Will I need specialized care during pregnancy?

If you have a BMI of 30 or higher, your health care provider will closely monitor your pregnancy. He or she might recommend:

• Early testing for gestational diabetes. For women at average risk of gestational diabetes, a screening test called the glucose challenge test is often done between weeks 24 and 28 of pregnancy. If you have a BMI of 30 or higher, your health care provider might recommend the screening test at your first prenatal visit. If your test results are normal, you'll likely repeat the screening test between weeks 24 and 28 of pregnancy. If the results are abnormal, you'll need further testing. Your health care provider can advise you on blood sugar monitoring and control.
• Changes to your fetal ultrasound. A standard fetal ultrasound is typically done between weeks 18 and 20 of pregnancy to evaluate a baby's anatomy. But ultrasound waves don't easily penetrate abdominal fat tissue. This can interfere with the effectiveness of fetal ultrasound. Talk to your health care provider about the best approach for getting an accurate ultrasound.
• Screening for obstructive sleep apnea. This is a potentially serious sleep disorder that causes breathing to repeatedly stop and start during sleep. Women who have obstructive sleep apnea during pregnancy are at increased risk of preeclampsia and other complications. You'll likely be screened at your first prenatal visit. If obstructive sleep apnea is suspected, your health care provider may refer you to a sleep medicine specialist for evaluation and possible treatment.
