Key takeaways

Among adults with Type 1 diabetes using automated insulin delivery systems, about 1 in 4 reported experiencing frequent Level 2 hypoglycemia (low blood sugar)
Many people actively manage their fear of lows by intentionally keeping their blood glucose higher than recommended, which can affect diabetes management
Hypoglycemia-related burdens extend beyond physical symptoms to include psychological and behavioral impacts on daily life
Even with advanced technology like automated insulin delivery, low blood sugar remains a significant concern for many adults with Type 1 diabetes

Understanding the Study

Researchers surveyed 674 adults with Type 1 diabetes to understand how often they experience low blood sugar and how these events affect their lives. Of these participants, 429 were using automated insulin delivery (AID) systems—devices that automatically adjust insulin doses based on glucose readings.

The research was presented at the inaugural Breakthrough T1D Clinical & Research Congress in Philadelphia in October 2026. The goal was to gain a clearer picture of hypoglycemia-related challenges that persist even with modern insulin delivery technology.

What the Research Found

Among adults using automated insulin delivery systems, 24% reported experiencing frequent Level 2 hypoglycemia. Frequent was defined as daily, almost daily, or a few moderate low blood sugar events.

The study also revealed behavioral patterns related to fear of lows. A significant majority of participants strongly agreed that they often intentionally keep their blood glucose higher than recommended to avoid hypoglycemia. This practice—sometimes called 'running high'—reflects how much low blood sugar concerns can influence daily diabetes management decisions.

Why This Matters

Automated insulin delivery systems represent a major advance in Type 1 diabetes care, helping many people reduce the burden of constant glucose monitoring and insulin dosing. However, this research shows that low blood sugar remains a real concern for many users, even with these tools.

Understanding these persistent challenges is important for people with Type 1 diabetes, their families, and healthcare providers. It helps guide conversations about realistic expectations with new technology and identifies areas where additional support or therapies might be helpful.
