Ask the average woman how much weight she should gain during pregnancy, and she'll probably respond 25-35 pounds. This Institute of Medicine guideline has been the practice for nearly 20 years. However, this recommendation is for normal weight women (i.e., body mass index [BMI] 18.5-24.9). The IOM also recommends that overweight and obese women limit their gestational weight gain according to their prepregnancy BMI.
A recent study, however, shows that many overweight and obese women are not limiting their weight gain during pregnancy, and this can have serious consequences for both the mother and newborn. In their study of over 7,500 women, researchers found that 64.3% of overweight and 52.9% of obese women gained more weight during pregnancy than recommended by the IOM for their BMI. Further, overweight and obese women were more likely to deliver by C-section and give birth to infants who were large for gestational age, with associated complications including the infant’s anterior shoulder becoming stuck above the pubic bones during delivery, birth canal lacerations, and fetal hypoglycemia (low blood sugar). Overweight/obese women also were less likely to initiate or continue breastfeeding beyond 10 weeks.
So if you are planning to become pregnant in the next year, take a look at your BMI. If you're above 25, talk to your doctor about steps to lose weight. Further, once you become pregnant, keep an eye on your diet and the scale. Pregnant women need only an additional 300 calories per day. By watching your weight before and during pregnancy, you'll not only improve your own health, but you'll also improve the health of your baby.
