Plus sized and pregnant women face greater risks of certain complications like gestational diabetes and preeclampsia. They also have higher rates of neural tube defects in babies, which affect brain and spinal cord development. However, most plus sized women have healthy pregnancies if they eat well, exercise, and monitor their weight gain. The risks can be reduced further by taking prenatal vitamins with extra folic acid before and during pregnancy. Close monitoring and managing weight and health conditions helps ensure a healthy pregnancy and baby.
