.
Aldosterone is a key hormone in the renin-angiotensin-aldosterone system, which increases sodium reabsorption in the kidneys, thus reducing sodium excretion.
Progesterone, on the other hand, acts as a competitive antagonist to aldosterone, reducing its effect and thereby increasing sodium excretion.
