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

The recommended weight gain during pregnancy for a woman of normal weight is appropriately set at 25-35 pounds. This guideline is based on studies that suggest this range optimizes maternal and fetal health outcomes. Adequate weight gain during pregnancy supports fetal growth and development, reducing the risk of complications such as low birth weight or preterm birth.

This range is also designed to ensure that the woman maintains her health, minimizing risks of gestational diabetes, hypertension, and unnecessary cesarean deliveries. The guidelines take into account various factors, including the mother's pre-pregnancy body mass index (BMI), the health of the baby, and the nutritional requirements during pregnancy.

The other options suggest weight gain amounts that are either too low or too high for women of normal pre-pregnancy weight, which could lead to health risks for both the mother and the baby. Weight gain outside the recommended range may not provide adequate nutrients to support fetal development or could lead to excessive fat gain, posing a risk for complications during childbirth and postpartum recovery.
