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

The recommended weight gain during pregnancy for a woman with a normal Body Mass Index (BMI) is typically between 25 to 35 pounds. This range is established based on the need to support fetal growth, prepare the mother’s body for breastfeeding, and provide nutritional reserves necessary during pregnancy.

A weight gain within this range helps reduce the risks associated with both underweight and overweight conditions during pregnancy, such as preterm birth, developmental issues, and gestational diabetes. This recommendation takes into account the average weight of the baby, the placenta, increased blood volume, and additional amniotic fluid, as well as changes in breast and uterine tissue.

Weight gain outside this range can indicate potential health risks or nutrient deficiencies, so understanding this guideline is crucial for promoting the health of both the mother and the child throughout the pregnancy.
