Being over - or under - weight during a first pregnancy can lead to complications during a second - even if the first birth went fine. That's according to a recent study by scientists at Saint Louis University. What's more, says lead author Maya Tabet, reaching a normal weight by the second pregnancy doesn't seem to help.
"Even if women reach a healthy weight by their second pregnancy, they would be at increased risk of complications just because they started their first pregnancy with an unhealthy weight."
In the United States, about 5 percent of women start a pregnancy underweight, and more than 50 percent are either overweight or obese.
