Pregnancy involves severe challenges to the homeostatic mechanisms of the body, including the control of water balance. Blood plasma volume increases, but pregnant animals react to blood loss as if plasma volume were not expanded. In some species plasma osmolality falls to a new set point, but plasma osmolality still appears accurately regulated. Transient diabetes insipidus or primary polydipsia may occur, suggesting that water regulatory mechanisms become more vulnerable during pregnancy.
