Which weight gain range is recommended for an obese pre-pregnancy BMI?

• A. 8-15 pounds
• B. 15-25 pounds
• C. 27-40 pounds
• D. 11-20 pounds

Answer: (D)

When someone starts pregnancy with obesity, the amount of weight gained during the pregnancy is kept relatively modest to balance fetal growth with the mother’s health risks. The recommended total gestational weight gain for obesity is about 11 to 20 pounds. Gaining within this range supports the fetus and the necessary physiological changes of pregnancy while reducing the likelihood of complications that come with higher gains, such as larger babies that can complicate delivery, increased risk of cesarean birth, and greater postpartum weight retention. The fetus, placenta, amniotic fluid, increased blood volume, and some fat stores all contribute to pregnancy weight, so a cautious gain helps ensure the pregnancy progresses safely.
