The Obstetrician series is a virtual forum that provides answers to some frequently asked questions by pregnant women.
What is the required weight gain in pregnancy?
The recommended weight gain in pregnancy is dependent on some variables which include the presence of multiple pregnancies, maternal age & maternal pre-pregnancy weight. These variables can add to the burden of chronic disease for the mother and baby. Excessive weight gain in pregnancy is associated with an increased risk for gestational diabetes, pregnancy-associated hypertension and delivery of large-for-gestational-age (LGA) infants.
In line with the factors stated above, we suggest the following weight gain during pregnancy:
- Underweight women (BMI < 18.5) should gain 28-40 pounds.
- Normal-weight women (BMI, 18.5-24.9) should gain 25-35 pounds.
- Overweight women (BMI, 25-29.9) should gain 15-25 pounds.
- Obese women (BMI, 30 or higher) should gain 11-20 pounds.
*Weight gain should be higher for multiple pregnancies but the ideal amounts are still unknown.
