How much water should you drink while pregnant?

This is what the expert's answer to the question.

You should drink at least six to eight 8-ounce glasses per day (48 to 64 fluid ounces) plus one 8-ounce cup for each hour of light activity. Juices can contribute to your fluid intake, but keep in mind that they can also provide a lot of extra calories. Caffeinated beverages, such as coffee, colas, and teas don't count as part of your fluid intake because they're diuretics — they make you urinate more so you actually lose water.

Water plays many vital roles in a healthy pregnancy. Think of water as your body's transportation system — it carries nutrients through your blood to the baby. 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.
