For a normal BMI pregnant person with a multiple gestation, what is the recommended weight gain range?

• A. 37 to 54 pounds
• B. 20 to 30 pounds
• C. 10 to 20 pounds
• D. 60 to 80 pounds

Answer: (A)

Twin pregnancies require more maternal weight gain to support two developing fetuses, their placentas, and extra amniotic fluid, while still protecting the mother's health. For someone with a normal pre-pregnancy BMI, the recommended total weight gain is about 37 to 54 pounds. This range reflects balancing adequate fetal growth with maintaining maternal health, and aligns with guidelines that suggest roughly 1 to 1.5 pounds of gain per week after the first trimester. Gains outside this range can increase risks: too little may compromise fetal growth, while too much can raise the risk of hypertensive disorders, diabetes, or delivery complications.
