What is the recommended weight gain for a normal BMI during pregnancy?

The recommended weight gain for individuals with a normal Body Mass Index (BMI) during pregnancy is between 25 to 35 pounds. This guideline is established based on research that identifies the amount of weight gain necessary to support the health and development of the fetus, as well as the maternal health. Adequate weight gain supports proper fetal growth, placental development, and maternal nutritional needs.

For individuals with a normal BMI, this range is ideal as it helps ensure that the newborn is born with a healthy weight while minimizing risks for both the mother and baby. Insufficient weight gain can lead to complications such as low birth weight, while excessive weight gain can increase the risk for gestational diabetes, hypertension, and complications during labor and delivery.

In this context, other options reflect either insufficient or excessive weight gain for someone with a normal BMI, thereby potentially leading to suboptimal outcomes for mother and baby.
