How much weight gain is typically recommended for a woman of average weight during pregnancy?

The recommendation for weight gain during pregnancy for a woman of average weight (generally considered as having a Body Mass Index, or BMI, between 18.5 and 24.9) is typically between 25 to 35 pounds. This range supports the health of both the mother and the developing baby, providing necessary nutrients and facilitating fetal growth.

Weight gain during pregnancy is essential as it contributes to the healthy development of the fetus, supports increased maternal blood volume, and prepares the body for breastfeeding. The guidelines consider that gaining too little weight may pose risks for the baby, such as low birth weight and developmental issues, while excessive weight gain can increase the risk of complications such as gestational diabetes and hypertension.

The other options suggest weight gain that is either below or above the recommended range. Gaining less than 25 pounds may not meet the nutritional needs for optimal fetal development, while gains over 35 pounds could lead to complications for the mother and baby, affecting long-term health post-delivery. Hence, the range of 25 to 35 pounds is established based on evidence to promote healthy pregnancy outcomes.
