How much weight should I gain during pregnancy?

he American College of Obstetricians and Gynecologists (ACOG) recommends an average weight gain of 25 to 30 pounds during pregnancy. But the amount of weight you should gain depends on your weight before you became pregnant and your height.

According to ACOG:

  • If you were underweight before becoming pregnant, you should gain between 28 and 40 pounds.
  • If you were overweight before becoming pregnant, you should gain between 15 and 25 pounds.

Check with your doctor to find out how much weight gain during pregnancy is healthy for you.

You should gain weight gradually during your pregnancy, with most of the weight gained in the last trimester. Doctors suggest women gain weight at the following rate:

  • 2 to 4 pounds during the first trimester
  • 3 to 4 pounds per month for the second and third trimesters

Recent research shows that women who gain more than the recommended amount during pregnancy and who fail to lose this weight within six months after giving birth are at much higher risk of being obese nearly 10 years later.

Total weight gained during pregnancy includes six to eight pounds for the weight of the baby. The remaining weight consists of fluid, larger breasts, larger uterus, amniotic fluid, and the placenta. Make sure to visit your doctor throughout your pregnancy so he or she can check on your weight gain.
