What is effect of estrogen and progesterone on body water content during pregnancy?

================

Answer

Estrogen and progesterone are increased during pregnancy increasing total body water through acting on renal tubules. In high levels during pregnancy, they cause salt & water retention. Progesterone acts mainly on distal tubules of the kidney and to be noted at its normal level, it causes natriuresis (sodium loss in urine).
