How Education and Lifestyle Changes May Help Pregnant Women with Type 1 Diabetes

Pregnant women with Type 1 diabetes face greater risks of complications compared to those without diabetes. Their babies are also at higher risk for adverse outcomes. Because of these elevated risks, researchers have been studying whether non-medication interventions—such as education, dietary changes, physical activity, and weight management—might help improve outcomes for both mother and baby.

A systematic review published in 2026 analyzed 78 randomized controlled trials testing various approaches with pregnant women who had Type 1, Type 2, or gestational diabetes. The researchers focused on whether education, diet guidance, physical activity programs, and weight management strategies could reduce serious maternal and newborn complications, including maternal death, stillbirth, and neonatal death.

Of the 78 trials identified, 44 provided data on the most critical outcomes and were included in the detailed analysis. It is important to note that most of these studies involved women with gestational diabetes rather than Type 1 diabetes specifically.

When researchers looked at diabetes education programs compared to standard care, they found promising results in one particular area: women who received education had a lower risk of requiring a cesarean delivery. This finding came from 8 studies involving 778 pregnant women with diabetes.

However, it is important to understand that this research does not tell us whether education prevents the most serious complications, such as stillbirth or maternal death. The studies primarily looked at delivery method and other outcomes.

While this systematic review included a large number of studies, most focused on gestational diabetes rather than Type 1 diabetes specifically. This means we have less information about which approaches may work best for pregnant women with Type 1 diabetes in particular.

The researchers carefully evaluated the quality and trustworthiness of the trials they reviewed. The takeaway is that more high-quality research is needed to understand which combinations of education, dietary changes, physical activity, and weight management offer the greatest benefit for women with Type 1 diabetes and their babies.

If you have Type 1 diabetes and are pregnant or planning pregnancy, this research suggests that structured education programs and lifestyle support may be helpful as part of your care plan. However, any decisions about your individual care should be made with your healthcare team, who understand your unique situation.

As more research emerges—especially studies focused on Type 1 diabetes—we will have a better picture of what works best to support healthy pregnancies for women managing Type 1.
