When you're overweight

Being overweight before pregnancy increases the risk of various pregnancy complications, such as gestational diabetes, high blood pressure disorders of pregnancy — including preeclampsia — the need for a C-section and premature birth.

Although a certain amount of pregnancy weight gain is recommended for people who are overweight or obese before pregnancy, some research suggests that people who are obese can safely gain less weight than the guidelines recommend. More research is needed.

Work with your health care provider to determine how much weight you should gain during pregnancy. Your health care provider can offer guidance on nutrition and physical activity and strategies to manage your weight throughout pregnancy.
