Weight Gain With Twins

Weight gain during your pregnancy helps your babies get enough nutrients to thrive. But you don't truly need to eat three times as much as usual when you're "eating for three." If you gain too much weight, your babies may deliver early, or become too large. And you're more likely to get high blood pressure, diabetes, or varicose veins. You're also more likely to need a cesarean section if you put on too much weight during pregnancy.

In general, if you are at a healthy weight and carrying twins, you should gain 37 to 54 pounds. If you are overweight, you should gain less. Talk to your doctor.

Call Doctor If:

  • You want to know a good target weight gain for you. Your doctor can help you determine it, based on your BMI (body mass index).
  • You think you are gaining too much weight.
  • You need help determining a good menu plan to gain a healthy amount of weight.
  • You gain weight rapidly. This could be a sign of preeclampsia, pregnancy-related high blood pressure, a serious health issue.


Step-by-Step Care:

  • Shoot for an extra 600 calories extra a day. A glass of skim milk and four fig bars, or a glass of skim millk and half a peanut butter sandwich, are about 600 calories.
  • Try to put on weight slowly and steadily. But don't worry if you have one or two "growth spurts" and then level out.
  • Exercise regularly, with your doctor's OK.
  • Don't diet or try to lose weight while pregnant. It could harm your twins.
