Abstract:	This chapter reviews physiological changes in volume and osmolality in normal pregnancy, as well as alterations in volume associated with preeclampsia. There is a marked stimulation of the renin–angiotensin–aldosterone (RAA) system and a rise in the plasma concentration during normal pregnancy. In contrast, plasma volume and components of the RAA system decreased preeclampsia. Importantly, activating autoantibodies to the angiotensin II type I receptor (AT1-AA) are present in preeclampsia. There is an evolving literature on the role of inflammatory cells and cytokines in contributing to preeclampsia by leading to production of the AT1-AA, which is discussed in this chapter.
