Water needs increase during pregnancy to support fetal development and maternal health
"Pregnant women are advised to consume 300 milliliters more water per day than nonpregnant, nonlactating women," said Rosinger.
The researchers found that as the women progressed through pregnancy, they typically became underhydrated during the second trimester and early part of the third trimester. "We found that as most women remained active in the second trimester, they often experienced an increase in water output. If it wasn't adequately replaced by fluid intake, it could contribute to a greater risk of underhydration," Rosinger said.
The study also sought to discover how hydration levels can affect birth weight and length. The researchers found that during second trimester, women who were inadequately hydrated had lower birth weight z-scores. "Interestingly, we did not see lower birth weights at end of third trimester, indicating catch up growth," Rosinger said.
