Automated Insulin Pumps and Pregnancy: What the Research Shows

Managing Type 1 diabetes during pregnancy is challenging. Pregnancy changes how the body uses insulin, requiring tighter blood sugar control to support both mother and baby. Automated insulin delivery (AID) systems—sometimes called "artificial pancreas" technology—adjust insulin doses automatically based on glucose readings, which can reduce the burden of constant manual management.

A new review examined six randomized controlled trials to understand how well AID systems work during pregnancy. Researchers wanted to know whether these systems help people achieve the specific blood sugar targets that pregnancy requires.

The picture is mixed but hopeful. Some studies showed that people using AID had better blood sugar control compared to those using sensor-augmented pump therapy or standard insulin injections. Other studies found no significant differences between the groups.

One consistent finding: maternal and neonatal outcomes—measures of health for mother and baby—were similar between AID users and those on standard care. Additionally, some pregnant people using AID systems experienced reduced weight gain and other improvements, which is noteworthy since managing weight during pregnancy is part of overall care.

The review examined six different AID systems available in the United States. However, only one—CamAPS FX—is currently FDA-cleared specifically for use during pregnancy with Type 1 diabetes. Unfortunately, CamAPS FX is not yet available in the United States, so pregnant people here using AID are typically on systems approved for general Type 1 diabetes management, not pregnancy.

Among available systems, some are more customizable than others, which matters because pregnancy-specific blood sugar targets are tighter than for non-pregnant adults. Systems with more adjustment options may help healthcare providers dial in better settings for pregnancy goals.

Here's an important reality: no AID system tested so far reliably meets all of the tight blood sugar targets recommended during pregnancy. This doesn't mean AID isn't helpful—it often is—but it means expectations should be realistic.

The good news is that healthcare providers have strategies and workarounds. By adjusting settings carefully and using specific techniques tailored to pregnancy, clinicians can help AID users get closer to those targets. However, this often requires individualized problem-solving rather than a one-size-fits-all approach.

Researchers and device companies are continuing to study how AID systems can better serve pregnant people with Type 1 diabetes. More research is needed to understand how systems can be optimized to meet pregnancy-specific goals more consistently.

If you are pregnant or planning to become pregnant with Type 1 diabetes, these findings suggest that AID systems can be a useful tool when combined with close monitoring and adjustments by your healthcare team—but they work best as part of comprehensive pregnancy care, not as a standalone solution.
