Healthy Weight Gain in Pregnancy

Posted on September 8, 2016 with 0 comments

Healthy weight gain during pregnancy is important to help your baby grow and get your body ready to breastfeed. Your recommended weight gain depends on your BMI before pregnancy and is determined on an individual basis. A slow, steady weight gain is usually advised during pregnancy.

 

BMI Before Pregnancy BMI Total Weight Gain Rate of Weight Gain for 2nd and 3rd Trimesters
Underweight <18.5 28 – 40 pounds 1 – 1.3 pounds per week
Normal weight 18.5 – 25 25 – 35 pounds 0.8 – 1 pound per week
Overweight 25 – 30 15 – 25 pounds 0.5 – 0.7 pounds per week
Obese >30 11 – 20 pounds 0.4 – 0.6 pounds per week

**If you are pregnant with more than one baby, your weight gain goals may be larger.
