Automated Insulin Delivery During Pregnancy: What Women With Type 1 Diabetes Need to Know

For women with type 1 diabetes, managing blood sugar during pregnancy—and especially around the time of delivery—is critically important. Uncontrolled glucose levels can increase the risk of low blood sugar in newborns immediately after birth, a condition called neonatal hypoglycemia. After delivery, insulin requirements often drop quickly, which means mothers are at higher risk for their own hypoglycemic episodes if insulin doses aren't adjusted promptly.

These risks make the peripartum period—the time just before, during, and immediately after delivery—one of the most carefully managed times for women with type 1 diabetes.

Historically, some women with type 1 diabetes were asked to switch away from their personal insulin delivery methods during labor and delivery. Options included going back to manual insulin injections or using intravenous (IV) insulin infusions administered by hospital staff.

But new research is showing that automated insulin delivery systems—the same ones many women use at home—may be a safe and effective choice during the peripartum period. These systems include insulin pumps that adjust insulin delivery based on continuous glucose monitor readings.

A review published in the Journal of Diabetes and Its Complications examined clinical guidelines, recent research, and data from specialized diabetes clinics to evaluate whether AID systems work well during pregnancy, labor, and postpartum recovery. The research supports continuing automated insulin delivery systems during this critical time.

However, this recommendation comes with an important condition: it should only happen if the patient wants to continue using AID and if several basic safety criteria are met. This means your healthcare team needs to assess your individual situation and make sure you have the support and monitoring needed to use AID safely during this period.

If you're a woman with type 1 diabetes planning pregnancy or currently pregnant, this research suggests a conversation worth having with your obstetrics and endocrinology teams. Rather than automatically assuming you'll need to switch insulin delivery methods during labor and delivery, you may be able to continue using a system you're already familiar with—which can help maintain your independence and reduce the stress of learning a new insulin delivery method during a vulnerable time.

The key is planning ahead. Work with your care team to determine if continuing your AID system is safe for your specific situation, understand what monitoring and adjustments will be needed during labor and delivery, and feel confident in your plan before you go into labor.
