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

For a woman with a normal Body Mass Index (BMI), which ranges from 18.5 to 24.9, the recommended weight gain during pregnancy is between 25 to 35 pounds. This guideline is established by various health organizations, including the Institute of Medicine (IOM), and takes into consideration the health of both the mother and the developing fetus.

Gaining this amount of weight is important as it supports the growth and development of the fetus, provides adequate nutrient reserves for breastfeeding, and maintains the health of the mother throughout pregnancy. Insufficient weight gain can lead to issues such as low birth weight, while excessive weight gain can increase the risk of complications such as gestational diabetes and hypertension.

Thus, the recommendation of 25 to 35 pounds strikes a balance that promotes a healthy pregnancy outcome while also considering maternal health.
