What is the recommended weight gain for a normal BMI pregnant woman?

The recommended weight gain for a pregnant woman with a normal Body Mass Index (BMI) typically falls within the range of 25 to 35 pounds. This recommendation is based on guidelines from the Institute of Medicine (IOM) and reflects the additional caloric and nutritional needs during pregnancy to support the developing fetus while also taking into account the mother's health. Weight gain is essential not only for the growth of the baby but also for the body to prepare for the demands of childbirth and lactation.

Gaining within this specified range helps to reduce the risks of complications such as preterm birth, gestational diabetes, and hypertension, while also preventing excessive weight retention after childbirth. The 25 to 35-pound range is optimal for women who begin their pregnancy at a healthy weight, ensuring an adequate amount of energy is available for fetal growth and development.

More specific guidelines may adjust this range based on the woman's total weight and general health, but the average recommendation for those with a normal BMI remains 25 to 35 pounds.
