Weight gain during pregnancy
Section titled “Weight gain during pregnancy”Does it really matter how much weight I gain during my pregnancy?
Section titled “Does it really matter how much weight I gain during my pregnancy?”Gaining weight during pregnancy is, of course, inevitable. It isn’t just the baby that contributes to weight gain. Your placenta, increased blood volume, larger breasts, and fat stores to support breastfeeding, also contribute. How much you gain is quite important, as it can affect both you and your baby. There are targets for weight gain that reflect the best outcomes for both of you. Gaining weight within the recommended targets reduces your risk of gestational diabetes, preterm birth, and having a large baby, compared to gaining too much. Your baby will also be less likely to be overweight later in life. Gaining too little weight can also cause problems, with greater risk of low birth weight, preterm birth, and difficulty breastfeeding.
