Maintaining a healthy weight during pregnancy is good for both you and your baby. It is important to gain just the right amount of weight; you don't want it to be too much or too little.
If you gain too little weight, you will be more likely to have your baby too early, or have a low birth weight baby. If you gain too much weight, you may at greater risk for needing a cesarean delivery as well as other pregnancy complications. Too much weight gain can also lead to gestational diabetes, preeclampsia, having a hard time losing the weight after delivery and unsuccessful breastfeeding after your baby is born. Excessive weight gain also increases your risk for chronic diseases such as obesity, heart disease and cancer.
