During pregnancy it is important you drink plenty of water as approximately one cup of water per hour is required for the placenta to replenish amniotic fluid in the womb. This water comes from the intake of the mother and is not made by the body.
Low amniotic fluid can carry risks for your unborn baby which has less fluid to move around in, resulting, in severe cases of dehydration, in compression of fetal organs which can cause birth defects and intrauterine growth restrictions.
Pregnant women also require increased amounts to help with the increased levels of blood and for fetal growth. Each time a cell splits, the daughter cell requires extra fluids as 75% of the cell will be made up of water.
According to recent studies, increasing your water intake can reduce the stresses of morning sickness, puffy eyes, swollen ankles and other signs of edema which are all symptoms of dehydration.
