What is the recommended total weight gain for a twin pregnancy when the parent has obesity?

• A. 37-54 pounds
• B. 31-50 pounds
• C. 25-30 pounds
• D. 25-42 pounds

Answer: (D)

In twin pregnancies, how much weight you gain depends on your prepregnancy body size, because two babies require more growth support while obesity adds risk if gain is too high. For someone with obesity, the recommended total weight gain is about 25 to 42 pounds. This range aims to provide enough resources for two babies, the placenta, and the expanded body’s needs, while reducing the risks that come with gaining too much weight in obesity, such as pregnancy complications and delivery challenges. Gaining within this range helps balance fetal growth with maternal health, recognizing that weight gain is distributed across fetal and placental tissue, amniotic fluid, increased blood volume, and changes in maternal fat stores.
