Understanding why some people with type 1 diabetes don’t notice low blood sugar
Official title: Elucidating the heterogeneity of impaired awareness of hypoglycaemia in type 1 diabetes
Funded at University of Leicester · NIH-11324594 · Data updated 2026-11-12
Researchers are studying why some people with type 1 diabetes don’t recognize hypoglycemia and how modern insulin systems might help restore that awareness.

Who could benefit from this research
✓Could help
Adults with type 1 diabetes who have impaired awareness of hypoglycemia and are using or eligible for hybrid closed loop insulin delivery.
✕Less likely to help
People without impaired awareness or without access to relevant technology may not benefit.
What this research studies
This project will enroll individuals with type 1 diabetes and impaired awareness of hypoglycemia to study their physiological responses during controlled low-blood-sugar conditions. It will compare traditional management with hybrid closed loop insulin delivery to see if awareness improves over time. The team aims to develop and validate better tools to measure changes in awareness in real-world glucose-monitoring contexts.
Why it matters
Potential benefit: If successful, this work could lead to better ways to detect and restore hypoglycemia awareness, reducing severe hypoglycemia risk.
How similar studies have gone: Previous screening tools may miss changes in awareness in the era of continuous glucose monitoring, making new tools important and potentially impactful.
