How much weight should you gain during pregnancy?

According to March of Dimes, if you were underweight before pregnancy, you should aim to gain about 28 to 40 pounds during pregnancy. If you were at a healthy weight before pregnancy, you want to gain about 25 to 35 pounds during pregnancy. If you were overweight during pregnancy, you want to gain about 15 to 25 pounds during pregnancy. If you were obese before pregnancy, you want to gain about 11 to 20 pounds. 

Pregnancies that involve twins have a slightly higher weight gain than a one baby pregnancy. You should aim to gain 37 to 54 pounds if you were at a healthy weight before pregnancy, 31 to 50 pounds if you were overweight, and 25 to 42 if you were obese.

Gaining Too Much Weight During Pregnancy- The Risks

Gaining too much weight during pregnancy has health implications, some of which may include:

  • Increased blood pressure: High blood pressure is unhealthy and in pregnancy can cause issues such as preterm delivery and preeclampsia.

  • Increased risk for gestational diabetes: Elevated blood sugar levels increase the risk of developing gestational diabetes. This may put your baby at risk for premature delivery, jaundice, respiratory disease, future diabetes and obesity. As the mother, gestational diabetes may put you at risk for preeclampsia and c-section delivery if this issue is not addressed immediately.

  • Preeclampsia: A marked rise in blood pressure is one of the first signs of preeclampsia, which, though usually mild, can be very dangerous during pregnancy.

  • Increased risk for complications during birth: Gaining too much weight generally increases the size of your baby. While there is nothing wrong with having a big baby, it can make vaginal delivery very painful and sometimes impossible, leading to a last minute C-section.

  • Increased risk for blood clotting: Pregnant women are about 5 times more likely to develop blood clots than non-pregnant women. Gaining an unhealthy amount of weight during pregnancy can increase this risk.

Where will you gain weight during pregnancy?

Although every pregnancy is different, there are commonalities of where pregnancy weight is carried in the body. According to March of Dimes, for a healthy weight mom-to-be, who gains an average of 30 pounds during pregnancy, the weight is distributed like this:

  • Baby = 7.5 pounds

  • Amniotic fluid = 2 pounds. Amniotic fluid surrounds the baby in the womb.

  • Blood = 4 pounds

  • Body fluids = 4 pounds

  • Breasts = 2 pounds

  • Fat, protein and other nutrients = 7 pounds

  • Placenta = 1.5 pounds. The placenta grows in your uterus (also called womb) and supplies the baby with food and oxygen through the umbilical cord.

  • Uterus = 2 pounds. The uterus is the place inside you where your baby grows
