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 between 25 to 35 pounds. This range is supported by the guidelines from the Institute of Medicine, which take into account the starting weight of the mother and the health of both the mother and the developing fetus.

Gaining this amount of weight is important as it supports the baby's growth and development, as well as the physiological changes that occur in the mother's body. Adequate weight gain helps to ensure that the baby has the necessary nutrients and energy reserves for optimal growth. In addition, it helps to prepare the mother’s body for breastfeeding and postpartum recovery.

The weight gain recommendation varies for women with different BMI ranges; for instance, those who start pregnancy underweight or overweight have different guidelines. It's vital for mothers to aim for this specific range to reduce the risks associated with inadequate or excessive weight gain during pregnancy.
