A new study by the Centers for Disease Control and Prevention, released on Thursday, says nearly half of expecting mothers across the US gain too much weight during their pregnancy. The study, which involved more than three million pregnant women in 46 states, during 2012 and 2013, found that 47 percent of pregnant women gained more than the recommended amount of weight, while 21 percent gained too little.
For a normal pregnancy weight gain, the report recommends women consume an additional 340 to 450 calories per day, but only during the second and third trimesters. Women who were already overweight or obese before becoming pregnant were most at risk of putting on excessive weight. Experts say that putting on too much weight could cause harm to the mom as well as the baby, including future maternal and childhood obesity. Women who gain too little weight, on the other hand, might put their babies at risk of low birthweight, potentially increasing their risks of diabetes, heart disease, high blood pressure and obesity later in life.
