What is the weight gain recommendation during pregnancy for BMI 18-25?

• A. 15-25 pounds
• B. 25-40 pounds
• C. 25-35 pounds
• D. 5-15 pounds

Answer: (C)

Weight gain during pregnancy is guided by pre-pregnancy BMI, with normal BMI signaling a moderate total gain. For someone starting with a normal BMI, the recommended total gain is about 25–35 pounds. This range supports the baby’s growth and placental development while helping the mother maintain health and reduce risks during pregnancy and after birth. In practice, weight tends to come on modestly in the first trimester, then about 0.8–1 pound per week in the remaining trimesters, totaling roughly the 25–35 pound range.

Gaining far less than this can risk fetal growth restrictions, while gaining substantially more than this can increase risks such as gestational diabetes, high blood pressure, cesarean delivery, and larger babies.
