Free Pregnancy Weight Gain Calculator: The Best For Healthy Pregnancy

The Pregnancy Weight Gain Calculator estimates a schedule for healthy weight gain based on guidelines from the Institute of Medicine.

Pregnancy weight gain

Pregnancy is a time of great change for a woman’s body. One of the most noticeable changes is weight gain. This weight gain is necessary to support the growing fetus and to prepare for breastfeeding.

The amount of weight gain that is recommended during pregnancy varies depending on the woman’s pre-pregnancy weight. Underweight women should gain more weight than overweight or obese women.

The following table shows the recommended weight gain during pregnancy by pre-pregnancy BMI:

| Pre-pregnancy BMI | Recommended weight gain

Underweight (BMI < 18.5) | 28-40 pounds |

| Normal weight (BMI 18.5-24.9) | 25-35 pounds | 

| Overweight (BMI 25-29.9) | 15-25 pounds |

| Obese (BMI > 30) | 11-20 pounds |

Most of the weight gain during pregnancy is attributed to the development of the fetus, the uterus, the placenta, amniotic fluid, increased blood volume, and increased fluid volume.

Insufficient or excessive weight gain during pregnancy can lead to complications for the mother and baby. Insufficient weight gain can increase the risk of premature birth and low birth weight. Excessive weight gain can increase the risk of gestational diabetes, preeclampsia, and cesarean section.
