Weight Gain During Pregnancy: What to Expect
Pregnancy is a time of incredible change, including changes in your weight. For many expectant mothers, understanding how much weight gain in pregnancy is normal can be a source of stress. This guide breaks down what to expect when it comes to weight gain during pregnancy, why your pre-pregnancy weight matters, and tips for maintaining a healthy progression.
How much weight do you typically gain during pregnancy?
The amount of weight you gain during pregnancy depends on several factors, including your pre-pregnancy weight and whether you're carrying twins or multiples. Here’s an overview of average weight gain during pregnancy and what you can expect during each trimester.
Average Weight Gain During Pregnancy
- Normal weight gain during pregnancy: For a single pregnancy, the typical weight gain during pregnancy is 25–35 pounds if you were in the “normal” BMI range before pregnancy.
- Underweight before pregnancy: Your healthcare provider might recommend a gain of 28–40 pounds.
- Overweight or obese before pregnancy: Recommended weight gain ranges from 11–25 pounds depending on your BMI.
Pregnancy Weight Gain Chart by Trimester
- First Trimester: Weight gain is typically minimal, about 1–5 pounds, as the baby is still very small.
- Second Trimester: This is when the most noticeable weight gain occurs—about 1 pound per week.
- Third Trimester: Weight gain slows but remains steady, around 0.5–1 pound per week.
What About Twins or Multiples?
If you’re carrying twins or multiples, the recommended weight gain increases:
- Normal BMI: 37–54 pounds.
- Overweight BMI: 31–50 pounds.
- Obese BMI: 25–42 pounds.
Where does the weight go?
The extra weight gained during pregnancy is distributed across several areas:
- Baby: 7–8 pounds
- Placenta: 1–2 pounds
- Amniotic fluid: 2 pounds
- Uterus: 2–5 pounds

Does your weight before pregnancy matter?
Your pre-pregnancy weight can significantly impact your pregnancy journey, including how much weight you should aim to gain and any potential health concerns.
Underweight Before Pregnancy
Being underweight might increase your risk of having a baby with a low birth weight or preterm delivery. It’s crucial to gain adequate weight to support your baby’s development.
Overweight or Obese Before Pregnancy
Carrying extra weight before pregnancy can raise the risk of complications such as gestational diabetes, high blood pressure, and delivery complications. It may also result in the need for a more tailored weight gain plan, as advised by your healthcare provider.
Talk to Your Doctor
Every pregnancy is unique, and speaking with your healthcare provider can help you determine the right weight gain goals based on your starting weight and overall health.
What happens if you are gaining too much weight or not enough?
Too Much Weight Gain
Gaining more weight than recommended can increase the risk of:
- Gestational diabetes
- High blood pressure
- Difficulty losing weight postpartum
- Larger-than-average babies, which may complicate delivery
If you’re noticing rapid weight gain, consider incorporating low-impact exercise into your routine. Belly Bandit offers maternity support apparel that can make staying active more comfortable.
Not Enough Weight Gain
Insufficient weight gain can lead to:
- Low birth weight for the baby
- Preterm birth
- Developmental delays
If you’re struggling to gain enough weight, focus on nutrient-dense foods and speak to your healthcare provider for personalized advice.
Tips for Maintaining a Healthy Weight Gain
Achieving a healthy weight gain during pregnancy is about balance. Here are some practical tips to help you stay on track:
