What is healthy weight gain during pregnancy?


How much you should see in weight gain during pregnancy depends on how much you weigh before becoming pregnant. Experts typically advise that if you are:

  • Underweight, you gain 28 to 40 pounds
  • Healthy weight, you gain 25 to 35 pounds
  • Overweight, you gain 15 to 25 pounds
  • Obese, you gain 11 to 20 pounds

Too much weight gain during pregnancy can cause health problems for you and your child. For you, extra weight raises your risk of developing diabetes and high blood pressure while pregnant. Your child could also end up with high blood pressure and other health problems, such as and obesity.

Talk with your healthcare provider to figure out your Body Mass Index (BMI), which will help determine the amount of weight gain that is appropriate for you.
