Women who are overweight or obese when they get pregnant may be at increased risk for miscarriage, stillbirth or infant death. Even modest increases in the mother’s weight was linked to an increased risk of infant death. The danger is greatest for severely obese women, who appear to have about double or triple the risk of losing their baby. Overwhelming data also shows that being overweight or obese increases the risk for type 2 diabetes, gestational diabetes, preeclampsia, high blood pressure and birth defects.
