Yes. Weight gain in pregnancy is common and expected. Your body is nourishing a whole other being, so you need to make sure you are eating an extra-healthy diet full of healthy fats and other nutrients. Most women gain 22 to 26 pounds over the course of their pregnancy. Too little weight gain can negatively impact your unborn child; too much weight gain can lead to increased complications for you and the baby, such as gestational diabetes, high blood pressure problems, and increased need for a C-section. Check with your healthcare provider throughout your pregnancy to make sure you are maintaining a healthy weight for you and your baby.
