Aldosterone is a hormone that cause the kidneys to retain salt and water, which increases fluid volume in the body (why women get bloated during PMS) and raises blood pressure. Basically, during premenstrual times, the body is in a period of endothelial dysfunction.

Idiopathic cyclic oedema is a frequent and often unrecognized condition in young women. It is characterized by water and sodium retention with secondary hyperaldosteronism due to capillary hyperpermeability.
