What is the recommended weight gain during the second and third trimester?

The recommended weight gain during the second and third trimesters of pregnancy is approximately 1 pound per week. This guidance is based on the need to support the growing fetus, as well as the increased nutritional and energy demands on the mother's body during this critical period.

A weight gain of about 1 pound per week helps ensure that both the mother and the developing baby are receiving adequate nutrition. It is generally suggested that women of average pre-pregnancy weight aim to gain between 25 to 35 pounds throughout their pregnancy, with weight gain occurring more steadily in the later trimesters. This consistent gain contributes to healthy fetal growth and development.

While other weights may seem reasonable, they do not align with the established guidelines for optimal health throughout pregnancy. For instance, gaining more than 1 pound per week may lead to excessive weight gain, which can pose risks to both the mother and baby. Conversely, gaining less may indicate inadequate nutrition, which can hinder fetal development.
