Understanding Pregnancy Weight Gain
Healthy pregnancy weight gain is essential for both maternal health and fetal development. The amount of weight you should gain during pregnancy depends on your pre-pregnancy Body Mass Index (BMI). Our pregnancy weight gain calculator uses guidelines from the Institute of Medicine to provide personalized recommendations.
Proper weight during pregnancy helps ensure your baby grows at a healthy rate and reduces the risk of complications. Gaining too little weight can lead to preterm birth or low birth weight, while gaining too much can increase the risk of gestational diabetes, high blood pressure, and delivery complications.
Pregnancy Weight Gain by BMI Category
Based on your pre-pregnancy BMI, here are the general recommendations for healthy pregnancy weight gain:
- Underweight (BMI less than 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 or greater): 11-20 pounds
For pregnancy with twins, the recommended weight gain is higher: 37-54 pounds for normal weight women, 31-50 pounds for overweight women, and 25-42 pounds for obese women.

A healthy pregnancy weight gain depends on your pre-pregnancy BMI. For women with normal BMI (18.5-24.9), the recommended total weight gain is 25-35 pounds. Underweight women may need to gain 28-40 pounds, while overweight women should aim for 15-25 pounds, and obese women 11-20 pounds.
Proper weight during pregnancy is crucial for fetal development. Adequate weight gain supports the baby’s growth, organ development, and nutrient stores. Insufficient weight gain may lead to low birth weight or preterm birth, while excessive gain can increase the risk of childhood obesity and delivery complications.
In the first trimester, most women gain 1-5 pounds. During the second and third trimesters, the rate of pregnancy weight gain increases. Normal weight women typically gain about 1 pound per week in the second and third trimesters. The pattern may vary based on your pre-pregnancy BMI.
Pregnancy weight distribution includes: baby (7-8 pounds), placenta (1-2 pounds), amniotic fluid (2 pounds), uterine growth (2 pounds), breast tissue (1-2 pounds), blood volume (3-4 pounds), fluids (2-3 pounds), and maternal fat stores (5-9 pounds).
