Pregnancy weight-gain guidelines

There’s no one-size-fits-all approach to pregnancy weight gain. Appropriate weight gain during pregnancy depends on various factors, including your pre-pregnancy weight and body mass index (BMI). Your health and your baby’s health also play a role. Work with your health care provider to determine what’s right for you.
