How Much Weight Gained During Pregnancy

Pregnancy weight gain: What’s healthy?

Here are some reasons why pregnancy weight gain matters, from fostering your baby’s development to preparing for post-pregnancy weight loss.

Healthy lifestyle choices can support your baby’s health and help you control pregnancy weight gain. Additionally, choosing healthy foods during pregnancy can make it simpler to lose the extra weight after giving birth.

Theres no one-size-fits-all approach to pregnancy weight gain. Your pre-pregnancy weight and body mass index (BMI) are two factors that affect how much weight you should gain during pregnancy. Your health and your babys health also play a role. To decide what is best for you, consult your healthcare provider.

Consider these general guidelines for pregnancy weight gain:
