Understanding Fetal Abdominal Circumference (AC) with Gestational Diabetes


If you have gestational diabetes, you'll likely be getting more growth ultrasounds, and with those growth ultrasounds, you may notice or have been told that your baby's abdomen circumference (fetal AC) or tummy size is measuring a bit ahead.


So, you may be wondering, what does this even mean for you and your baby? Do you have to deliver sooner? Can you still have a vaginal delivery? How can you manage this to ensure the healthiest outcome?


We're here to talk about it and help you feel more informed and prepared!

How Blood Sugars Affect Fetal Growth

When you have gestational diabetes, your blood sugar levels may be running higher than normal. This excess glucose can cross the placenta to baby, leading to elevated blood sugar levels in baby.


Your baby’s pancreas responds by producing more insulin, a hormone that helps to lower blood sugar levels but also promotes fat storage and growth.


The extra glucose that crosses the placenta into your baby’s bloodstream is converted into fat, primarily accumulating in the abdominal area. This process is similar to how adults store excess energy, but in your developing baby, it leads to a disproportionately larger abdomen compared to other parts of the body.


That's because elevated insulin levels in your baby do not just help in lowering blood sugars but also act as growth promoters. This effect is particularly noticeable in the abdominal region, contributing to a larger AC.
