The research continues to build that women should adapt to a ‘pre-pregnancy’ lifestyle before getting pregnant. And this doesn’t just mean popping your prenatal vitamins a few months sooner. According to a new study, women at an unhealthy weight at the start of their first pregnancy had more complications in their second pregnancy even when they were at a healthy weight at the start of the second. Obesity is particularly a concern. Overweight women were 156 percent more likely to develop preeclampsia (high blood pressure that can lead to a premature delivery) the second time around and 85 percent more likely to require a cesarean. The best way to prevent this? Get to a healthy weight before you become pregnant by modifying your diet and exercising regularly. And even if you are currently pregnant, it’s never too late to reverse unhealthy habits. What ways do you stay at a healthy weight? Sound off in the comments!
