PreventionBy Mayo Clinic staff
You might not be able to prevent fetal macrosomia, but you can promote a healthy pregnancy.
- Schedule a preconception appointment. If you're considering pregnancy, talk to your health care provider. He or she might recommend a daily prenatal vitamin. If you're obese, he or she might also refer you to other health care providers — such as a registered dietitian or an obesity specialist — who can help you make changes in your lifestyle and reach a healthy weight before pregnancy.
- Monitor your weight. Gaining a healthy amount of weight — often 25 to 35 pounds (about 11 to 16 kilograms) — supports your baby's growth and development. There's no one-size-fits-all approach to pregnancy weight gain, though. Work with your health care provider to determine what's right for you.
- Manage diabetes. If you had diabetes before pregnancy or you develop gestational diabetes, work with your health care provider to manage the condition. Controlling your blood sugar level is the best way to prevent complications, including fetal macrosomia.
- Include physical activity in your daily routine. Follow your health care provider's recommendations for physical activity.
