About weight gain during pregnancy
Gaining the right amount of weight when you\'re pregnant will help you to lose weight after giving birth, can make your delivery easier and will help make sure your baby is born at a healthy weight. Gaining the right amount of weight during pregnancy also helps prevent early childhood obesity.
-
Not gaining enough weight can cause your baby to be born too small, too early or with birth defects.
-
Gaining too much weight can lead to problems during your pregnancy like high blood pressure, swelling and gestational diabetes.
-
It may cause your baby to be born too big or too early, or increase your chance of requiring a Cesarean section.
-
Women who gain too much weight may also have a harder time starting breastfeeding.
