Water plays many vital roles in a healthy pregnancy. Water also helps prevent bladder infections, which are common during pregnancy. If you drink enough water, your urine will stay diluted, reducing your risk of infection.
Water can also stop constipation and help prevent hemorrhoids .
Although it may seem counterintuitive, the more water you drink during pregnancy, the less water your body will retain. Also, drinking enough water prevents dehydration. This is especially important in the third trimester when dehydration can actually cause contractions that can trigger preterm labor. Juices can contribute to your fluid intake, but keep in mind that they can also provide a lot of extra calories. If you just don't like the taste of water, try adding a wedge of lemon or lime, or a little juice for additional flavor.
