Weight Gain While Expecting Twins, Triplets Or More

Gaining enough weight during pregnancy is extremely important when you’re carrying multiples. Sufficient weight gain can help stave off preterm birth and helps your babies develop and boost their birth weight. But this weight gain should be slow and steady, and your caloric intake should come from healthful and nutrient-rich foods. Eat five or six times day, and pay attention to the vitamins and minerals you consume.


How much you should gain: If you’re carrying twins and your weight was in the normal range (body mass index of 18.5 to 25) before conception, the American College of Obstetricians and Gynecologists (ACOG) recommends that you gain 35 to 45 pounds during your pregnancy.

When to gain: This means you should be gaining about a pound a week throughout the first half of your pregnancy, and a little more each week throughout the second half.


How much you should gain: If you’re carrying triplets, experts advise you should gain between 58 and 75 pounds before delivery.

When to gain: Try to gain the first 35 pounds within weeks 1 through 20.


How much you should gain: Moms-to-be of quads should be gaining about 70 to 80 pounds during pregnancy, and because quads tend to arrive around 30 weeks, this weight gain should occur rapidly.

When to gain: Get those numbers on the scale to climb 45 pounds by 20 weeks.

If you were underweight before your pregnancy or you lost weight in the first trimester due to morning sickness, you should try to make up that weight gain as early as possible.  If you experience very sudden changes in weight gain or loss, contact your doctor.
